How to measure two wave delay?

[B]

I have two square waveforms coming out of a pin each. I want to measure the delay between them. Which command should I use? How can I do this?

[B]

In the microcontroller registers. it's possible? Because I want to send these measurements by Bluetooth to a mobile How can I do this?

You can store the measured delay any way you want, in variables, write it to flash, or send it over BLE using Nordic UART service or custom BLE service.

Thanks a lot! I'm using this microcontroller a little time so I have difficulties.

Hi Jorgen, How do I send those values ​​that are leaving the terminal to a mobile application using the app inventor, or android studio?! I do not know how to do this. How would the microcontroller code? Could you help me by sending an example please?!

You send it the way described in the links I posted above. I do not know how you receive the values in app inventor or android studio, as I have never used either of those. You should ask that question on the support portals for those development tools.
