CC26xx power management for UART Deiver question

Since you don't define hwAttrs in your project, you can use the following defines in PowerCC26XX.h instead of hwAttrs->powerMngrId.

#define PowerCC26XX_PERIPH_GPT0 0
#define PowerCC26XX_PERIPH_GPT1 1
#define PowerCC26XX_PERIPH_GPT2 2
#define PowerCC26XX_PERIPH_GPT3 3
#define PowerCC26XX_PERIPH_SSI0 4
#define PowerCC26XX_PERIPH_SSI1 5
#define PowerCC26XX_PERIPH_UART0 6
#define PowerCC26XX_PERIPH_I2C0 7
#define PowerCC26XX_PERIPH_TRNG 8
#define PowerCC26XX_PERIPH_GPIO 9
#define PowerCC26XX_PERIPH_UDMA 10
#define PowerCC26XX_PERIPH_CRYPTO 11
#define PowerCC26XX_PERIPH_I2S 12
#define PowerCC26XX_PERIPH_RFCORE 13
#define PowerCC26XX_XOSC_HF 14
#define PowerCC26XX_DOMAIN_PERIPH 15
#define PowerCC26XX_DOMAIN_SERIAL 16
#define PowerCC26XX_DOMAIN_RFCORE 17
#define PowerCC26XX_DOMAIN_SYSBUS 18
#define PowerCC26XX_NUMRESOURCES 19

I had include :
#include <ti/drivers/power/PowerCC26XX.h>
just like you said.

my purpose is easy , just want let CC2640 into sleep node , so I can test power consume will be 1~2 μA ,
but most of people tell me that I don't need to worry about how to into sleep mode or standby mode , TI RTOS
will into standby mode if nothing to do. I did , after awhile , power consume is 4.15mA . I am curious of how is it into standby mode
and power consume is 1~2 μA ?

If you use TI BLE stack and define POWER_SAVING, CC2640 would enter sleep mode when there is nothing to handle in task queue. If you use TI RTOS directly, I think this would be automatic.

You mean define POWER_SAVING ? Even I am not use BLE protocel , I still use TI BLE stack let CC2640 can working?
in SimpleBLEPeripheral project main.c code ,

#include <ti/sysbios/family/arm/cc26xx/Power.h>
...
...
...
int main(){
...
...
#ifndef POWER_SAVING
/* Set constraints for Standby, powerdown and idle mode */
Power_setConstraint(Power_SB_DISALLOW);
Power_setConstraint(Power_IDLE_PD_DISALLOW);
#endif // POWER_SAVING

it's gray area , means power saving is not working ?
}

That's why you said CC2640 will into standby mode if it's noting to do.
because I don't need to worry about power consume , it's automatic.
but when I measure cc2640 standby mode power consume , it's not low power ?
I mark SimpleBLEPeripheral_createTask() in main.c like this :
//SimpleBLEPeripheral_createTask();

Hello:
I still not fix Power_setDependency question.

If you use SimpleBLEPeripheral example, you don't have to call Power_setDependency.

In fact , I am not use SimpleBLEPeripheral example , I use Empty example:

Dear Tom:
I just want to verify CC26xx SimpleLink Wireless MCUs User’s Guide Chapter 3 , Example : UART Driver
