IWRL6432BOOST: How the app do Device reset when sending again another cfg file?

Part Number: IWRL6432BOOST

Hi

I tried the Low_power_visualizer_5.2.0.2, for resending the config files.
It does the Device reset through software.
How does it do that?

Regards
Aditya

    As you can see in the cfg files, there is a CLI command called sensorStop. This command stops the sensor and allows it to receive another configuration file.

    Hi
    But the sensorStop command is not supported when lowPowerCfg is 1.

    Then how does the app tackle this?

    Hello,

    Yes, you are right. As the documentation says, you cannot use sensorStop when lowPowerCfg is enabled. This is because when you are in low power mode, after the device finishes handling data within a frame, it immediately goes into the low power sleep, leaving no time to read a CLI command. Then the device wakes up to collect more data again. 

    The way the Low Power Visualizer manages this is by utilizing the XDS110 to issue a device reset. Please refer to this document: https://www.ti.com/lit/ug/sprui94/sprui94.pdf, section 3.7.3.1, to see how to do this yourself.
