Hello Sascha,

It's a bit surprising that you ran into that exception (if you are using NCS 1.9). Would you mind providing me your project so that I can see if I can reproduce it here?

Regards,

Hello Sascha,

Right, sorry about that. I thought you were referring to the nRF5 SoftDevice for a second. The SD Controller however is supported.

What version are you using? 1.9.0?

Regards,

Elfving

I don’t believe that is accurate the Softdevice controller specifically says it supports the nRF5340 in its documentation. See here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/softdevice_controller/README.html

My question isn’t really about Rust since this error could and would occur in C as well. Really I just want help debugging that assertion, since there is no available information about what causes it

Hello Sascha, sorry about the delay

I believe the issue is related to you trying to use Softdevice on the nRF5340, while SD is only supported on our nRF52 series. The nRF5340 is multicore, which can be a lot to handle.

For more info on how to use Rust on our SoCs, see here.

I have a different issue now. I attempted to connect to the device using my phone, and it said negotiation failed. I expected that since I haven't added any code to handle connections. But now when I turn my phone's bluetooth on, I think it tries to auto-connect to my device. The SDC exception handler gets called with the data:

With file = "62", and line number "1846". Any info on what causes that error would be helpful, and what extra configuration I need to prevent that. I received no callback from sdc, besides the exception handler

In classic fashion, I managed to fix this soon after posting this question. I only had to use a little bit of Ghidra to get it done. It turns out that you have to manually configure the clock source manually. I also had the to switch the clock source to `MPSL_CLOCK_LF_SRC_MPSL_CLOCK_LF_SRC_SYNTH` .
