Hi, I get the above mentioned same error. all my init function passes but when it is sd_app_evt_wait() the code hangs. I tried sniffing the packets using Ti packet sniffer but no packets were observed.

I use a NRF51822 chip along with eclipse and GNU GCC compiler for arm

@Sebastien: Most likely the chip was advertising. What master did you use to scan for advertising package? Would you be able to scan for any other BLE device ? If you use Master Control Panel, could you take a screenshot ?

Regarding nRFGo Studio's unknow ID, it was because the current nRFGo studio haven't been updated with new Softdevice. So it doesn't recognize the S110 softdevice v5.2.1 and v6.0.0 ID.

Thank you for the quick answer! Yes the LED_0 is on. The breakpoint in the app_error_handler() was never called. The SMA antenna is connected. What about the the nrFgo Studio, the software says unknown Firmware and hardware id?

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.
