Other Steps to Reproduce

on the first boot of the firmware and on subsequent reboots

I have checked existing issues, online documentation and the Troubleshooting Guide

• I confirm I have checked existing issues, online documentation and Troubleshooting guide.

please add minimal example that we can compile and run. We do not have reports for C3 having issues thus far.

Cannot reproduce. Perhaps you are out of memory.

memory available just before calling .connect() is 207,696 bytes

In the meantime i've uploaded the full firmware code here:

you can download and try it for yourself.
