Frame descriptions
64-bit Transmit Request - 0x00
Response frame: Transmit Status - 0x89
Description
This frame type is used to send serial payload data as an RF packet to a remote device with a
corresponding 64-bit IEEE address.
Note This frame format is deprecated and should only be used by customers who require
compatibility with legacy Digi RF products. For new designs, we encourage you to use Transmit
Request frame - 0x10 to initiate API transmissions.
Format
The following table provides the contents of the frame. For details on frame structure, see API frame

Frame ID
Identifies the data frame for the host to correlate with a
subsequent response.
If set to 0, the device will not emit a response frame.
