Serial passthrough is broken #21114
Comments
Seems to be there for quite a while. With a JHEMCU GSF405A board, I was trying to flash a ELRS module, which is hardwired to SERIAL1, using passthrough, to no success. I though this is me who fails, but apparently not. |
@bugobliterator any update on this? |
Anything? |
Almost a year later, have any changes been done to the serial passthrough code? |
I've added this to the Copter-4.4 issues list so it won't be forgotten. I think serial pass through works in some cases at least because I used it a few weeks ago... so I suspect this issue is just for GPSs. |
Thank you, @rmackay9 ! |
So this really is a problem and we've got a fix for master (aka "latest") that we will backport to 4.4 for sure and possibly 4.3 if we ever do another release of 4.3. |
How do you feel about closing this now? |
I haven't tried it but I trust @tridge - happy to close |
