LPSTK-CC1352R: Multisensor example does not show temperature, illumination

Part Number: LPSTK-CC1352R

Hello!

I have LPSTK with CC1352R1F3 revision E. With Btn-1 + power default multisensor image works as expected. Next I import multi_sensor_CC13X2R1_LAUNCHXL_ti_rtos_ccs example project from simplelink_cc13x2_26x2_sdk_5_10_00_48, build it and OAD the image. Device does reboot, advertises as Multi sensor, I can connect to it, but once connected, Simple link starter app on my phone shows readings from humidity sensor, accelerometer, battery level, button state and LED controls (operational), but no temperature and illumination sensors. Service explorer lists generic access, GATT, device information, OAD service, humidity service, ProjectZero LED and switch services, battery and accelerometer services, but no temperature and illumination services.

I was closing simplelink starter app and turned off bluetooth on my phone after OAD.

Please help to fix this situation.

Thank you.

    I have connected my LPSTK to XDS110 emulator on CC1352R1 launchpad. I am trying to step multi sensor application and monitor output on UART. When factory image is executed, everything is just fine. When I load and run multi sensor example built on my own, I see messages that HDC sensor init failed, temperature profile init failed, like here

    I have traced down to

    io.hdc.handle = HDC2010_open(BOARD_HDC2010, *pI2cHandle, &hdc2010Params);

    line in hum_profile.c and yes, return handle is NULL, but I can't tell what is actually wrong.

    Please advise.

    okay, broken out of the box demo is known issue. rolling back to simplelink sdk 3.40.00.02 fixes example.

    I couldn't believe I am writing this...
