nRF52840 Dongle stopped working

[Seema]

Hello,

I was using the usbd_ble_uart code for the nrf52840 dongle. When I connected the dongle to u-link 2 debugger and used keil uVision I was just doing my settings in the target options and the dongle has stopped working.

I have tried to reset the module and every other means but the device is not recognized by my computer nor is the LED Blinking.

I have no clue what has happened with device. This has happened once before and I had bought a new dongle and the same problem has occurred.

Could you please help with this problem.

Will be waiting for your response.

Thank you

Seema

Have you by accident removed the bootloader from the dongle?  Do you have a different programmer that you could test to program the dongle ?
