CC2650STK: Help Wanted to Limit Sensor Capabilities, Extend Battery Life

Joe Ackert

Part Number: CC2650STK

Hello - 

I am using a CC2650STK for prototyping purposes and request help in creating the firmware changes as follows:

  • Functional
    • Only need IR Temp, Humidity, Luxometer, Accelerometer and Battery capabilities.
    • All else can be disabled
  • Extended Battery
    • From what I've read putting the sensors in low consumption mode helps?
    • Other suggestions on extending battery life.

The default firmware currently lasts about 36 hours given my integration (with nodejs). From what I've read on forums, this can be extended by customizing the firmware on the CC2650STK however, it requires a Windows machine as well as a grasp of C programming etc. - items that I'm not interested in spending time on if at all possible.

Looking for help - thanks in advance!

Joe

    Hi Joe,

    I'm afraid we can't supply you with a done and ready firmware for what you look after, you will have to modify the firmware yourself to fit your requirements. A good start for this is the examples that is available for CC2650STK as you should be able to take the source of what you are running now and make the necessary changes.

    Disabling the sensor you don't need a good start to lower the power consumption.

    M-W - thank you for the response. Could you elaborate on what this means:

    "Disabling the sensor you don't need a good start to lower the power consumption."

    Thanks

    Hi Joe,

    It would depend on the sensor in question but generally you could assume that you could do this over I2C as most sensors are connected using this interface.

    Again exactly how depend on the sensor but if there is power-saving modes available you should be able to enable it by sending the correct command for that sensor. For example does page 15 in the BMP280 datasheet touch how you move between the different power-modes that is available.
