Research direction

Start by reviewing the documentation page that lists the Namimno OLED Flash 2.4 module as fully supported, then compare it with the reported EdgeTX, HDZero goggles, and backpack headtracking setup. Done should include an accurate support note describing the backpack limitation; any firmware fix would require reproducing the baud-rate behavior on the affected hardware.

Written by the indexing model from the issue text.

Description

Issue: When trying to setup headtracking with hdzero goggles and Namimno OLED elrs module, data is unable to make it to the aircraft. This page lists the module as "fully supported" and I think it should be changed to "partially supported" noting the backpack functionality is hampered.

setup: edgetx on jumper t18 with namimno oled flash 2.4, also tested with tx16s and a second identical module

reproduce: link goggles and module - this works fine and can send channel change commands to goggles and aircraft at the same time successfully. try to set up headtracking, and it never works. we tried updating everything twice, changing channels and mapping and everything.
See this link for everything we tried: https://discord.com/channels/596350022191415318/1370185589911060560 .

debugging: Nothing made it work except for a custom compiled version for the module that reduced the baud rate between the backpack and the main module . This made it work for a half a second, but nothing more.

suggested fix: probably nothing beyond updating the documentation. seems like few people have this module, with these goggles, and want to do wireless headtracking. However.... would be nice to have a fix, even if it's just adding extra error handling onboard, or slowing the baud rate a lot?

Thanks.
