RE: BLE NUS sending notification

Hi,

[quote user=""]I am not sure what function triggers the notification or a good place in documentation to understand how to do so.[/quote]

It's the SoftDevice function sd_ble_gatts_hvx() that is used to send notifications. In the ble_app_uart example, the function ble_nus_data_send() is using the sd_ble_gatts_hvx() to send notification based on what it receives over UART.

If I understand you correctly, then you can send a notification, and when you receive the notification on the central side, you send the next write command from the central.
