CCS/CC3220SF-LAUNCHXL: TIDM-1020: startup issue

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: BOOSTXL-K350QVG-S1

Tool/software: Code Composer Studio

I plan to utilize thermostat example (https://www.ti.com/tool/TIDM-1020) as a starting point for my project. However after significant time spent on trying to start it up I did not manage to see any results.

As a hardware I use CC3220SF-LAUNCHXL  together with BOOSTXL-K350QVG-S1.

I also installed SDK’s with proper versions, as stated in https://www.ti.com/lit/ug/tidudq7a/tidudq7a.pdf?ts=1605789187766&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FTIDM-1020 .

Unfortunately I am not able to perform provisioning of the device. The Mobile app for android notifies that it cannot detect the device or that device supports only legacy provisioning.

In case of configuration via touch display, it is also impossible, because the Display remains inactive. From what I have seen in the debug, the FW waits for the calibration procedure to be conducted.

If there is a specific way i should run such HW configuration or am I missing something?

Best Regards,

Jerzy

    Hi Jerzy,

    Since the TI Design software is based on an old SDK version, but the Wi-Fi Starter Pro mobile app have updated since then on the Apple and Google stores, they may not be compatible anymore. That is a limitation of the demo mobile app. You can test provisioning with the mobile app using any demo in the latest SDK. My suggestion to continue with this TI Design is to use the BLE provisioning or directly adding a a WLAN profile using the built-in HTTP server. Connect to the CC32xx's AP network (the SSID should be mysimplelink-thermostat) and use any internet browser to go to mysimplelink.net/settings.html or 10.123.45.1/settings.html

    Did you complete the required hardware modifications in section 3.4.1 of the design guide? This is linked from the AWS TIDUDQ7 document: https://www.ti.com/lit/tiduec9. The explanation for why these modifications are required for the resistive touch functionality is in section 2.3.1.1.

    Keep in mind the resistive touch is not very accurate and was added for demo purposes. For a real application, I suggest looking at our capacitive touch solutions instead.

    Best regards,
