Ble Characteristics error

[Mr.NCK]

Hi,

  I have written the BLE UART code With custom characteristics. I have flashed the code to DK and tested it. but that was not working correctly. Then I  flashed the sample peripheral UART from the SDK. The code has flashed successfully. But, The device is still followed up with the custom characteristics. It hasn't followed the characteristics which are mentioned in the SDK Sample code.

Exactly, I have flashed the peripheral UART Sample. It needs to show "Nordic UART Service". But, It shows "Unknown Service"(Which I developed in the previous code). and one more thing it's happening only on this board. I have checked with one more board that is working fine.

Kindly, Let me know how can I resolve this.

Thanks & Regards

That is strange, Is it possible that this is related to how your phone OS is caching this device data? Just to be sure erase the whole chip before reflashing just to be sure that you have correct image on the DUT.

Can you test this from nRF Connect for Desktop BLuetooth Low Energy tool rather than phone on the other end, just to eliminate any anomalies on the phone OS end?

Yes, my phone has the issues. I don't know what is that issue. Is there anyway to resolve those issue?

To test it in the nrf connect desktop, Do I need any dongle??

Not easy to say what the issue is without understand the underlying communication between you phone and the nRF device. If you have BLE sniffer or nRF Sniffer, you can sniff the connection to see if there has been any errors or other inconsistencies in the data transfer packets and their timings.

A nRF dongle or any other nRF DK is required to work along with the nRF Connect for Desktop app.

Thank you so much, I have cleared that issue by rebooting my phone.
