Outputting Bresser data on TTGO ESP32 OLED board about bresserweathersensorttn

[mczakk]

I seem to have got it working properly!!, check it out and see what you think?

[mczakk]

All seems to be working ok now, though for some reason it refuses to compile using Arduino ide 2.0 on my Ubuntu 22.04 laptop (works fine using IDE 1.8 on another Ubuntu 22.04 one though!)
one thing that would be useful from a data representation point of view - the part in BresserWeatherSensorTTN.ino (lines1395-1423) where it checks the weather data and fills it with suspicious dummy values - is it possible to NOT report to TTN if those values are present? It makes a mess of my graphs!!
Thanks again for all your help with this :)

[mczakk]

I've now added updated code, which will produce a string called 'global_tbuf'
which i can print out, (line 1534)
Do you know how i can print this on the oled?

[matthias-bs]

I'll have a look at it later.

[matthias-bs]

If you create a fork of my repository, you can get updates from it later on, even if you made your own modifications. And the CI workflow (continuous integration) will compile your code whenever you check in any changes and help to check it. (see the item "Actions" at the top)

[mczakk]

Forgive my ignorance about all things github, but would a fork be like an amended version of your code? And does it matter that I've just mashed up your code with uspizig's? I will happily give you both the credit you deserve!

[matthias-bs]

No worries!
That's the power of open source and community driven development! The selected MIT license allows and encourages to do this! Did you see how many libraries I'm using in my project and that it is mainly based on the LMIC libraries, RadioLib and rtl_433? So the project is in big parts the result of other people's work with a few changes and additions by myself...

And GitHub makes this sharing, reusing, remixing etc. quite easy and comfortable.

If the modifications of your fork are of general interest, you can create a pull request and I could re-integrate them in my project.

[matthias-bs]

BTW: Did you see that @Uspizig used some parts of my code in https://github.com/Uspizig/Bresser_Weather_NEW/tree/main/WeatherDecoder_LORA_RFM95Only? ;-)

[matthias-bs]

I have made a fork and did some modifications (see history for explanation):
https://github.com/matthias-bs/TTGO-ESP32-Bresser-with-display
Your code was valid, but the handling of the time string was unnecessarily complicated. I know, string handling in C is more difficult than it should be...

I hope I did not make any mistakes. Please let me know if it works.

Please check how to handle the display update in case of no sensor data was received in the current cycle (ws < 0).
You could either skip displaying this part or show that no data is available. Using ws < 0 as an index into the data structure would cause a runtime error (crash).

[matthias-bs]

You have put delays of 10 and 15 seconds in the display function to allow reading before the contents are changed. This might cause problems in the LoRaWAN protocol handling. After sending an uplink message, other things might have to be done in time, e.g. receiving an acknowledgement, parameter changes, the network time etc.

I will try to address this later.

[mczakk]

Thankyou for sorting out the time string, it took me a while to work that one out, yes string handling does seem overly complex when compared to python!
Your code compiles perfectly, I've made a couple of changes in the display which i will try and change on the fork, hopefully I'll get it right!

Regarding the delays, and potential problems with the timing, is that not just a function of when the display function is run? Would it not be easier to wait until the LoRaWAN bits were done before running the display update, after all, we have five minutes after the data is sent to ttn.
Is it as simple as just moving the call to 'displayWeatherData()' ?

[matthias-bs]

Yes, in this case it would be the easiest solution to call displayWeatherData() just before entering deep-sleep mode.

The more complicated solution would be to keep the state (current page) inside the function and compare the current time to the last time the function was called and call it again when due. This would be the desired solution if the sketch were to run continuously (instead of going into deep-sleep mode after each cycle).

[mczakk]

where would be the best place to put it in your opinion?
Also your comment about the [ws] value was interesting, I've not really had any problems with that other than the occasional zero value being reported.
Apart from when i tried to connect the esp32 to my raspberry pi, it seemed to throw up errors in the serial monitor that i wasn't seeing when it was connected to my windows laptop!
Actually, I am seeing the same errors through my linux machine:

It certainly wasn't doing this before!!

[matthias-bs]

Regarding the displayWeatherData() function call:
https://github.com/matthias-bs/TTGO-ESP32-Bresser-with-display/commit/0390b11efcc1b76db3a77867a5404ac1a82e4b34
I have moved it to a location just before going to sleep after a successful transmission if nothing else is left to do. I hope I got the passing of the index into the data structure right without compiling/testing...

[matthias-bs]

The parity errors above mean that radio signal is disturbed, either directly (by radio emissions of your raspberry/laptop) or by the power supply of your TTGO board.

If you want to save battery power in the field, you should switch off these debug messages before deploying the sketch onto the target device.

Thanksfor creating the pull request, though i did accept your changes before compiling and uploading!!

[matthias-bs]

Nice matrix pattern! ;-)

You could install the exception decoder to locate the error: https://github.com/me-no-dev/EspExceptionDecoder

It's a little bit difficult for me to help you, because I do not have this board. I could modify the display function in order to check if the data is passed to it correctly. But currently I cannot make any promises when I will find the time.

At least GitHub's versioning will allow you to revert the last changes.

Sorry for this!

[mczakk]

d'oh, it seems i didn't install the right board manager when i moved to using the arduino ide on my linux machine from my windows one, will try your revisions again and report back

[matthias-bs]

I just made the same mistake and didn't notice the compiler warnings about redefinition of the OLED interface pins...

[mczakk]

has WeatherSensorCfg.h been changed at all, as i wasn't getting any of these pragma messages before?
I have tried board revision V2 and V2.1 1.6.1 (the latter is what is printed on my board)
with either i now get nothing on the screen , and no ttn connection

also, i'm confused by this in WeatherSensorCfg.h:

#elif defined(ARDUINO_TTGO_LoRa32_V2)
    #pragma message("ARDUINO_TTGO_LoRa32_V2 defined; using on-board transceiver")
    #pragma message("LoRa DIO1 must be wired to GPIO33 manually!")
    #define USE_SX1276

on my board (and according to @Uspizig) the lora DI01 is connected to gpio12?

[mczakk]

trying again with the latest version of BresserWeatherSensorReciever, board set to TTGO esp32 V2.1.1.6.1
ok, got the serial messages back, it's recieving, but bad data, and doesn't seem to be trying to connect at all to ttn

also , in WeatherSensorcfg.h (lines 46- 85)
should all these definitions be commented out? the way i read it is thath the board definition/revision is set in the ide?

[matthias-bs]

Yes, the board definitions should be left commented out if configuration via the IDE is supported for your board (please see the Readme.md).

And no, you do not get bad data - what you see are the flags which data is available in the current message (well, this is not clear from the output).

Do you get a TTN connection with any of the two board versions? Which pin numbers did work four you previously? Maybe I made a mistake with the pinning.

[matthias-bs]

For V2, a connection between the ESP and the LoRa radio (which is only used by LMIC) is missing entirely. You have to connect a wire to any unused GPIO pin (I selected pin 33 for consistency with v21new).

For v21new, all radio pins are connected to the ESP32 and there are the appropriate defines in pins_arduino.h

// SPI LoRa Radio
#define LORA_SCK    5   // GPIO5 - SX1276 SCK
#define LORA_MISO   19  // GPIO19 - SX1276 MISO
#define LORA_MOSI   27  // GPIO27 - SX1276 MOSI
#define LORA_CS     18  // GPIO18 - SX1276 CS
#define LORA_RST    23  // GPIO23 - SX1276 RST
#define LORA_IRQ    26  // GPIO26 - SX1276 IRQ (interrupt request)
#define LORA_D1     33  // GPIO33 - SX1276 IO1 (for LMIC Arduino library)
#define LORA_D2     32 // GPIO32 - SX1276 IO2
```

[matthias-bs]

According to https://github.com/matthias-bs/TTGO-ESP32-Bresser-with-display/blob/main/BresserWeatherSensorTTN2.ino (I did not change your pin numbers) you used the following:

#if defined(ARDUINO_TTGO_LoRa32_V1)
// https://github.com/espressif/arduino-esp32/blob/master/variants/ttgo-lora32-v1/pins_arduino.h
// http://www.lilygo.cn/prod_view.aspx?TypeId=50003&Id=1130&FId=t3:50003:3
// https://github.com/Xinyuan-LilyGo/TTGO-LoRa-Series
// https://github.com/LilyGO/TTGO-LORA32/blob/master/schematic1in6.pdf
#define PIN_LMIC_NSS LORA_CS
#define PIN_LMIC_RST LORA_RST
#define PIN_LMIC_DIO0 LORA_IRQ
#define PIN_LMIC_DIO1 33
#define PIN_LMIC_DIO2 cMyLoRaWAN::lmic_pinmap::LMIC_UNUSED_PIN
#else

(Provided ARDUINO_TTGO_LoRa32_V1 was really set.)

Maybe I made some mistake or maybe you have an inconsistent mix of old and new code...

In pins_arduino.h, OLED_SCL, OLED_SDA and OLED_RST are already defined (so please do not re-define it in your sketch). According to this, your board should be V2 or V21new.

Again from variants/ttgo-lora32-v21new/pins_arduino.h:

// I2C OLED Display works with SSD1306 driver
#define OLED_SDA    21
#define OLED_SCL    22
#define OLED_RST    16

[matthias-bs]

Again from our discussion three weeks ago: #38 (comment)
According to this, you have a V2 board (which needs the extra wire) and you decided to connect it to pin 12, so you have to change this accordingly:

#define PIN_LMIC_DIO1 33

I'll call it a day now, otherwise I'll get a headache...

[mczakk]

I'll call it a day now, otherwise I'll get a headache...
Ill have a look at your comments in the morning.
Really do appreciate your time in trying to get this sorted for me. 😁👍

[mczakk]

I think I might have found the issue:
I told you that I'd moved to my linux laptop to use the arduino ide-
when i looked at the board managers, it seems that the linux ide has a later version of 'esp32 by espressif systems' installed (v2.0.6)
the screenshots below show the difference in the board managers:
linux IDE

windows ide:

as you can see, the boards available in the windows (v 1.0.6) version of esp32 are different, and there is no option to select 'board revision'
I tried uninstalling the v1.0.6 version in the windows ide, and when i entered the same url in the 'additional board managers' section in preferences, i still got v 1.0.6, with no option to install v2.0.6.
installing the sketch works perfectly using the windows ide.

[matthias-bs]

I think the board selection can be changed by editing the "Board Manager URLs" in the Preferences:

I remember I had a similar problem a while ago.

I have the IDE V2.0.3 installed on Linux and all three variants are available.

[mczakk]

Yes, that is what is confusing me, I entered the same url (https://dl.espressif.com/dl/package_esp32_index.json) into the board manager preferences on both my windows and linux machines. the windows machine gives me v1.0.6 (and the sketch compiles and uploads perfectly with the old code) and the linux machine gives me v2.0.6 and doesnt compile properly (giving the errors discussed above)
I will try using the same url as in your screenshot and see what happens

[mczakk]

ok, changed board manager preferences to that above, installed additional libraries - theengsdecoder and nimble.
downloaded latest versions of BresserWeatherSensorTTN, WeatherSensorReciever and TTGO-ESP32-bresser-with-display to windows machine, board set to TTGO Lora32-OLED revision V2
waiting on compilation..... and it fails to work correctly, compiles and uploads ok, although i do get this message:

[matthias-bs]

The messages are just for information which pins and which transceiver will be used (based on the board settings).

The question is: which pin actually worked for you or to which ESP32 GPIO pin did you connect the DIO1 wire?

If I got it right from the conversation, you used GPIO12 (not GPIO33). If this is true, you have to change the define for PIN_LMIC_DIO1 accordingly.

Could you please change your debug level?

[matthias-bs]

BTW: You are switching between two computers and updating the Arduino development environments... Did you remember to apply the configurations and fixes for the LMIC libraries?

[mczakk]

Ah, I got confused because some of the images of pin maps I've seen have pins labelled as different numbers!
I will change PIN_LMIC_DI01 TO 12, just in ..TTN2.ino yes?
Will see if it compiles properly now!

[mczakk]

nope, still didn't work, was wondering if i needed to change this bit? (lines 187 to 205 in BresserWeatherSensorTTN2.ino

on compiling

[mczakk]

The pin config bit does say RST - >12 and GDO2/G1/GPIO->12, so I guess that's where the problem lies!

[matthias-bs]

Well, the question is not if it compiles properly, but if the pins matching your board (and your extra wiring) are selected!
The compiler can't know this! The pragma messages are just for information how the defines are finally translated to the GPIO numbers.

To go one step back, please check which boards (are all your boards of the same version?) you have (e.g. by comparing it with https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-2/11973) and check which pinout your board has. If your board is this weird V2 version, check if you have the extra wire for DIO1 and to which GPIO it is connected. Then make sure this GPIO is selected in the defines you are going to uses. Then compile and compare the pragma messages with the GPIO numbers you intended to be used.

If all this fails, please go back to the versions (according to the date) and IDE settings which worked for you previously (and then check what has been changed since then).

What the...

in
https://github.com/espressif/arduino-esp32/blob/master/variants/ttgo-lora32-v2/pins_arduino.h:

#define LORA_RST    12  // GPIO14 - SX1276 RST

So the actual define and the comment are different!!!

And even worse, according to https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-2/11973, the radio's reset pin is actually connected to the HW reset and therefore cannot be controlled by SW. Therefore they propose to assign cMyLoRaWAN::lmic_pinmap::LMIC_UNUSED_PIN to it! What a ****!

Did I mention that Lilygo does not provide schematics for all versions?

Probably the circuit is designed in a way, that you could wire an additional GPIO pin to the radio's reset input and then assign this to LMIC. On the other hand, the reset is probably also controlled by SW (via SPI).

To go one step back, please check which boards (are all your boards of the same version?) you have (e.g. by comparing it with https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-2/11973) and check which pinout your board has.

Then compile and compare the pragma messages with the GPIO numbers you intended to be used.

i checked that thread and the board i have isn't shown on there - these are the boards i have (i have two, and they are slightly different, one is marked T3V1.6, (this one is working ok out in the field), the one i am currently trying to get to work is marked T3_v1.6.1)):

If all this fails, please go back to the versions (according to the date) and IDE settings which worked for you previously (and then check what has been changed since then).

The main thing that has changed is that since the update of the esp32 board manager from 1.0.6 to 2.0.6 all the errors have occurred.
as i stated in my post above, version 1.0.6 only has one option for TTGO LoRa32 OLED V1, whereas v2.0.6 has TTGO LoRa32 OLED with three different options in the 'board revisions bit of the 'Tools' dropdown (which isn't present in V1.0.6)

OK, not sure i understand this, but just tried compiling with board revision set to TTGO LoRa v1 (NoTFcard) and it seems to work ok, reporting and displaying ok, but the message sent to ttn is different, so the old payload formatter is faioling with a mask length error!

[matthias-bs]

Which errors have occurred?

T3_V1.6.1 should be compatible to v21new (http://www.lilygo.cn/prod_view.aspx?TypeId=50060&Id=1271&FId=t3:50060:3)

The payload length should only depend on the selected options in BresserWeatherSensorTTNCfg.h.

Maybe the change comes from the way I'm dealing with PIN_ADC3_IN. I'm only defining this for my own LORAWAN_NODE board, because I currently do not have sufficient information on how to use this in a useful way for other boards.

So, for your purpose, if you have updated BresserWeatherSensorTTNCfg.h from GitHub, just enable it for your board as with the previous version and the payload length should be the same as before (even if the reported voltage is not useful).

[matthias-bs]

V2
https://github.com/lnlp/pinout-diagrams/blob/main/LoRa%20development%20boards/TTGO%20LoRa32%20V2.0%20Pinout%20(LLP%20v3.0).pdf

V2.1.6
https://github.com/lnlp/pinout-diagrams/blob/main/LoRa%20development%20boards/TTGO%20LoRa32%20V2.1.6%20Pinout%20(LLP).pdf

[mczakk]

looks like the board I have in the feild is a v1.6, and the one on my desk is a v1.6.1
Think i've solved the payload length issue, set #define SENSOR_ID to on, will see what happens, at the moment its taking 10+ minutes to compile for some rreason.....

[matthias-bs]

Ah, ok. If you are using decoder_basic.js, you are expecting the ID (I did not remember that), but you are also expecting supply_v and battery_v (i.e. PIN_ADC3_IN has to be defined).

[mczakk]

sorted it out now, PIN_ADC3_IN was not defined.
works fine (but compiles very slowly) on windows now,
still having a problem compiling it from linux - something to do with esp32 Preferences.cpp

[matthias-bs]

Would you like to investigate why it fails with IDE 2.0?

For the second issue: please check the define WEATHERSENSOR_DATA_REQUIRED. If this define is set and weather data is incomplete/not available, the sketch enters sleep mode without sending data.

Another solution would be to process the data only if the valid-flag was set.

[mczakk]

Would you like to investigate why it fails with IDE 2.0?
I'll try, the ESP decoder you mentioned doesnt work with ide 2.0, so i cant decoded the stack trace or backtrace, I'll post them on here, but i need to have the board running to collect data,
For the second issue: please check the define WEATHERSENSOR_DATA_REQUIRED. If this define is set and weather data is incomplete/not available, the sketch enters sleep mode without sending data.
trying with this.....
Another solution would be to process the data only if the valid-flag was set.
