I recommend downloading M5Burner from https://m5stack.com/pages/download and burning the latest UIFlow version first.

@holgerw-0 didn't see your question. Did you manage to get it working?

I haven't used ABP so far, but you should be able to use it by setting the ABP settings from TTN:

AT+NwkSKey=kkkk
AT+AppSKey=kkkk
AT+DevAddr=kkkk

and then switching from OTAA to ABP:

AT+OTAA=0

@anvalin I am glad I could help. I haven't done an example with sensors yet, because M5Stack said they would release support to the module in UIFlow which would make my example obsolete. I might still do it if I find the time.

I think the input power doesn't matter since the 12V will be regulated down to 5V anyway. I am also in Berlin. With a simple P2P test and a TTGO board in my window I recieved packages about 400m away. My record though was getting a connection to an outdoor TTN gateway which is over 8km away!
LoRa works best with a line of sight, any buildings inbetween can significantly decrease the signal.

@TheAlphaGhost which device are you using? At least one of those pins 23 and 19 that you are using is connected to an internal for most of the devices.

Maybe Thonny works for you?

@ZigedZaged123 try installing the FTDI drivers: https://www.ftdichip.com/Drivers/VCP.htm

@lasniko you could reuse some parts of the tutorial, but the older blue module uses completely different AT-commands.

@hashman73 which device do you have exactly?

I wrote a tutorial on using COM.LoRaWAN in UIFlow.
This is my first tutorial at hackster.io, I would highly appreciate some feedback.

It ignores the data when using "GET", if you set it to e.g. "POST" the python code includes the data.
