Method to use for streaming data to device

[askdesigners]

I'm looking to stream small packets of data across to an esp32 in realish time. Using the write method for a characteristic works but is very slow. I'm looking to sent data every 10 or 15ms and it just can't keep up. I've read that using a notification or a broadcast can work better but I have not managed to make this work with Noble. Is there a way to attach data to a notification?
