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

 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

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

[awneil]

Sorry, I hit the 'report as abusive' button by mistake - I can't see anywhere to 'cancel report'?

See Simonr's post about checking your DK.

Does the COM port show up in the Windows device manager? Clearly, if it's not there then no app is going to be able to connect to it!

EDIT

Just to be clear, you mean this:

https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52-DK

Also, is it new & fresh out of the box - or has it been "previously enjoyed" by you and/or others for other projects?

Actually, I am working on a project which is opened using nrfConnect SDK v 1.4.0 and through this, it is connecting.

After disconnecting from nrfConnect

but when I am opening from C:\nrf_sdk\nRF5SDK16\examples\ble_peripheral\nrf5-calendar-example-master\pca10040\blank\ses

program is compiling but its not connecting to COM Port

[awneil]

The COM port is created by the interface chip - so it has nothing to do with what apps you're using on the PC, or what firmware is loaded into the Target chip.

You need to confirm that the COM port is visible in the Windows device manager - if it's not there, then clearly nothing can connect to it.

Please describe exactly the steps you are taking here, and what you are seeing - including any error messages.

Do you have any colleagues / teachers / etc locally who can help you?
