ID). An Explicit TX 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). For unicast transmissions the 64 bit address field should be set to the address of the desired
destination node. The reserved field should be set to 0xFFFE.
The broadcast radius can be set from 0 up to NH to 0xFF. If the broadcast radius exceeds the value of NH then
the value of NH will be used as the radius. This parameter is only used for broadcast transmissions.
The maximum number of payload bytes can be read with the NP command.
Example: The above example sends a data transmission to a radio with a 64 bit address of
0x0013A20001238400 using a source endpoint of 0xA0, destination endpoint 0xA1, cluster ID
=0x1554, and profile ID 0xC105. Payload will be "TxData".

Frame-specific Data
Frame Type 30x11
Frame ID 40x01
Identifies this command for correlation to a later response
frame (0x8B) to this command. If set to 0, no response
frame will be sent.
64-bit Destination
Address
MSB 5 0x00
Set to the 64-bit address of the destination device. The
following address is also supported:
0x000000000000FFFF - Broadcast address
60x13
70xA2
80x00
90x01

14 0xFE
Source Endpoint 15 0xA0 Source endpoint for the transmission.
Destination Endpoint 16 0xA1
Destination endpoint for the
transmission.
Cluster ID
17 0x15
Cluster ID used in the transmission
18 0x54
Profile ID
19 0xC1
Profile ID used in the transmission
20 0x05
Broadcast Radius 21 0x00
Sets the maximum number of hops a broadcast
transmission can traverse. If set to 0, the transmission
radius will be set to the network maximum hops value.
Transmit Options 22 0x00
If the Transmit Options Bitfield is 0, then the TO
parameter will be used.
Bitfield:
bit 0: Disable ACK
bit 1: Don't attempt route Discovery.
bit 2: Enable Unicast NACK messages.
bit 3: Enable Unicast Trace Route messages.
All other bits must be set to 0.
