  You will have to sync RTC with some NTP server first. See: https://docs.pycom.io/firmwareapi/pycom/machine/rtc/ and https://docs.pycom.io/tutorials/networkprotocols/ntp/ Of course, this means you will need to connect to the internet in some way.

  @DualMatic since the chip using 16-bit words you should provide a 2-byte buffer for the data being read.

  @Eric-Tremblay Ah sorry I had missed that. No, the message is correct. The address is on 16 bits, so takes two bytes to send. What happens when you try a read?

  Hope you managed to solve your problem, OP. You can use TLS encryption to secure the connection on your MQTT broker. I recommend getting more info from here on how to secure your data. This guide was written by the team behind the MQTT broker Mosquitto and is, therefore, reliable and up to date. You can follow their step-by-step guide to configure a professional, secure and performant MQTT broker. I also have several devices in a network and use this encryption system to make sure no one hacks them. Securing data transfer between clients of a network is mandatory.

  @misterlisty If the object is a named tuple, use obj.mac, if it is a simple tuple, use indices and split.

  @kjm said in Exceptions in micro python: ZeroDivisionError: division by zero The super class of ZeroDivisionError is ArithmeticError. This exception raised when the second argument of a division or modulo operation is zero. In Mathematics, when a number is divided by a zero, the result is an infinite number. It is impossible to write an Infinite number physically. Python interpreter throws “ZeroDivisionError: division by zero” error if the result is infinite number. While implementing any program logic and there is division operation make sure always handle ArithmeticError or ZeroDivisionError so that program will not terminate. try: z = x / y except ZeroDivisionError: z = 0 Or check before you do the division: if y == 0: z = 0 else: z = x / y The latter can be reduced to: z = 0 if y == 0 else (x / y)

  Thanks, I was somehow under the impression that Gpy has a 2G fallback.

  @jcaron It's perfect I found what I want thanks a lot ! So if people want to know, in RegionEU868.c the function RegionEU868NextChannel, call the function CountNbOfEnabledChannels which check all the channel that are enabled ( channel enabled, joined and available for transmission) which get you a list of available channel and then it select one randomly from this list. In LoRaMac.c in the function ScheduleTx, there is a while loop calling RegionEU868NextChannel till one channel is available

  @jcaron Thanks for testing this. It seems indeed the most likely conclusion, certainly if the handshaking itself is already over 5000 bytes.

  So I was right, when i connected over UART to RS485 converter everything is working fine. This shloud be mentioned in docs, that you need to use RS485 converter and not to try connecting directly.
