The most common setting for the CC1120 radio is the 50kbps, 2GFSK, IEE 802.15.4G mode. In this guide we will go through the necessary steps to configure the EFR32 radio to be able communicate with the TI radio.
The EFR32 side is ready, now let’s see the CC1120 settings.
To test the link, open a terminal program (TeraTerm or similar) and connect to the WSTK’s virtual COM port.
In the SmartRF Studio click switch to the Packet RX tab and click the Start button. Type ‘tx 10’ in the terminal program and the EFR chip will send out 10 packets. In the CC1120 device control panel you should see the packets arriving.
To test the other direction type ‘rx 1’. This will switch the EFR32 to receiving mode. In the control program of the TI chip click on the Packet TX tab. Untick the Add Seq. Number option, set Packet Count to 1, select Hex and type in the text box the content of the packet: ’01 23 45 67 89 AB CD EF’. Click on the Start button to send the packet. The received data will be displayed in the terminal program.
