I am using the gazell protocol of nrf52840,how to use broadcast radio mode from host to device based on the gazell protocol?or can I use the gazell protocol to make it possible to use broadcast radio?

Hi 

Gazell is not designed to do broadcasting. Every packet you send requires an ACK packet to be sent in return, and this doesn't really work for broadcasting purposes. 

If you want to do broadcasting I would suggest using the nrf_esb protocol instead. Then you can disable the ACK feature when needed, allowing you to send broadcast packets.

But I need host to send broadcast packets,and the device to be the receiver when this protocol works for broadcasting purposes.Is nrf_esb posssible to make it?

Hi 

You mean you need the same device to both send and receive broadcast packets?

This is possible with nrf_esb, but you need to change the mode from PTX to PRX or vice versa in order to do it (in PTX mode you can send packets, and in PRX you can receive them).
