CC2652R: how to make cc2652R sleep and wake up? is there any example or tutorial?

All the examples in SDK with prefix zed_ such as zed_sw can support cc2652R sleep and wake up automatically.

Are you planning to use a given stack or something else? 

It would be easier to answer your question if knowing more about how you plan to use the chip since the details will be slightly different depending on the software running. 

hi,

thanks for your answer.

but i do not known how to make it sleep with zed_ examples.i can not find the code of the sleep function.

zed_ examples would go to sleep automatically when there is nothing to process. Application developer doesn't have to do anything.

What do you mean define your own sleep function?

hi

in the sdk of zed_light example,the power consumption of the circuit board is always 2mA.so it doesn't feel like the cpu is sleeping.

Do you measure power consumption on LaunchPad? If so, do you remove all jumpers on LaunchPad?

hi

i  just want it to sleep under certain conditions.

thanks

Hi li,

What exactly are you trying to accomplish?  You can set timers to determine wake-up times or invoke active mode through peripheral interrupts (UART, pin, etc) but it would be inefficient for a ZED to be always active since it does not need to always be aware of incoming packets to route.  You can disable the USE_ZCL_SAMPLEAPP_UI and BOARD_DISPLAY_USE_UART inside Project Properties -> Build -> ARM Compiler -> Predefined Symbols for better power savings.  You can reference the Power Configuration section of the Z-Stack UG as well: http://dev.ti.com/tirex/explore/content/simplelink_cc13x2_26x2_sdk_4_10_00_78/docs/zigbee/html/zigbee/power_configuration.html#power-configuration

Hi Ryan,

i just want to make a low-power application and add other drivers.but i don't where to start.

in sdk of zed_light,i cancel USE_ZCL_SAMPLEAPP_UI and BOARD_DISPLAY_USE_UART  at your suggetions. the current of the cc2652 module is always 0.1mA.i don't known how to make it lower and wthat is lowest limit.

Best Regards,
