CC2640R2F RF turning time

Other Parts Discussed in Thread: CC2640R2F

I am using CC2640R2F to measure RSSI values on  several frequency channels, what I did: 

1.  Set frequency by  RF_postCmd;

2. Using RF_postCmd with Receiver Test Command  to set radio;

3. read RSSI by RF_getRssi ;

4. cancel the Receiver Test Command by  RF_cancelCmd;

5. go back to step 1 for another frequency ; 

I found that frequency setting, mode set and cancel took quite long time, like several hundred microseconds, I need to speed  up the measurement, is there any way to do that?

Thank you for your help!

    Hi Michael,

    A couple hundred microseconds makes sense given a 24 MHz radio frequency and accounting for time needed to post commands, dispatch RF events, stop/start clocks accordingly, and change/validate the new frequencies or modes of operation.  Your observation is within expectations and there is not a recommended method for bypassing the RF APIs.
