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.

  • Hi

    Does the BLENano2 module have an external LF clock connected? Most modules don't, and all our examples configure this LF clock to be used by default. If the LF clock is not present on your module, please make the following changes in your sdk_config.h file in order to use the internal RC oscillator instead.

  • Thank you for your reply

    I tried that setting.
    But the problem did not improve.

  • 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,
