3. Communication Protocol
The module is used as a slave device. The Master device sends relative commands to control it.
The CMD sent by the master and the ACK signal returned by the module.
Command interface: UART (Universal Asynchronous Receiver Transmitter)
Default Setting is : 115200BPS ,1 start-bit ,1 stop-bit ,no check bit

3.2 Classify of communication packet

3.2.1 Command packet
Command Packet is the instruction from Host to Target (ADST11SD3xx),
Total length of the command packet is 24 Bytes
3.2.2 Response packet
Response packet is result of execute command packet, from Target (ADST11SD3xx) to Host,
Total length of the command packet is 24 Bytes
3.2.3 Data Packet
When length of Command Parameter or Data is larger than 16 Bytes, Utilize Data Packet
to transmit block Data, the maximum length of Data Packet is 512Bytes
