How to connect iOS app to a hardware and communicate via WiFi?

I am not sure how the mentioned app has developed their technology, but if you wanted to communicate with a device for networking or data feed purposes you could connect to an adhoc Wi-Fi network the device is broadcasting with the NEHotspotConfiguration and NEHotspotConfigurationManager APIs. The NEHotspotConfiguration API would create the Wi-Fi network configuration and then NEHotspotConfigurationManager would actually apply it to you device to associate to the adhoc Wi-Fi network.

Thanks a lot Matt! I will give it a shot

Hi Matt! I did follow your approach and I've successfully establish the connection by using both NEHotspotConfiguration and NEHotspotConfigurationManager. However, how can I actually read/retrieve the data that's being broadcasted from the device (e.g. BeBird's endoscope) and present it in the iOS APP?

Excellent. Glad that worked for you.

Reading the data from the device would be dependent on how the device provides the data. If there is a connection listener that you need to create a TCP/UDP connection to, you would need the IP of the device and the listening port and you could attempt to create a connection through the listener. Discovering a Bonjour service is also another great way to not have to look for an IP, but instead, perform service discovery and then connect to your listener through a service endpoint.
