Frame descriptions User Data Relay frame - 0x2D
Digi XBee® 3 Zigbee® RF Module

Example use cases
These examples show how to use this frame.
n You can use the frame to send data to an external processor through the XBee UART/SPI via
the BLE connection. Use a cellphone to send the frame with UART interface as a target. Data
contained within the frame is sent out the UART contained within an Output Frame. The
external processor then receives and acts on the frame.
n Use an external processor to output the frame over the UART with the BLE interface as a
target. This outputs the data contained in the frame as the Output Frame over the active BLE
connection via indication.
n An external processor outputs the Frame over the UART with the Micropython interface as a
target.
Example
This example frame could be used to send the message “Relay Data” to the MicroPython interface
using API mode 1 (AP = 1).
