Unlock, firmware, image, and parameter packets all have a fixed-size
|
|
64 bytes payload. Pings and acknowledgements have no payload. Pongs
|
|
may have a variable-size payload.
|
|
|
|
Even numbered packet types correspond to packets sent from the remote
|
|
controller to the device. Odd numbered packet types correspond to
|
|
responses. The device never initiates communication.
