  • Please correct me if I'm wrong. 

    You have 2 setups, both with the BT840E module. And on one of the custom board, the module worked fine and you don't have any problem to program it. But on the other custom board, you can't program it ? 

    If it's the case, I would suggest to double check the PCB and soldering, connection.  It's more likely a hardware issue.
