Example for getting and setting rtc time using app using nrf52832

[Rajbir Singh]

Hello,

I have just started learning nrf. I have an nrf52832 board and I want to get and set time using app.

I have seen this https://devzone.nordicsemi.com/f/nordic-q-a/57827/nrf5-calendar-example-questions

but haven't got much.

Please suggest me some examples.

Thank you in advance

Hi, thank you for your reply. 

I am new with nrf. Actually, I have done only Arduino Programming only.

I am familiar with C programming, but the problem is I haven't done any microcontroller programming yet that's why I am getting confused.

Because in nrf there are many directories and all the interlinked.

I am using nrf52832 DK 

basically, I want to set and get time from the android app to nrf52832 DK.

Could you please help me, how to get and set time using app

 To compile it, clone the repository in the [SDK]/examples/peripheral/ folder in SDK v16.0.0.

I just did the same as you said but got the error

So, again, you need to go through those Getting Started links - they introduce you to the chip, and the SDK, and the development process.

As with learning any new skill, it's important to start with the basics, build solid foundations, and work up a step at a time - rather than just leap in at the deep-end where you're out of your depth.

I think that should be:  [SDK]\examples\ble_peripheral

Which then gives me an SES Project "nrf_calendar_pca10040.emProject" in:

[SDK]\examples\ble_peripheral\nrf5-calendar-example-master\pca10040\blank\ses

If I open that, and do Build > Rebuild within SES - it builds successfully.

Thank you, after rebuilding its compiled, now where I can see the time because serial port is not connecting and aslo in the nrfConnect app its not showing up
