Mark, Steve,
that's really a great relief!
I also doubt the fix will be backported. I tried applying the idf v3 commits involved in the fix you also commented on some weeks ago, but the
issue wasn't solved. I got the impression it's not an isolated issue of the driver. We should go idf-3.x anyway.
Regarding last hardware fixes, please don't forget…
5. Support active GPS antennas
I hope we can use the Wroom module.
Regards,
Michael
