Hi.....

i want to transfer the data for every one minute from peripheral device to phone  (nrf connect ).. how to declare in the program and what function to be used ?

suggest me a idea 

i am using segger (sdk 12.3 version) . debugging the program to peripheral through my development kit nrf52382

It sounds like you want some sort of timer in your application. You could draw some inspiration from the simple_timer example in the sdk.

simple_timer i gone through ... but i need to transfer the data for every minute , so every minute it should check the peripheral .. can u help me

Have you studied the Timer documentation?

The same way you'd write code in any other application.

Do you have any programming experience?

yes , but i have used arduino only .  i want to modify the heart rate(hts program) in that i want to include the timer. To read the data for every one minute . please help

As @awneil said, you will have to merge things from two different projects. I suggest you start with a BLE example, such as ble_app_hrs if you need to send heart rate data, or the ble_app_uart if you want to send custom data. Then look at the app_timer example, and try to add a timer from this example into the ble_app_uart example.

One fall pit that I think I should warn you about is that the app_timer example uses TIMER0, in most SDK versions. This timer is reserved for the softdevice, so switch to TIMER1.

Best of luck,

Edvin

If you take a look at this case, you will find an example attached, which is similar to what your goal is. Download the zipped file, unpack it to SDK15.0.0/examples/peripheral (This is the sdk it is tested with). It uses the Application Timer library, and turns advertising off and on for every 10 seconds.

If you are able to do this, you can advance to the next step (look at the function heart_rate_meas_timeout_handler() in the ble_app_hrs example for inspiration)
