Communication dump with notes

Firmware version: 6.7Q
Magic: F294
UID: 0A00002802C4EB
This seems to work differently from what we've seen on STC10/11/12 series with
firmware 6.2/6.5.

* MCU first sends an ACK packet (0x80),
which needs to be replied to with the same ACK (0x80) by the host.
after that host needs to pulse (send 0x7f until reply) again
* STC software then adjust the frequency of the RC, after that the handshake
is done.

instead of testing it like in earlier firmware.
