Even if the same program (BLE communication) is written to the same module (nRF52832), only one of them starts BLE communication.

Hello

I am trying to do BLE communication using nRF52832.
I wrote the exact same program on a module (BLENano2) with the same nRF52832 chip, but one was able to do BLE communication but the other wasn't able to do BLE communication.
What is the cause of this difference?
Is there a solution for this phenomenon?

Thank you.

Are the two boards you are programming identical? In that case, it's likely a hardware issue in the faulty board. Can you upload the BLENano2 datasheet so I can take a closer look at it, please?

Best regards,

Simon
