802.15.4 Send Data example for mbed XBeeLib By Digi
Description
This example shows how to send data to a remote XBee802 module.
The application creates a message for a remote XBee module.
This library encodes and sends it to the local XBee module through the serial port. Then the local XBee module sends the packet to the remote XBee module through the air.
The example shows how to send both unicast and broadcast messages.
See Sending data to another module chapter for more information.
Common Setup
Make sure you have a valid Example Common Setup
Example Setup
XBee modules
To evaluate the 16-bit addressing mode you have to configure the local XBee module and the remote XBee module with unique values... for example 0x1111 for the local and 0x2222 for the remote.
Application
Broadcast messages doesn't require any configuration, but for the unicast messages you have to configure:
- The remote device 64-bit address by customizing the REMOTE_NODE_ADDR64_MSB and REMOTE_NODE_ADDR64_LSB defines with the remote XBee module 64-bit address.
- The remote device 16-bit address by customizing the REMOTE_NODE_ADDR16 define with the remote XBee module 16-bit address.
Running the example
Build and deploy the example to the mbed module.
Reset the mbed module so the example starts. You should see the example debug information through the debug interface configured in the 'Local Setup' chapter.
The application will first send a broadcast message and finally a couple of unicast messages to the configured remote XBee module (first using 64-bit addressing mode and then using 16-bit addressing mode).
Verify that the remote XBee module is receiving the frames by accessing the "Console" tab of the X-CTU. You should see there the broadcast and unicast messages.
