Example: The example above shows how to send a transmission to a module where escaping is disabled
(AP=1) with destination address 0x0013A200 40014011, payload "TxData0A". If escaping is enabled (AP=2),
the frame should look like:
0x7E 0x00 0x16 0x10 0x01 0x00 0x7D 0x33 0xA2 0x00 0x40 0x0A 0x01 0x27
0xFF 0xFE 0x00 0x00 0x54 0x78 0x44 0x61 0x74 0x61 0x30 0x41 0x7D 0x33
The checksum is calculated (on all non-escaped bytes) as [0xFF - (sum of all bytes from API frame type
through data payload)].
Explicit TX Request
Frame Type: 0x11
Allows application layer fields (endpoint and cluster ID) to be specified for a data transmission. Similar to the
TX Request, but also requires application layer addressing fields to be specified (endpoints, cluster ID, profile

Start Delimiter 00x7E
Length
MSB 1 0x00
Number of bytes between the length and the checksum
LSB 2 0x16
Frame-specific Data
Frame Type 30x10
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
90x40
10 0x0A
11 0x01
LSB 12 0x27
Reserved
13 0xFF
Set to 0xFFFE.
14 0xFE
Broadcast Radius 15 0x00
Sets maximum number of hops a broadcast transmission
can occur. If set to 0, the broadcast radius will
be set to the maximum hops value.
Transmit Options 16 0x00
If the Transmit Options Bitfield is 0, then the TO
parameter will be used.
Bitfield:
bit 0: Disable ACK
bit 1: Disable Route Discovery
bit 2: Enable Unicast NACK messages.
bit 3: Enable Unicast Trace Route messages.
bits 6,7: b’01 - Point-Multipoint
b’10 - Repeater mode (directed broadcast)
b’11 - DigiMesh (not available on 10k product)
All other bits must be set to 0.
