mestrode / lin-transceiver-library Goto Github PK

Hello,

I'm using this library (actually my fork just to adjust a couple of things) to try and control a truma combi d (i.e. to emulate a CP plus control panel).
I adapted this code https://gitlab.womolin.de/public-repository/esp32-tin-master and I'm using the connection described here https://github.com/danielfett/inetbox.py
Additionally, since this is a master, I connected the INH and LIN terminals of the breakout board (as per the datasheet, the board has already a resistor and a diode between the INH pin and the INH terminal) and an output of the esp32 to the SLP terminal.
Unfortunately I don't get any answer from the truma. I see the echo of what I send (only if I supply 12V to the board) but nothing else.
I'm wondering if the board is faulty, I connected it wrong or I didn't adapt the software correctly.
I also tried the origina repo (after adapting it from the original esp8266 to the esp32) with no success either (and since it doesn't control the state machine I think it's expected, however the inetbox.py repo doesn't control it either and there are people using it).
Any hint?
