Tool/software: Code Composer Studio

Hello All,

We are using CC2640 eval board currently for testing, planning to use same chip CC2640R2FRGZ to our coustom board design.

For software development using the reference code from "simplelink_cc2640r2_sdk_1_50_00_58",  "simple_peripheral_cc2640r2lp_app".

My application will be device to mobile app communication, I have added my application code to this now it is working, i have the below queries. Please guide me on the below:

1). I need to do the power optimizatoion, i have followed the swra478c document in the section 4.2. I'm able to do 2nd & 3rd point only since we are using periodic event in the application not able to do the 1st one. Do i need to do anything else for power optimization.

2). I have increased the advertizing interval to 1sec and DEFAULT_DESIRED_CONN_TIMEOUT to 1sec . Do i need to do anything else for power optimization.

3). To increase the range between device and mobile communication i have done only DEFAULT_TX_POWER to 12. From this i can see vey less range around 25-30 feet. Please guide me how can i increase the range.

Thanks.

    1. You should do power measurement to see if it matches swra478c and your expectation. If not, you go to check why it doesn't match.
    2. Doing adverting a while and if there is no connection, stop advertising for a while and do advertising again later to save power.
    3. If you increase TX power, it would consume more power. Is that what you want?
