programming autel or wegmann tpms sensors with custom protocol.

[mitchdetailed]

the goal : Custom tpms protocol with definable transmit rate of 2Hz when rolling or triggered , with a 30 second timeout to stop triggering. output struct to include tpms sensor id (4 bytes), pressure, temperature, and trigger type (rolling, pressure change, or handheld tool trigger)..

In short, tire-watch.fr has a custom transmit protocol that I cannot get a tool to create or replicate. sensors are marked up 500% over retail, and the receivers start at 2000 USD.

my goal is to build a clean slate receiver and custom protocol for an OE sensor, manufacturers have been of little help, as none of them seem to actually write their own software but purchase 3rd party license agreements to their tools..

has anyone successfully disassembled a tpms initial programming session to interpret the source code?
