Which products support the ATPTA command

[stumo]

I'm looking for K-line interface hardware for my Arduino project. The ECM I'm connecting to on k-line requires a 1ms shorter low init pulse than the SAE specified 25ms to enter KWP fast init ISO14230-4 mode. So that rules out most of the cheap BT adapters out there because they have a fixed 25ms pulse.

So I would like to know which Freematics products support the ATPTA command so that I can generate a 24ms low pulse for KWP init. The ECM fully supports KWP fast init ISO14230-4, except for that 24ms low pulse requirement.

Unfortunately our products have no better support for K-line and we are not looking to improve it since the protocol is shifting out.
