I have two HTCC-AB02 boards which I am having issues with.
both have the same code uploaded to them, but give different results.
I have tried uploading from both Arduino IDE and Platform IO - no difference.
Code is below:
#include "LoRaWan_APP.h"
#include <Wire.h>
#include "HDC1080.h"
#define rainPin GPIO1
int rain = 0;
int finalrain = 0;
uint16_t vbat;
uint16_t cnt;
void cntIncrease();
/*
* set LoraWan_RGB to Active,the RGB active in loraWan
* RGB red means sending;
* RGB purple means joined done;
* RGB blue means RxWindow1;
* RGB yellow means RxWindow2;
* RGB green means received done;

AB02 number one will try and join, but will always fail. It will try different frequencies, but always with DR 5. (other boards I have cycle through different DR values until join is successful)
AB02 number 2 will accept a successful upload, but then does nothing. pressing the reset button only gives the serial output : ‘Copyright @2019-2020 Heltec Automation.All rights reserved.’
pressing and holding ‘USR’ while pressing and releasing ‘RST’ gives ‘bootloader Rev 1.0’.
Running the same code on a board that is known to be working gives expected results.
Am I to accept that these two boards are just dead now?
EDITED: Board AB02 number 2 is now working correctly, I have no idea why, the only difference is that i used platform io to upload the sketch and it now works and sends data via TTN as desired!
Board AB02 number one is still stuck on trying to join at DR5 with no success…
