RTOS/CC2640: How to configure access to low power consumption

user4937874

Part Number: CC2640

Tool/software: TI-RTOS

Hi:

Ti engineer!

I use the example of C:\ti\simplelink\ble_sdk_2_02_01_18\examples\cc2650lp\simple_peripheral example, modify the chip to be packaged as 4XS, and the power consumption of the broadcast is 1.4 mA, and how I should be able to achieve uA. POWER SAVING has been defined, and display is closed.

Thanks!

Hi,

Please see the app note Measuring Bluetooth Low Energy Power Consumption ( http://www.ti.com/lit/swra478 )

Hi，
My PCB with an external flash and a sensor, but now I don't use these sensors, I choose the piece of these sensors signal processing is closed, power consumption in 300 uA, this kind of situation is normal, please?

Hi,

What kind of sensors do you have?

If you are using a custom board, did you check the hardware checklist ( processors.wiki.ti.com/.../CC26xx_HW_Checklist) and the HW troubleshooting guides (processors.wiki.ti.com/.../CC26xx_HW_Troubleshooting)

Hi，

Now encountered a situation is this: 50pcs module will be found about 15% of the module not broadcast about a day,and reset the module will be normal. I'm use simple_peripheral , internal RC.There are very few module to test VDDR is 0, the other is 1.67 V, what is this excuse me?

Hi,

Did you see the "Known Issues / Workarounds for BLEv2.2.1", processors.wiki.ti.com/.../CC2640_Porting_Projects . There is an issue where the device stops advertising after a while. Does this describe what you're seeing? (See also the work-around.)
