OTAA activation not working on TTN

[mo-norant]

Hi,

when i am activating over OTAA the Activation frame gets recognized, but the payload frames are not transmitted because it's not connected on the TTN network. APB activation does work without any problems.

Theory, does the low RSSI of -119 mean something?

Here you can find my code.

OTAA is confirmed not working: #21 (comment) only ABP !

[mo-norant]

Yeah indeed, does somebody has an answer to the code?

Hum not sure to understand what is your problem as you stated it works fine in ABP mode no ? Which version of board do you have ? mine is 1.1 and not working with that code (no TTN connection and OLED display doesn't work too :(

OTAA was working with the supported versions of the boards (up to V0.7) last time I checked.

Let's concentrate on the support of the newer (V1.0 / V1.1) board versions before talking about OTAA, see #21 #19
