CCS/LAUNCHXL-CC1352R1: low power mode for openthread

Hi,

Which SDK are you using?

Is the serial display being used?
If yes, this will cause additional current consumption. You can disable it by undefining BOARD_DISPLAY_USE_UART.

Toby

Please provide the LaunchPad jumper configuration and means by which you are measuring the current consumption.  http://dev.ti.com/tirex/content/simplelink_cc13x2_26x2_sdk_3_40_00_02/docs/thread/html/thread/application-development.html#low-power-operation

Hi,

I'm using latest one - 3.40.00.02.

Undefining  BOARD_DISPLAY_USE_UART didn't change anything :(

Hi Ryan,

I'm using energytrace and the board itself with no external measurement tools.

Currently I have following jumpers connected:

GND,5v,3v3,RXD,TXD,RST,TMS,TCK

AFAIK, that setting from the link is automatically done when you choose sleepy in syscfg.

Hi Marcin,

Here are some important instructions for optimizing EnergyTrace results:

You will need to have most jumpers disconnected and free run the MCU inside the debugger.

Ryan,

I followed all of those and I'm still getting same numbers :(

Have you joined this temp_sensor to a Thread network when you measure current?
If not, can you join it and again measure current?

I have joined and was receiving traffic on my border router while doing the test so everything worked as expected. Besides power usage ;)

One more thing happened. I was playing with the board and now I'm unable to start EnergyTrace. After pressing its button, a popup show with title "detecting EnergyTrace pod" and after it closes nothing happens. Programming and debugging works without any issue.
