> Stein's code from your branch works on my 2016 car with the TCU plugged in (I still have the TCU plugged in because the hands free microphone doesn't work when it's simply unplugged). I couldn't work out how to make the android app send an unlock command though, it would only let me lock the doors. Does the car have to signal it is locked before the app will invite you to lock it?
> I'll test on a 2012 car later today, but I'm pessimistic it will work on my car -- it needs to be woken up with a hardware signal rather than a CAN frame. The wakeup process changed to entirely CAN based in the 2013 model year and I've had reports some 2012 cars don't need the hardware wakeup. I haven't set up my OVMS v3 to make the necessary signal, so it won't be able to wake the car.
> On my 2016 model with the TCU connected, it locks the car multiple times. When I originally wrote the remote climate control and charge control code, I copied what the TCU sends, which is hte same message repeated for a second or so. Perhaps this is unnecessary on the 2016 cars, or on the lock signal?
> Stein do you have can bus captures of Nissan Connect doing the lock and unlock?

Nissan Connect does not support remote lock/unlock of doors on earlier than 2018 models.
