How about sending a null short packet, and a BTA after that. This
will
keep automatic TE mode in place, and we'll need to send 1 short
packet
instead of 2 long packets every frame.

To be honest, I didn't spend any time with this. True, sending a null
packet and BTA instead of the 2 long packets is possible. But probably
even better would be to track the TE status, and send a BTA only when
needed.

Right, if we maintain the TE status, we may not need to send a packet at all, so I guess we could stick with this for now, and remove it once we start maintaining the number of BTAs we have sent to the panel.
