@saurabhst I could not reproduce with ToT can you pull and retry ? If you still get this please give me some more info. With this log it seems that right after boot up it hard faults. I was able to do the full commissionning flow.

We're in progress of reviewing older issues. Is this still an issue given how old the SDK this was tested against? Please re-open if so. Thanks!
