EmberZNet Serial Protocol Frame—Version Command
Figure 10. EmberZNet Serial Protocol Frame - Version Command Example
1.
2.
Activate Slave Select (nSSEL).
Transmit the appropriate command:
?
?
?
?
?
?
?
0xFE : SPI Byte indicating an EZSP Frame
0x04 : Length Byte showing the EZSP Frame is 4 bytes long
0x00 : EZSP Sequence Byte (Note that this value should vary based upon previous sequence bytes)
0x00 : EZSP Frame Control Byte indicating a command with no sleeping
0x00 : EZSP Frame ID Byte indicating the Version command
0x04 : EZSP Parameter for this command ( desiredProtocolVersion )
0xA7 : Frame Terminator

7.
Wait for nHOST_INT to assert.
Transmit and receive 0xFF until a byte other than 0xFF is received.
Receive response 0xFE (a byte other than 0xFF ) and read the next byte for a length.
Stop transmitting after the number of bytes (length) is received plus the Frame Terminator.
Decode the response:

0xFE : SPI Byte indicating an EZSP Frame
0x07 : Length Byte showing the EZSP Frame is 7 bytes long
0x00 : EZSP Sequence Byte (Note that this value should vary based upon previous sequence bytes)
0x80 : EZSP Frame Control Byte indicating a response with no overflow
0x00 : EZSP Frame ID Byte indicating the Version response
0x04 : EZSP Parameter for this response ( protocolVersion )
0x02 : EZSP Parameter for this response ( stackType )
0x10 : EZSP Parameter for this response ( stackVersion , Note that this value may vary)
0x47 : EZSP Parameter for this response ( stackVersion , Note that this value may vary)
0xA7 : Frame Terminator
8.
Deactivate Slave Select.
