trinket… isn’t that a fancy Attiny 85 ? I wonder if you have any memory free ?
in void setup()
loraSerial.begin(19200); // lower the speed
…
// Reset is required for autobaud RN2483 into 19200 bps from the
// default 57600 bps
ttn.reset();
ttn.showStatus();
you can have a peek at this code I used with 328p + rn2483
only difference is that that when the rn wakes up it wakes up the 328p… so sleeptimes are dicided by the rn
