The code export window can be used to export code structures to configure the device and is useful when you want to generate new PHY settings to integrate into an embedded project or change PHY settings for an existing code example.

The rfPacketTxGenFSK example from the TRX plugin runs default the 2gfsk50kbps PHY, but can easily be changed to run with a general purpose PHY generated using SmartRF Studio.

1. Start by importing the rfPacketTxGenFSK from the TRX plugin to your example folder.

   Example: C:\CodeExamples\TRX\CC140xP

2. Under PHY SELECTION in SmartRF Studio (see Figure 3-1).
   1. Select the General purpose GFSK.
   2. Select Create custom PHY, and implement any necessary changes (for this example we are changing the sync word).
   3. Press the "Code Export" button.
