1. To open the serial forwarder on testbed, run the command
'forwarder.py -2 -a telosb'
2. We can get the packet format used by the serial forwarder in 'tospacket.py':
- 0: Delimiter (0x7E)
- 1: Protocol: ACK (0x43), PACKET_ACK (0x44) or PACKET_NOACK (0x45)
- 2: Sequence number (omitted if protocol is PACKET_NOACK)
- 3: Packet type (0x00, omitted if protocol is ACK)
- 4: Destination high byte (omitted if protocol is ACK)
- 5: Destination low byte (omitted if protocol is ACK)
- 6: Source high byte (omitted if protocol is ACK)
- 7: Source low byte (omitted if protocol is ACK)
- 8: Payload length (omitted if protocol is ACK)
- 9: Destination PAN group (omitted if protocol is ACK)
- 10: Packet AM type (omitted if protocol is ACK)
- 11 .. n-4: Payload (omitted if protocol is ACK)
- n-3: CRC-16 low byte
- n-2: CRC-16 high byte
- n-1: Delimiter (0x7E)
