Hi,
I need to put a ECU into diag mode and access private data in a secured session.I am supposed to send "10 03", then "27 03", receive a seed, and send the private key with "27 04".This is working fine with the terminal in CarScanner mobile app connected to a BT dongle, but when I try to use the OVMS box, the "10 03" is ok, but "27 03" return a serviceNotSupportedInActiveSessionerror. It is possible to start a secured / private session with the OVMS box ?
