CC2640R2F: HS Modulation on the CC2640R2

Daniel Nelson13

Part Number: CC2640R2F

Per the related thread, the CC2640R2 should be capable of HS modulation. I successfully run the setup command on my 2640 LaunchPad, and I've tried issuing the HS mode TX, but CMDSTA is returning "unknown command"

(from my code)

Transmitting command number 0x3841
Doorbell returned (0x82) took 47

Is there any special initialization I need to do?

Daniel,

Please find this simple packet error rate example as a demo of how to use the 5mbps mode on CC2640R2, all the magic PHY stuff is actually already inside the ROM of the device so therefore all this code does is wake it up and run it.

rfPacketErrorRate_CC2640R2_LAUNCHXL_tirtos_ccs_v2.30.00.28.zip

I tested this using the Simplelink SDK that is available online today (v2.30).

You need to start up a terminal program at 115200bit/s (8N1) and then you can see the results, there is unfortunately no blinking LEDs.

Regards,

Cool, got the code running. Turns out the missing bit in my code was that PRCM_O_RFCMODESEL needs to be 0x3 for HS mode, not the default 0x0. Now the radio is accepting my commands. Thanks much!
