I am powering the device with a battery, however the device does not seem to wake up. I have added the PWM1.h and PWM2.h libraries as well as the void pwmEnable() as per below which is my full sketch. (all keys zero'd out - connecting is not my issue)
The device seems to be working fine when powered by USB. I have been reading and searching for solutions for 2 days now and despite there being many comments about this, I am unable to find a definitive answer or good example (or updated example sketch) to get this resolved, and as such am raising an issue here in desperation to try and get this issue resolved.

300000ms is every 5 minutes. This should not be the issue here. Many LoRaWAN devices only communicate once a day. I have another setup where I use the same boards and transmit only every 30 minutes (1,800,000 Milliseconds) and this seems to work no problem. The issue is when I take it down from 5 minutes and lower... sampling every 1 minute for example is very very unreliable.
I am using this sketch - https://github.com/HelTecAutomation/CubeCell-Arduino/blob/master/libraries/LoRa/examples/LoRaWAN/LoRaWAN_Sensors/LoRaWan_OnBoardGPS_Air530Z/LoRaWan_OnBoardGPS_Air530Z.ino for my HTCC-AB02S.
I am powering the device with a battery, however the device does not seem to wake up. I have added the PWM1.h and PWM2.h libraries as well as the void pwmEnable() as per below which is my full sketch. (all keys zero'd out - connecting is not my issue)

I have been reading and searching for solutions for 2 days now and despite there being many comments about this, I am unable to find a definitive answer or good example (or updated example sketch) to get this resolved, and as such am raising an issue here in desperation to try and get this issue resolved.
