cc2640 module power optimization

Other Parts Discussed in Thread: CC2640

Vijay here. our team is designing the smart lock that is power by AA Alkaline primary cells and cc2640 is used as the central part of communication and control.

The problem we are facing is about high power consumption and we not able to find where we are making mistake , maybe it is with the wrong circuit design or with ble module or may be not the right firmware, hence we need help from TI so that we can innovate our product with TI solutions.

Here I listed the external circuit that has five in series cells which power both the step motor used to move the lock mechanical part and ble module. along with that, three reed switches are also used for state information. The end terminal of five series connection is used to power motor and voltage is about 7.5 volt and two series inbetween cells are used to power the ble module. for help, files are attached . so could you tells us where we are making mistake.Schematics (1).pdf

Thanks

Hi Vijay,

What version of the TI BLE SDK are you using? Are you using an example project from the SDK to do your power measurements? The TI BLE Software Developer's Guide has information about decreasing your power consumption: http://www.ti.com/lit/pdf/swru393

There are lots of factors that could increase your power consumption. Please see the following app note for help with your system design: http://www.ti.com/lit/pdf/swra478

Hi RachelP,

we are using ble stack 2.1.1 and CCS to build the application.

I will go through the guide you suggest. The battery configuration (connecting ble module in between ) shown in previous message is good to go.

Thanks
