CANbus switch state TX and switch feedback RX

General
1

Hello, as i didn’t find any good solution to Send and receive Canbus buttons im seeking for help.

What i need:
6 buttons (bitfield) transmit
6 button actual sate receive (bitfield)

whats problem right now:
if switch 1 toggled in realdash, byte 6 Bit (0, 1, 2, 3) will be 1
but in xml file its configured that byte 6 bit 0 should be 1.

if switch 2 toggled in realdash correct bit will be flipped but momentary and then self resets to 0.

Update well if i map one button it works, soon as i add another button in xml everything brakes.

for now there is no issue with receiving button state, only sending button state is problem.

I will run some tests on setting a bitfield with a button.
