comment from Markus
possible but CAT did not work with out the APP running.
so my current estimate is that the APP controls the MUX chip and with out it the CAT from USB is not routed correct.
Intressting too is that CAT from the SoC / Linux is possible too so the SoC may has a Serial to the same MUX chip but I did not find the connection yet. 160+ connections on the SoC module is a loot 😉
