Using ACK payloads is the definitely easiest way, so I'd recommend you to go with this.

Thanks for your reply,

For our application, is to make a remote which could have bi-direction audio communication.After compression, its size could be under 300kbps.

For now, the problem is how to realize it via gazell. It mean how to get the data from dongle(host) to device. For my guessing , there are 2 ways to do it.

(1)Put the data in ack packet,so that host side could send the data. (2)Switch RF mode, remoter could be host&device,so did by dongle. (3)Your suggestion

For this kind of application. Distributor can't support us. So i'm really appreciate for your help.

If you can do with relatively low data rate (300-400 kbps), Gazell should be fine. You can do bidirectional data transfer out-of-the box, so no modifications should be needed.

If you want to write an RF protocol from scratch, you may have use in taking a look at this.
