BLE App UART on PCA10056 not working?

[Meriba]

I'm using the original BLE App UART from nRF5_SDK_14.0.0 on a PCA10056 Board. The board is advertising, but if I want to open a BLE peer-to-peer connection, than the application stops in the app_error_fault_handler.

If i use the same BLE App UART project from the SDK on a PCA10040 Board than it works.

Does anyone know what the problem could be?

PCA10056 is for nRF52840 and PCA10040 is for nRF52832. Are you sure you are uploading it to the correct board?

I addition to superpak's comment; what softdevices are you using?

[Meriba]

I have uploaded the PCA10056 build from the project on a development board with nRF52840 in combination with the Softdevice S140 5.0.0-2.alpha.

[Joakim Jakobsen]

That should be correct. What are you using to connect to your PCA10056 Board? If you are using a smartphone, which phone are you using?

[Meriba]

I'm using an Iphone 7 with iOS11.0.3, the same smartphone like in my test with the PCA10040, which will work fine.
