Digi XBee SX 868 - Data Transmission Frames

Frame descriptions Transmit Request - 0x10
XBee® SX 868 RF Module User Guide

Transmit Request - 0x10
Response frame:Extended Transmit Status - 0x8B
Description
This frame type is used to send payload data as an RF packet to a specific destination. This frame type
is typically used for transmitting serial data to one or more remote devices.
The endpoints used for these data transmissions are defined by the SE and EP commands and the
cluster ID defined by the CI command—excluding 802.15.4. To define theapplication-layer addressing
fields on a per-packet basis, use theExplicit Addressing Command Request - 0x11instead.
Query the NPcommand to read the maximum number of payload bytes that can be sent.
64-bit addressing
n
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
node
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
format.
Offset Size Frame Field Description
0 8-bit Start
Delimiter
Indicates the start of an API frame.
1 16-bit Length Number of bytes between the length and checksum.
3 8-bit
Frame type Transmit Request - 0x10
4 8-bit
Frame ID Identifies the data frame for the host to correlate with a
subsequent response frame.
If set to 0, the device will not emit a response frame.
5 64-bit
64-bit
destination
address
Set to the 64-bit IEEE address of the destination device.
Broadcast address is 0x000000000000FFFF.
13 16-bit
Reserved Unused, but this field is typically set to 0xFFFE.
15 8-bit
Broadcast
radius
Sets the maximum number of hops a broadcast transmission
can traverse. This parameter is only used for broadcast
transmissions.
If set to0—recommended—the value of NHspecifies the
broadcast radius.
