  Hello bruno, this is what I did, instead of using the exemple code, I can set and catch the timeout error hence loop while not joint. while lora.has_joined() is not True: try: lora.join(activation=LoRa.OTAA, auth=(dev_eui, app_eui, app_key), timeout=20000, dr=0) except Exception as e: print('Not joined yet...')

  @brotherdust Don't supply 3.3V to the 3.3V pin. This is an output only. It can burn up the power supply chip.

  Hi @gruia-nichita I'm using LoPy with Blynk via WiFi, but am also interested in using it with LoRa, let me know if you find a solution (I haven't looked at LoRa+Blynk with enough detail yet...) I'm using BlynkLib : https://github.com/vshymanskyy/blynk-library-python

  I can confirm @River is correct, the LDO automatically switches modes, there is no GPIO pin involved in this

  @wstallwood said in OSError: [Errno 11] EAGAIN: https://forum.pycom.io/topic/502/socket-send-msg-timeout Hi, in order to catch an error without crashing you can just wrap the call with: try: s.send(data) except OSError as e: if e.args[0] == 11: # EAGAIN error occurred, add your retry logic here A list of what all the error numbers mean can be found in this file: https://github.com/pycom/pycom-micropython-sigfox/blob/5bed5e9a84bb1abfc4d59476f3f62b38920c5eda/py/mperrno.h Onto why this error occurs, having a look at the lora source code you can find that this error is raised here: https://github.com/pycom/pycom-micropython-sigfox/blob/master/esp32/mods/modlora.c#L2082 This error is raised if send_lorawan returns zero, which can happen for two reasons, the message was added to the queue (which is what I believe you are refering to with the duty cycle limiting) or there was a LORA_STATUS_ERROR.

  @jeromemaquoi really better if you show some sample what do. As you can read here detail was provided by chat but better is write on the forum and ask question with sample and exact error message.

  Hi, We do not currently support connecting to bluetooth devices with a passcode. This feature is on our firmware roadmap and will be released in the future but I cannot provide a specific time frame.
