LP-CC1352P7: Issues using the upper range of 902-928 MHz with proprietary RF

Hi Mike,

Could you share the exact settings you used for each PHY?

Thanks Diego

Here's the primary one I'm using. 
In Proprietary 779-930 MHz, selected 1 Mbps, 350 kHz deviation 2 GFSK, 2.2. MHz Rx BW.
Then I changed the baud rate down to 500 kbps. Everything else is the same. 

This is the code I'm using to set frequency, which works anywhere from 902-920 MHz.

void radio_set_freq(double f) {

    rf_ctx.RF_cmdFs->frequency = (uint16_t)f;

    rf_ctx.RF_cmdPropRadioDivSetup->centerFreq = (uint16_t)f;

    rf_ctx.RF_cmdFs->fractFreq = 65536*(f - (uint16_t)f);

    /* Set the frequency. Now the RF driver powers the RF core up and runs the setup command from above.

     * The FS command is executed and also cached for later use when the RF driver does an automatic

     * power up. */

    RF_EventMask result = RF_runCmd(rfHandle, (RF_Op*)rf_ctx.RF_cmdFs, RF_PriorityNormal, NULL, 0);

    if ((result != RF_EventLastCmdDone) || ((volatile RF_Op*)rf_ctx.RF_cmdFs)->status != DONE_OK)

    {

        while(1);

    }

}

Here is my radio config

Hi Diego - was this enough information? Thanks!

Thank you Diego. I'll give it a shot!

I need to do quite a bit of surgery to go from rfc_CMD_IEEE_RX_t to rfc_CMD_IEEE_RX_ADV_t .
