Hi,
I've done the configuration settings according to SmartRF Studio. After the settings, a test data(0x55) is sent continuously to the tx fifo. At the receiver side, once the configurations are done, the status of the chip is being checked. But I found that the rx fifo is still empty from the returned status.

I'm now referring the code example provided by TI, I found that the tx mode is set after the data is written into the tx fifo. But I have not tried it, still reading the example given.

Thanks

Yes yes yes yes yes
I got it working!!!
With 500 kbps, the preamble has to be 8 bytes, sync word should be 30/32 and the packet length is not a concern. GDO2 is set to 0x06 for both tx and rx. GDO2 set high when sync word has been sent/received, it gets low when when the end of the packet is sent/received.

Preamble & Sync word??

I thought they are the same? But from the datasheet, both preamble and sync word must be there.
