uAEFI - Serial over WIFI for TS coms

[MWP]

Hi all,

I'm trying to use a ESP32 (wifi to serial bridge) on the 2nd calibration channel on a uaEFI.
It all looks good, but when i hit the TS coms "test port" button, the uaEFI shuts down (im not sure what its doing exactly, but it cuts V33_SWITCHABLE/V33_EXT).

I've confirmed the ESP32 wifi-serial bridge works fine (first connected to a TTL USB-serial interface, and send/rec data from a PC).

The ESP32 and "Calibration Secondary Channel" are both set to 115200 baud. TX is PD5, RX is PD6.

I've looked at the TX/RX coms with a DSO, when I do "test port", there is data, but i dont know if it's the correct data or not (does anyone know what data is sent by TS to check coms?).

Is there anything im obviously missing here?

Thanks.

If you power ESP32 from uaEFI may be you should apply this fix https://github.com/rusefi/uaefi/?tab=readme-ov-file#bluetooth-power-issue-fix

Thanks, i'll do that tomorrow.

I don't think it'll fix this problem though. It only happens when data is sent from TS.

Are you using latest RE firmware?
There was uart fix maybe month ago.
Usefi was rebooting by WD because of stuck in uart irq.
Now this should be fixed in master.

I think that was it.
I updated to yesterdays nightly, and now TS coms via wifi are working.
(i havent added a cap)

Thankyou

Great, can you post some more details? What ESP32 module are you using? What firmware are you using?
