Hello. New here. New to hardware coding. I am using the CubeCell AB02S. This weekend I was able to connect and have the device functioning. Today, I went in and changed the appTxDutyCycle from the default to 180 * 1000 ms. Now, the device will not connect. Just says “Joining” the whole time. Serial output is “join failed, join again at 30s later” I removed the OTAA keys to keep them safe. Also, the White LED flashes 3-4 times when joining. This was not happening before.
Everything was working as expected. I just wanted to not send data so much - eventually every hour, but wanted to try 18 seconds.
/* The example is for CubeCell_GPS,
* GPS works only before lorawan uplink, the board current is about 45uA when in lowpower mode.
