11 – Single channel operation on Channel 3; 
 
Default Configuration on Reset: 00. 
 
3.4  Command GETSTATE
  
Write COMMAND_GETSTATE (0x02) to the serial interface of the Module. On receiving 
the command, the Module will return its current state | RSP_SUCCESS. The command 
does not have a failure response. State IDLE is denoted by 0x01 for normal operation; and 
State TEST (Section 3.24) is denoted by 0x11 for a special radio test mode. 
 
3.5  Command BROADCAST 
Write COMMAND_BROADCAST (0x03) to the serial interface of the Module. On 
receiving the command, the Module will return COMMAND_BROADCAST | 
RSP_SUCCESS (0x83) if there is available TX buffer space in the Module and the network 
address is valid. Otherwise the Module will return COMMAND_BROADCAST | 
RSP_FAIL (0x03). 
 
On receiving the COMMAND_BROADCAST | RSP_SUCCESS (0x83), the Host must 
write the packet for broadcasting to the Module serial interface. 
BYTE 0: Length of Transferring N (N must be: > 0 and < 122) 
BYTE 1: Broadcast Sequence Number 
BYTE 2 –N: Payload of Broadcasting Packet 
 
Broadcast packets do not have an ACK mechanism in the protocol, therefore successful 
packet delivery is not guaranteed at the wireless link level. 
                                               
3.6  Command UNICAST
  
Write COMMAND_UNICAST (0x04) to the serial interface of the Module. On receiving 
the command, the Module will return COMMAND_UNICAST | RSP_SUCCESS (0x84) if 
there is available TX buffer space in the Module and the network address is valid. Otherwise 
the Module will return COMMAND_UNICAST | RSP_FAIL (0x04). 
On receiving the COMMAND_UNICAST | RSP_SUCCESS (0x84), the Host must write 
the packet for unicasting to the Module serial interface. 
BYTE 0: Length of Transferring N (N must be: > 2 and < 116) 
BYTE 1-3: Address of the Unicast Destination 
BYTE 4: Unicast Sequence Number 
BYTE 5 –N: Payload of Unicasting Packet
