  daniel - As with many IOT apps they need to run off batteries for years. I am working on a Lora AG application like this so Sleep functions, RTC memory for saving variables, power consumption in various sleep modes is critical. Other functions like Lora Transmit followed by a Sleep call - does transmission complete before sleep? etc. These are some of the issues I have seen with some Lora IOT apps. I will willing test as soon as available.

  Thanks sakis. Apologies - I was looking in the wrong place for the LoRa documentation - I expected it to be in the Pycom specific modules section, because I assumed that general MicroPython documentation would not contain any hardware info at all. Oops.

  Is it ok if the U.FL cable connector touches the case of the reset switch?

  I managed to fix it now. I had to telnet to the ip, it was buggy as hell though, I had to keep pressing ctrl+c for couple of times until it finally worked and I soft factory erased it after. Nevertherless, you should mention how to do a hardware factory reset in the documentation. Now with the Lopy i'm trying as a nano gateway, the same code mentioned in a post on the forum, just printing ACK if it managed to connect to the gateway, it'll stop after few minutes for some unknown reasons.

  Hello, Yes, it has been supported since the first release. Just pass adr=True to the LoRaWAN constructor. Check the init method in the docs: https://docs.pycom.io/pycom_esp32/library/network.LORA.html?highlight=lora Cheers, Daniel

  Yes, it is perfectly possible and our customers in New Zealand are doing it. You just need to use the add_channel and remove_channel API. Please have a look here: https://docs.pycom.io/pycom_esp32/library/network.LORA.html?highlight=lora#network.lora.add_channel Cheers, Daniel
