Frame descriptions

Transmit Request frame - 0x10

Description
This frame causes the device to send payload data as an RF packet to a specific destination.
For broadcast transmissions, set the 64-bit destination address to 0x000000000000FFFF .
n
Address the coordinator by either setting the 64-bit address to all 0x00s and the 16-bit address
to 0xFFFE, or 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 helps
n
improve performance when transmitting to multiple destinations. If you do not know a 16-bit
address, set this field to 0xFFFE (unknown). If successful, the Transmit Status frame (0x8B)
indicates the discovered 16-bit address.
When transmitting to a broadcast address, the broadcast radius field can be used to determine how
many hops should be traversed.
You can read the maximum number of payload bytes with the NP command.

Identifies the data frame for the host to correlate with a subsequent
response. If set to 0 , the device does not send a response.
The 64-bit address of the destination device.

Reserved 64-bit address for the coordinator = 0x0000000000000000
Broadcast = 0x000000000000FFFF
MSB Set to the 16-bit address of the destination device, if known. If the
13 address is unknown or if sending a broadcast, set to 0xFFFE.
LSB
14
15 Sets the maximum number of hops a broadcast transmission can occur. If
set to 0, the broadcast radius is set to the maximum hops value.
