CCS/CC1350: Receive Sub1 packets in custom cc1350 module

Hi,

The project that I'm currently working on is to receive sub1 packets in cc1350. Earlier we had worked with cc1100. Now we have to replace cc1100 with custom cc1350 module. I tried sample tx rx projects found in the Resource explorer and it was found working ( I tried rFPackettx and rFPacketRx projects). But upon looking, i found these projects were using 868MHz. In my case, the packets are being transmitted at 915 MHz. I also came to know that, in order to change frequency, one is supposed to edit smartrf_settings file. I experimented with that, but still i couldn't receive any of the packets. What all things am i doing wrong? Can anyone please point me in the right direction.

Hi, your 'new' settings can be generated by the application SmartRF Studio.
Set the appropriate settings in the GUI (and verify Tx/Rx), click on Code export and copy the settings into your smartrf_settings files.

There is a training handling such operations, have a look at:

Thanks for the reply. My intention is to replace cc1100 with cc1350. So for the RX, i changed the frequency (915MHz), symbol rate (38kbps) and other values for cc1350. Still it's not working. Are there any other values I should change for this to work? Also, what is this "sync word"? .
