Starting, reading from and starting RTC clock from Android using nRF Connect or Thingy52 app

[tobiass]

Hello,

is there any tutorial on how to send commands to the Thingy52 from an Android app (like the Thingy52 app or nRF Connect) to start the RTC clock (and then read/clear the registers and so on)? Or do you need to write your own Android app/change the Thingy52 firmware for this purpose?

Best regards,

Hi Tobias,

The Thingy:52 firmware uses app_timer instead of RTC, so you will need to modify the firmware in order to change this.

If you want to be able to star/stopt the RTC clock using BLE you will need to create a custom service/characteristic for your Thingy:52, update the firmware and then use nRF Connect to write to the characteristics. Then start/stop RTC in the write handler of the characteristic.

I would recommend going through our Getting started tutorials on Devzone (Services/Characteristics) and start the development using a nRF52832 DK, then update the Thingy:52 FW to include your custom service and characteristic.

Best regards,

Marjeris
