IWRL6432: Uart port two-way transmission issue

Part Number: IWRL6432
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi,expert!

We try to run "Uart_read() or CLI_read()" commands when sensorStart run. But it cause program hang forever.

By rights, uart port should support two-way transmission even though sensor is running.

    Hello.

    It should if you are not using low power.  Low power causes the UART and other peripherals to turn off during the deep sleep period and turn back on after exiting deep sleep.  If you want to be able to send CLI commands during sensor execution, you will want to either keep UART on during deep sleep(option available in SysConfig under the power tab) or keep low power disabled.  You also should make sure that the commands/parameter values are valid and don't cause the program to error out; have you tried debugging the program once it crashes to see what might be the issue?

    Sincerely,

    Santosh

    Thanks! This issue has been solved. I follow your suggestion and remove "low Power Cfg 1", then Uart two-way trans works.

    Btw, i check sysconfig in the "Power" tab. I don't enable power policy. Its seems that even "low Power Cfg 1" have some effects on power policy disable mode!
