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
For unicast transmissions, set the 64 bit address field to the address of the desired destination
n
node.
Set the reserved field to 0xFFFE.
n
Query the NP command to read the maximum number of payload bytes.
n
You can set the broadcast radius 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.
You can read the maximum number of payload bytes with the NP command.
