using frequence 868Mhz about rflink32

[cpainchaud]

Hi,

It's all about your receiver, what radio hardware are you using? Also if you don't mind what are the shutters brand and model?

thank you

[geromey]

This is Heltec WiFi-LoRa 32 V2. The shutters are Provalux.

Thank you !

[cpainchaud]

this board has a built in receiver which is tuned for a specific radio band, did you purchase the 868Mhz one?

[geromey]

Yes

[cpainchaud]

ok then did you select hardware SX1278 in Radio settings? If so then I just realized the UI is not showing the frequency parameter :D
in serial type this command: 10;config;set;{"radio":{"rx_freq":868950000}}
That will set frequency to 868.95 Mhz

That said can you tell me which hardware you used for your 433mhz receiver? Because Lora Heltec cannot transmit with their current pinout as far as I can remember

[cpainchaud]

Oops I meant hardware = SX1276 for the 868Mhz brand

[satinebm]

Argh, the hardware failed to initializ

Now trying to initialize hardware 'SX1276
Initialized SX1276(freq=868.95Mhz,br=9.600kbps,rxbw=250.0khz)=-2

are you using the official firmware from downloads page or compiled it yourself? Also @satinebm is not @geromey so are we talking about the same hardware issue here?

[satinebm]

Yes we are talkin about the same hardware issue. Sorry for the confusion.
We are using the official firmware.

[cpainchaud]

ok official precompiled firmware is created for generic ESP32 dev board.

Each board maker is making its own pinout for the various usages. In your case you have 2 solutions:

• re-compile yourself with the right board ID in platformIO (heltec_wifi_lora_32_V2) and in Radio settings/menus change RX CS, RX Reset, RX data (SX1272's DIO3)
• in Radio settings/menu : 'guess' what the right pins are for RX CS, RX RESET, RX DATA from Heltec docs

I have on such board around and will try to help you tomorrow, may be right a KB about it

[geromey]

Hello Christophe,

We start to unerstand how settings works. We are not sure which pin is the RX DATA.

Here is the pinout of our board. Could you tell which one it is ?

We’re you able to get this working? I’m trying to do the same. I believe rx data is pin26

[cpainchaud]

@caliKev first of all you must ensure that you have compiled the firmware for your board. the pre-compiled ones are for ESP32-Dev-board. 'heltec_wifi_lora_32_V2' is the one you should pick
