it was my first ABP test for this 32U4/RFM95 china adafruit feather clone, just to see if I didn’t make ‘key’ mistakes
code example is here and here
not much free memory left so what we need is an 'stripped lmic version to gain some memory.
the goal is to send temp and humidity data and we need deepsleep.
regarding the battery voltage (drop) , I didn’t even check that code part/pin … was supprised it measured anything
one thing I noticed immediate, on first boot with a piece of wire antenna on my desk … the packet was seen by 3 gateways, even the one 13 km away … I expected to see only my GW in the console.
that makes me wonder… is the output of the RFM95 that much better than the RN2483 TTN uno clone I build ?
have to check and learn a lot more.
