CC2642R: There are no selectable modes for the module in the software.

Part Number: CC2642R

As we can observe in the software, the module currently has no low-power mode; moreover, the module in the software cannot enter any mode at all, and it is now consuming excessive power.

    Hello,

    Thanks for reaching out. Seems you are not entering standby in between what seems to be advertisements or connection events as you pointed out. What SDK version are you using, is the SW you are running out of the box, if not what modifications have you done? Are you using a launchpad or your own custom board? 

    BR,

    David.

    1. Thank you for your reply.


      The SDK version in use is: simplelink_cc13x2_26x2_sdk_3_10_00_53It is modified based on the sample project corresponding to the CC2642R1 LaunchPad, and the directory path is: C:\ti\simplelink_cc13x2_26x2_sdk_3_10_00_53\examples\rtos\CC26X2R1_LAUNCHXL\ble5stack\simple_peripheral_oad_offchipThe current power configuration item is functional.

      When enabled, the current ranges between 0.04-0.4mA and 0.8-1.1mA at times; when disabled, it stays at 4.5mA

    Hello Jerry,

    Allow me to look into this. Any chance you can try to reproduce in a TI Launchpad as it will be hard for me to consider all the HW dependencies. Has it worked well before with another SW (or another board same SW). I ask because I see that you are not using the latest SDK (which I would also suggest). 

    However, I want to first understand why you are not setting the standby policy to true? If not, then the power driver will not put the device into low power mode (standby) when possible, therefore increasing the power consumption.

    BR,

    David.
