Tutorial: Using COM.LoRaWAN in UIFlow
I wrote a tutorial on using COM.LoRaWAN in UIFlow.
This is my first tutorial at hackster.io, I would highly appreciate some feedback.
Great job! looks amazing, thank you for supporting and sharing it with the community!

Great job. Does this work the same with the old (blue) LoRaWAN module?
@lasniko you could reuse some parts of the tutorial, but the older blue module uses completely different AT-commands.

thank you very much for this very valuable information for a beginner like me.

please go on with it, would like to find an way to upload sensordata to TTN via ABP.
I have only an singleGateWay here and it does not let my join via OTAA.
I am stuck here.
many greetins from danube/austria

Hello @sodoku. Many thanks for sharing the tutorial! I found it on m5stack.hackster.io and it helped me a lot. Registered two COM.LoRaWAN 868MHz modules sucessfully with TTN and managed to see uplinks (alas with long join latency and lots of retrying uplinks though I am in the very middle of Berlin - it seems coverage still has to improve a lot). I am still struggling with the adaption of the official P2P example. Especially regarding use with a sensor in a setup without use of buttons to initiate data requests. If you'd find the time to extend your tutorial his would be much appreciated.
Also I wonder about the real life range of the modules. I have currently set them to 5V and cannot pull data beyond 20m distance, line of sight. Seems odd ... what are your experiences? Can this be enhanced using 12V? Maybe a faulty antenna connection?
As a side note - all blocks in Flow 1.7.2 are dedicated to the older blue modules - but an implementation for the M031-C is in development, as confirmed by M5Stack support.
@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.
@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:
