Send data to Client.

[Elliot.Chao]

Hi,

If I want to send data(400Bytes) to client(phone),I must use sd_ble_gatts_hvx to notify client. Is it right? Every time I notify 20bytes until the end, is it right?

There is other way to do it? Or Can I send 400bytes at one time? Do you have any example code?

Thank you.

Yes, you must notify 20 bytes at a time, and handle the data splitting in your application.

We don't really have any exact examples of this, but you may have use in looking at this branch of the nrf51-ble-app-lbs GitHub repository. It shows how you can do a throughput test for a given Central, and hence how you can send multiple 20 bytes notifications as fast as possible.
