How to get UTC into ble_date_time

[RPDben]

Hi,

I am trying to get date and time on my nrf51822 but struggling a bit. I would like the nrf to receive the time over BLE and then increment it internally using the RTC. When the nrf next connects to another device it should automatically update the time again in case of power off, etc.

I would also like to be able to get the time in ble_date_time format so I can pull out months, days, hours, minutes, etc.

I am using an nrf51822 with the s110 softdevice.

If anyone could point me in the right direction I would be very grateful.

Did you look at the current time service in our sdk: nRF51_SDK_9.0.0_2e23562\examples\ble_peripheral\ble_app_cts_c

Thanks for this, I am looking through the example now. Two things I cannot work out:

1. What function do I call to get the time

2. How do I append this to the RTC?

Thanks,

1. The current time is read using ble_cts_c_current_time_read(). this function is called from the bsp_event_handler.
2. Use the current time to sync your local time. This means that you should also have a local time that you update based on the RTC. To see how to use the RTC you can look at nRF51_SDK_10.0.0_dc26b5e\examples\peripheral\rtc\

I have looked at that and understand how the RTC module is working. However, and forgive me if I am being rather ignorant here, I cannot see how you set say RTC2 to know the current time.

My application basically needs to store the current time & date when an event has finished. The soft device uses RTC0, my application timers use RTC1 so I would like RTC2 to keep track of the time and then store it (using pstorage) when requested. Apologies again if I am missing some blindingly obvious point.

As you can see in case BLE_CTS_C_EVT_CURRENT_TIME (main.c line:303). We only print the current time once received. In your case you have to store this value. I would suggest using current_time_char_t. Then you use the rtc timer to update this value.
