CC3220SF-LAUNCHXL: TIDM-1020: CC3220SF LP Modifications?

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: CC2640R2F, CC3220SF, TIDM-1020


My hardware for TIDM-1020 is just CC3220SF LP + CC2640R2F LP + BOOSTXL-SENSORS BP. I read from the document guide that I need to remove and add complements at CC3220SF LP. But from my understanding this for interfacing the Touch Screen BP. So for my 3 hardware connections meaning I do not need to do that?

Post modified:

I flashed CC2640R2F LP with simple np from CC2640R2F SDK 3.10. I mount the CC2640R2F LP on top of CC3220SF LP and use SDK Explorer App to do BLE Provisioning and nothing is detected at app.


  • Hi Kel,

    If you are not using the LCD BoosterPack, you do not need to make the hardware changes to pins 57, 60, 64. You should comment out the demo_calibrate() function in thermostatInit() of demo_thermostat.c. You can also redefine TOUCH as (0) in wifi_thermostat_app.h.

    This thermostat demo requires a different CC2640R2F pin configuration due to all the stacked BoosterPacks. You can find instructions in section 3.2.5 of the design guide: I believe without the Kentec LCD, some of those pin conflicts are gone, so you may be able to make some adjustments.

    Best regards,


  • Hi Sarah,

    Thanks. My intention is just test the alexa wifi_thermostat example program with just CC3220SF LP + BOOSTXL-SENSORS BP. From my experience doing that after flashing I need to set SOP jumper to 001 and remove jumpers J2 and J3.

    I have not been successful connecting my setup to my wifi network using smart config.
