Suddenly the red light on my new device stop working and bluetooth is not working. Should the red light always light?

Hi,

Could you tell me what is your device? And which sample are you trying on it?

Best Regards,

Hi!

My device is nRF52840 Dongle. I am trying to connect to a ios device(iphone 11 pro).

My case is that I am trying to remote control my device by using Vysor software (via bluetooth). https://www.vysor.io/. 

Using this manual: 

Nordic Dongle

• Plug in the device. Press the Reset button to get into the bootloader. The reset button is sideways, next to the regular white switch. See diagram above.

Flash this hex flash file using nRF Connect Programmer.

Is your device ( Dongle ) being detected by your PC and the Programmer App?

Have you checked the Getting Started Guide for the same?

Yes, the PC and program app register the dongle.

Done all the steps in the guide.

Problem is that my iphone is not able to connect to dongle using bluetooth, and the red light is not working.

Hi,

Did you previously write anything onto it and have you done an erase? It could be that a UICR erase has been done accidentally.

Does it blink when you insert it and press the side mounted button?
