I'm not able to share much information about our internal test setup for the Softdevice, unfortunately. But maybe this could be of interest: https://babblesim.github.io/. It's used in Zephyr here: https://github.com/zephyrproject-rtos/zephyr/tree/main/tests/bluetooth/bsim_bt

Ok, thank you :-) By the way, is there any blog entry on how you do testing for your stack? I would be interested in what kinds of tests you do, whether you have simulation etc,.... E.g. for FruityMesh, we have a simulator which kind of abstracts the BLE stack so we can test without hardware. I was always wondering if you have a hardware simulator to abstract all the timings, etc,....

Hello Marius,

There are no known problems with using the NRF_CLOCK_LF_SRC_SYNTH. The reason it is not listed as recommended has to with test coverage. We do not test it on the same level as we to with the crystal and RC oscillator.

Best regards,

Vidar
