No response from Softdevice

Sebastian Wantia

I have a have a problem which i cant fix. I'm trying to run the Heart Rate project, but the soft device hangs up (at this line: sd_app_evt_wait(); ) The software jumps not in the error Handler and is not reacting in any kind (Buttons, Advertising)

The blinky example worked fine. Only the Softdevice makes some problems.

My hardware: nrF 6310 Board PCA1005 nrf51822 daughter board J-Link Lite Cortex M

My installed software: KEIL-MDK 5 SDK: V5.0.0.34603 Softdevice: 6.0.0-5.beta (The nrfGo Studio says unknown firmware )

Many thanks in advance

    Hi Sebastian,

    Did you see any LED turn on ? It's not easy to debug when the softdevice is running, you will most likely stuck at sd_app_evt_wait() and a hardfault after that because the softdevice is precompiled and is not halted by the debugger.

    What you can do is to add a breakpoint into app_error_handler() and trace back the line and file name if something causes an error. Also if you use PCA10005, please don't forget to connect the SMA antenna.
