nRF52840 not advertising

[carl hong]

nRF52832 PCB designed by myself can work normally， change chip to nRF52840  not advertising(Phone can't scan)

[Ameer Usman]

The project folders for nRF52832 and nRF52840 are different (namely PCA10040 for nRF52832 and PCA10056 for nRF52840).

Make sure you have selected the correct project for each. Also try the debugger mode to exactly know where its getting stuck (if it is).

Also please mention how you are programming it and the SDK you are using. 

Correct me if I am wrong, you have a custom PCB for nRF52832 and you replaced the nRF52832 chip with nRF52840?

[carl hong]

I've select PCA10056, and application program normal work,only not advertising. i erase full chip by mdk and re download softdevice the problem remains

Have you tried debugging it to make sure there are no APP_ERROR_CHECK issues.

Also which compile are you using.

[carl hong]

no APP_ERROR_CHECK issues.

Are you using a modified program or one of the example codes? (First I would see to check if its working in the example codes like the ble_app_beacon before moving onto your own)
