NRF52 adding CTS service( not CTS_C ) to application

[man]

I am using nrf52 DK board with  SDK15.3.0 developing my application on top of ble_blinky_peripheral example .

How do add CTS service in my application ??

 I have refered CTS_C ( client ) example which is provided with the SDK but , I want it to be configured for server since the CTS_C example needs to get paired first with the mobile app ( nrf_connect) and then it transfers CTS data . I want something like the CTS service (1805 ) should be available once I connect to the nrf device via nrf_connect app , and it must have necessary characteristics for writing CTS data .

Hi

The most common implementation is to use the nRF as the CTS client, and a phone or computer as the server, as the server will have to get the current time from somewhere (often GPS, WI-Fi or phone network).

If you'd like to use the nRF52 as the server, I assume you have some external time keeping device that you can read from, as the CTS is not meant to be used for setting time, but rather for a Client to get the current time from a server without user interaction. 

Best regards,

Simonr ,

thanks for the reply !

My application has calendar example using RTC  to have my date and time running and getting displayed on LCD display .    So I need to set all these timing parameters from the mobile app via CTS service . Then how can I use standard CTS service to send Date and Time from my mobile app without setting my nrf as client ?.

Even if the NRF is in client , and if the service is visible ( 1805 and  char UUID : 2A2B) without getting it paired , that should be enough for me since my application ( andriod / ios ) will take care of reading timings from  mobile device and sending it to the characteristics ( 2A2B ) .
