Hi,
I am working on an application which sometimes needs to send a buffer of a couple of KB to a connected smartphone using the nordic uart service.
The function used is ble_nus_string_send() and it can send a maximum amount of 20 characters at a time.
Is there a way to exactly know when the 20 characters finished sending so I can call the function with the next 20 chars, either via busy waiting or a callback? Currently I used a fixed delay and it is not optimal.
Many thanks, Josef
