NRF51 Dongle hangs at sd_rpc_open for both c & python code

Hi, Recently, I am playing around with the NRF51 dongle and trying to make it work as a BLE master.

However, when I run the sample code(e.g. advertising, multi-link .etc) from Nordic, the program hangs. And, this situation happens for both C Code and Python Code.

I used the "Python -m trace --trace main.py" to trace the error, and the result is attached below.

Thank you in advance. Jiadong.

Hi, Aryan. I have read the post before, but unfortunately, it did not work for me.
