Hi,

I have an app which needs to connect with a external device via wifi (External device is working as Access point).

Once connected to device it besically streaming data and notify events using GRPC.

Now i need to support background mode so that iPhone should able to listen all the events in background also.

Thanks

For connecting to your accessory I would look at using the NetworkExtension API NEHotspotConfiguration. Once you are connected you can use a NWConnection to run RPC over TCP or UDP. In regards to performing this functionality in the background, my first recommendation would be to investigate using BGTaskScheduler to see if this meets your background needs.
