Please look at the examples that include app_timer, I believe there is at least one in the /peripheral/ folder.

I understand your explanation :) and it's very helpful for understanding the goal but do you have an example that could be useful fr the app timer timeout handler thank you :)

Hello Kenneth thank you so much for your helo, do you have an example that I can use or see to see the use of data array in extern of the main and the use of APP TIMER DEF? thank you for your time

I guess there are many ways this can be solved.

You can make the UART data available globally in main.c by declaring data_array[] it on top of main.c (instead of in uart_event_handle()).

You can now use the uart_event_handle() to fill up the data_array[], but don't send data using ble_nus_data_send() from uart_event_handle().

You can for instance create an app_timer using APP_TIMER_DEF() that you start in main(), this app_timer can for instance be timeout every 1ms.

In the app_timer timeout handler you can call ble_nus_data_send() to send any received data in data_array[].

Something like that,
Kenneth

I saw that the function "app_uart_flush" could be used but I would like to have more explanations of how to put the function if this is the right thing to use. Thank you
