Data size no match with Raspberry Pi pico

Hello,

I have connected the E220-900T22D module to the Raspberry Pi pico as follows:
Pico ----- E220
1 -------- 4 (TxD)
2 -------- 3 (RxD)
15 ------- 5 (AUX)
21 ------- 1 (M0)
19 ------- 2 (M1)

I use the UART0 on the Pico (pin 1 and 2). I have also connected a 4.7kOhm pull-up resistor to each of TxD, RxD and AUX.

Unfortunately, I always get the following message:

Initialisation: {} Success
Retrieve configuration: {} Data size not match!

Traceback (most recent call last):
File "", line 29, in
File "/lib/LoraWanE220/lora_e220.py", line 245, in print_configuration
AttributeError: 'NoneType' object has no attribute '_COMMAND'

What could be the reason?

best regards
Woto

How do 3 ebytes work together?

Hello, I need to use 3 ebytes for a project and 1 ebyte must communicate with all of them. Also, the data needs to go every 1 second. We communicated 2 ebytes with a loop, but it worked very slowly and we could not add the 3rd ebyte. Thanks in advance.

uart: tout_thresh = 244 > maximum value = 101

Hey everyone,

I am trying to set up a communication between two esp32 (WROOM-32) with a EBYTE E220-900T22D.
The ESP is flashed with Micropython 1.21.0 (I also tried 1.22.0) and I did the wiring as described by xreef.

Until now I wasn't able to set up any communication.
Currently I get the following error (sender and receiver):

uart: tout_thresh = 244 > maximum value = 101
Initialization: {} Success
Set configuration: {} Data size not match!
Send message: {} Success

Even though it tells me 'Success', no message is received at the other ESP.
I'm using the two examples

• send_fixed_string_message.py
• receive_string_message.py

I'm really hoping someone can help me here.
Thanks
M

Save mode returned not recognized!

Hi!, I'm testing the library with a RP2040 and a E220900T22D, seems like something went wrong using get_configuration()

from lora_e220 import logger
from lora_e220_operation_constant import ResponseStatusCode
from machine import UART

# Init Lora
# https://github.com/xreef/EByte_LoRa_E220_micropython_library
uart1 = UART(1)
lora = LoRaE220('900T22D', uart1, aux_pin=7, m0_pin=2, m1_pin=3)
logger.enable_debug = True

code = lora.begin()
print("Initialization: {}", ResponseStatusCode.get_description(code))

# read config
code, configuration = lora.get_configuration()
print("Retrieve configuration: {}", ResponseStatusCode.get_description(code))
print_configuration(configuration)

Am I doing something wrong?

Data size not match...

Hello everyone, I'm using this library to employ several Lora devices, in this case the e220-400t22d.

However in several raspberry pico's, such as raspberry Pico x8, waveshare rp2040 plus X2 and even using the Raspberry Pi 3b X1 with the developed library.

In the function getconfiguration of your examples get the error:

Data size not match.

I'll appreciate if anyone had any idea to solve this issue.

In advance rhanks
