The checksum is calculated (on all non-escaped bytes) as [0xFF - (sum of all bytes from API frame type through
data payload)].
Example: Send a transmission to the coordinator without specifying the coordinator's 64-bit address. The API
transmit request frame should look like:
0x7E 0x00 0x16 0x10 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xFF 0xFE 0x00 0x00 0x54
0x78 032 0x43 0x6F 0x6F 0x72 0x64 0xFC
Where 0x16 = length (22 bytes excluding checksum)
0x10 = ZigBee Transmit Request API frame type
0x01 = Frame ID (set to non-zero value)
0x0000000000000000 = Coordinator's address (can be replaced with coordinator's actual 64-bit address
if known
0xFFFE = 16-bit Destination Address
0x00 = Broadcast radius
0x00 = Options
0x547832436F6F7264 = Data payload ("Tx2Coord")
0xFC = Checksum
Explicit Addressing ZigBee Command Frame
Frame Type: 0x11
Allows ZigBee application layer fields (endpoint and cluster ID) to be specified for a data transmission.
Similar to the ZigBee Transmit Request, but also requires ZigBee application layer addressing fields to be
specified (endpoints, cluster ID, profile ID). An Explicit Addressing Request API frame causes the module to
send data as an RF packet to the specified destination, using the specified source and destination endpoints,
cluster ID, and profile ID.
The 64-bit destination address should be set to 0x000000000000FFFF for a broadcast transmission (to all
devices). The coordinator can be addressed by either setting the 64-bit address to all 0x00s and the 16-bit
address to 0xFFFE, OR by setting the 64-bit address to the coordinator's 64-bit address and the 16-bit address
to 0x0000. For all other transmissions, setting the 16-bit address to the correct 16-bit address can help improve
performance when transmitting to multiple destinations. If a 16-bit address is not known, this field should be
set to 0xFFFE (unknown). The Transmit Status frame (0x8B) will indicate the discovered 16-bit address, if
successful.
The broadcast radius can be set from 0 up to NH. If set to 0, the value of NH specifies the broadcast radius
(recommended). This parameter is only used for broadcast transmissions.
The maximum number of payload bytes can be read with the NP command. Note: if source routing is used, the
RF payload will be reduced by two bytes per intermediate hop in the source route.
