    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 ? 

    Yes that's correct...

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

     No, because in the beginning it was working fine, I have tried many examples on that module... And the other day I saw this error, and unable to program the module .. 

    The last code flashed in module was mesh example code... 

    By the way I thought the same as you, and checked the Hardware first, like voltage on the module supply pin and programmer pin, checked the voltage level as per suggested in datasheet like on reset pin , etc... 

    According to you what else do I test when this kind of issue get generated ?..
