NOTE
Verify is the exclusive OR of Length, Command code, ID and Data.
All data are hexadecimal values.
For all commands received by the device, the protocol header needs to be changed to AB AB
and the protocol tail needs to be changed to CD CD when returning to the PC.
Precautions for control terminal programming: For the power-on command, AB AB 00 08 C1 15
00 00 01 BB BB DD CD CD are returned after the power-on action is executed; if the command
is not received, the power-on command needs to be sent again. After Android™ is turned on,
the PC will receive AB AB 01 04 A1 00 00 00 CD CD again, and then the PC can send a control
command to the device. If the correct command is not returned after any command is sent, the
command should be sent again at least after 500ms.
In Android standby state, the device only supports startup commands.
