NRF52840 Dongle not working properly

user93890

Hi,

I have a problem with my nrf dongle i have working example on the DK and i could not put this onto the dongle. I tried dedicated examples and they are not working too. For example ble app blinky the softdevice and the app file were good, device had green light however when i tried to connect via my phone (nrf connect app) it could not connect and the dongle changed its light to red and was not able to detect by nrf connect on PC. Also i could not programm the bootloader (open_bootloader) from examples for PCA 10059. I do not know what to do next.

    With pleasure it took me 9 hours yesterday and still the same problem. There is no ble_lbs_init() in sdk confis LBS is disabled and still it appears.

    I see no reason why the LBS service should be part of this project from the main.c file. What SDK example did you base your project on? The ble_app_uart nor the usbd_ble_uart example projects have the lbs service enabled by default.

    To make sure that you are connecting to the correct board, can you try changing the Device name on your Dongle, and connect to the new name to check that the lbs service is still present.

    Best regards,

    Simon

    Hi

    I asked one of my colleagues that works with the iOS version of the nRFConnect app, and apparently, the iPhone/iOS caches services, etc. until you do service discovery again. You can try erasing bonding information entirely on the phone side to make sure it's not cached anymore, and then try reinstalling the app and make sure service discovery is being done upon the new connection.

    Best regards,

    Simon
