1.7.5 is supporting only COM.X LoraWan 470 and 915 modules but not the 868 MHz version M031-C?

@chefrocker Upvoting your request since I am waiting for the same. Unfortunately the 868 module seems to need a firmware update to match the same set of AT commands as the others. See https://community.m5stack.com/topic/3199/uiflow-1-7-5/11 for details.

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.

I can confirm they are for M2 screws. E.g. for mounting a stick on the battery stick you'll need M2x10mm like shown here https://m5stack-store.myshopify.com/collections/m5-hat/products/m5stickc-18650 Turns the Stick into a nice handheld device for mounting a joystick, thermometer etc.
