CC2650STK: cc2650STK and accelerometer lifetime caliculation.

Part Number: CC2650STK
Other Parts Discussed in Thread: CC2650, BT-POWER-CALC

Hi All,

I want to develop small application in which cc2650stk will get interrupted every 500 ms and send accelerometer data.

I have few doubts. I am new to cc2650 so please excuse for silly doubts.

1. I commented all the code related to other sensors. Is it enough or i have to do any extra precautions to reduce power.

2.How to measure power in micro amperes with cc2650stk?

3.I am able to read accelerometer data but accelerometer interrupt is not triggering to wake up the cc2650. what might be the reason?

4.Is the cc2650stk code optimised for power or i have to make the cc2650stk to sleep after transmitting the ble packet?

5. Is any one tried mesuring the life cycle for cc2650stk and accelerometer which transmit the ble packet at every 500ms?

Thanks,

Devika.

    1. Yes.

    2. You can refer to for CC2650STK power consumption measurement.

    3. I suggest you to use scope to check if interrupt pin is triggered first.

    4. I think you still can do fine tuning to application code to optimize power consumption according to your own use cases.

    5. You can try to use BT-POWER-CALC to estimate power consumption.
