Failing to Pair with "Bluetooth Low Energy" Desktop (V3.0.0)

Hello Amanda,

I'm so sorry. It turned out, that I've (again) stumbled over the Mac / Segger MSD problem (https://wiki.segger.com/J-Link_OB#Problem_description). After disabling MSD on the eval board connected to the nRF Connect for Desktop, everything works as expected.

Thank you very much for your Time.

Best regards,

Torsten

Hi,

Are you using DK or custom board? Do you have DK to test with devzone.nordicsemi.com/.../17.1_5F00_ble_5F00_app_5F00_hrs_5F00_pca10040_5F00_s132.hex for nRF52832DK; devzone.nordicsemi.com/.../17.1_5F00_ble_5F00_app_5F00_hrs_5F00_pca10056_5F00_s140.hex for nRF52840DK?

I cannot reproduce with those image on DKs pairing with the nRF Connect for Desktop/BLE app. Is it possible to test on your side?

Is it possible to capture sniffer log before the application connect to the nRF Connect for Desktop/BLE app? I need the sniffer log starting before the device connects to app. Thanks.

Hi Amanda,

please see the already attached `2022-01-07T07_02_32.114Z-log.txt`I guess that's what you name a device log. The sniffer log is in the already attached `ble_pair.pcapng` (can be opened, using Wireshark).

I'm using a third party BLE library for nRF52. But, as I wrote, I suspect the issue to be in the nRF Connect Desktop application, not in the firmware. (Because of the missing Public Key Exchange [which has to be initiated by the Controller, not the Peripheral] and because the provided binary [gpio.hex] works against other generic GATT clients)

If you provide me a binary, I would be happy to test your binary against nRF Connect Desktop.

best regards,

Torsten

Hi,

Do you see any error on device log? Please provide the device log and sniffer log which captures before connection.

Are you developing with nRF5 SDK or NCS? Which version?

What is the DK to run the image?

Could you test with Heart Rate Application? Do you see the same issue?

Regards,
Amanda
