IWR6843: Could not read all internal device temperature values.

Part Number: IWR6843

Hi,

I wanted to read internal device temperature of IWR6843. I used rlRfGetTemperatureReport() API to read it. But I could not read all temperature values like in xWR16xx. I tried to read through mmWave Studio also, but I am getting the same result.Only TX0-TX2 and PM can be read and rest of the temperature sensors always read zero.

Why is it so?

Is it possible to read all temperature sensors? If yes, then how?

    Hi Akshay,

    Thanks for your patience. As noted in the doxygen documentation for rlRfGetTemperatureReport() API, this is correct behavior for ES1.0 devices:

    file:///C:/ti/mmwave_sdk_03_01_01_02/packages/ti/control/mmwavelink/docs/doxygen/html/group___sensor.html#ga335113f6e1e6c260dcd03e03a0932a1b

    Or look at the function comment header (source for the doxygen) in C:\ti\mmwave_sdk_03_01_01_02\packages\ti\control\mmwavelink\src\rl_sensor.c.

    Thanks

    -Nitin
