Just to clarify, in BLE, you send data over Services and Characteristics. We have tutorials that you can have a look at here.

The example mentioned uses the Service "Nordic UART Service" and the two Characteristics "TX" and "RX" to transfer data.

Take a look at the function uart_event_handle() to see how it transfers data via the Nordic UART Service. The data received over UART is stored in data_array and sent using ble_nus_string_send(). In your case, inside ble_nus_string_send() you will find the function sd_ble_gatts_hvx(). You can use this to send data. Have a look at this post.

Hi,

What do you mean by displaying a message on your phone? If you just want to send a message from the device and receive it on your phone(in the app), then I suggest you have a look at the UART example in our SDK.
