data
Data to be sent to the destination device.Up toNPbytes per
packet.
EOF 8-bit Checksum 0xFF minus the 8-bit sum of bytes from offset 3 tothis byte
(between length and checksum).
Transmit options bit field
The available transmit options vary depending on the protocol being used. Bitfield options can be
combined. Set all unused bits to 0.
0 Disable ACK [0x01] Disable acknowledgments on all unicasts.
1
Disable route
discoveries [0x02]
Disable Route Discovery on all DigiMesh unicasts.
2
Unicast NACK [0x04]
Enable unicast NACK messages on DigiMesh transmissions
When set, a failed transmission will generate a Route Information -
0x8Dframe for diagnosis.
3
Unicast trace route
[0x08]
Enable a unicast Trace Route on DigiMesh transmissions
When set, the transmission will generate a Route Information -
0x8Dframe.
5 Reserved <set this bit to 0>

b’00 = If BR = 0 then packet type will be Point-multipoint otherwise
it will be DigiMesh
b’01 = Point-multipoint [0x40]
b’10 = Repeater mode, Directed Broadcast [0x80]
b’11 = DigiMesh—not available when BR = 0 [0xC0]
Examples
Each example is written without escapes (AP=1) and all bytes are represented in hex format.For
brevity, the start delimiter, length, and checksum fields have been excluded.
64-bit unicast
Sending a unicast transmission to a device with the 64-bit address of 0013A20012345678 with the
serial data "TxData". Transmit options are set to 0, which means the transmission will send using the
options set by the TO command.
The corresponding Transmit Status - 0x89response with a matching Frame ID will indicate whether
the transmission succeeded.
