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

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

Hi,

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: http://www.ti.com/lit/tiduec9. I believe without the Kentec LCD, some of those pin conflicts are gone, so you may be able to make some adjustments.

    Best regards,

    Sarah

    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.
