CC2652R: Current Consumption in Sleep

Hi Stefan,

Please follow the recommendations from SWRA625 and the Z-Stack User's Guide (Power Configuration section).  Power consumption are tested consistently every quarter to ensure they meet the expected criteria.  You will not need to use RF TI Driver commands but there are preprocessor configurations which should be considered.  I also recommend that you review the quarterly Z-Stack Release Notes (see Documentation Overview) for bugs which have been resolved.  If using a LAUNCHXL-CC26X2R1 to evaluate then make sure that the XDS110 jumpers are disconnected.

Can you elaborate how you measure power consumption and do you use TI  LAUNCHXL-CC26x2R to measure power consumption?

I connected battery and board through multimeter. No we are using custom board, bat it's not a hardware fault as we already had application on sdk 3_10_00_11 with consumption bellow 1mA in idle.

I already did everything that is mentioned in links that you provided but it didn't solve my issue.

Since you are using custom board, you should make sure unused pins are not configured as GPIO or other peripherals.

Please evaluate an out-of-box ZED switch example with the newest SIMPLELINK-CC13X2-26X2-SDK version and let us know whether the problem persists on your hardware.

I checked all GPIOs and they are not connected.

Also I tried to configure all as low outputs and it didn't change anything.  

Thanks for the update Stefan, please let us know when you've had time to evaluate my suggestion.

It's hard to do it because it's customized hardware with a lot of extern peripherals so we can't really evaluate out-of-box ZED example. We would need to configure ours peripherals and then I don't know would it be a valid test. I also forgot to mention that project is build on older version of IAR (8.32.3), maybe this is useful to you. Do you have some other advice how can I narrow possible problem.

Best regards,

Stefan

Basically, you need to configure used IO pins according to your schematics and set unused pins to PIN_UNUSED before you test power consumption.

It is important to match the IAR EWARM version with the recommendation from the SIMPLELINK-CC13X2-26X2-SDK Release Notes.  Migration Guides are available and there are instructions regarding Custom Hardware and Configuring the Board Files with SysConfig.  You may get further use out of the Debugging and Energy Trace User Guide.

I try to build project on ccs10.1.1 an the result was same.

Also I evaluate an out-of-box ZED switch example with the newest SIMPLELINK-CC13X2-26X2-SDK and I also got 3.3mA.

What can be the next step towards finding problem. 

What is worth mentioning is that we using CC2630 chip.

Best regards,

Make sure that CUI_DISABLE and Z_POWER_TEST are defined, referring to the Power Configuration section of the Z-Stack User's Guide.  You should have a LAUNCHXL-CC26X2R1 to test against, with the XDS110 jumper connections removed.  If the power consumption is not reduced then there is an issue with your hardware or test tools.  So far the CC2630 device has not been involved in this thread.
