Let me use this app without wifi

[arodier]

I am using this application as an alarm in one room, and the viewer is connected to my box's vpn. So, they're on the same network, even when I am away.

Please, remove the obligation to use the wifi. For those using a VPN on two phones, this is not needed either.

Unfortunately, this phones cannot find each other if one or both are using VPN. Here is the technical expination:

When a device connects to a VPN, its network traffic is routed through a virtual private network, effectively isolating it from the local network. This means the device is not directly visible on the same subnet as other devices connected to the local Wi-Fi. Network Service Discovery (NSD) relies on multicast DNS (mDNS) for device discovery, and mDNS typically operates within a local network (i.e., a specific IP subnet). Devices behind a VPN might not participate in this mDNS discovery.

Nope.

My router has VPN server included (wireguard), and I use it when I am abroad, to watch the BBC. The VPN runs on the network, and gives IP addresses in the same LAN as the main home network, and I can access my Synology from the phone.

In other terms, yes, it works, so let the users choose if they want to use wifi or not.

I'm not actively restraining using the VPN. As I explained before, the VPN devices cannot find the other wifi devices because they cannot be looked up via DNS. If they knew each other's IP address they can communicate.

This is an open source project, so feel free to submit a pull request if you think you can add this feature.

Please, just disable the WiFi enforcement, that's all I ask.

Removing a "feature" should be simple.

I have my own project to contribute.

Andre.

I can see the error message here: https://github.com/izivkov/RemoteVideoCam/blob/dd2a1cb043c8710dcbd140973b9c76e7b0c17754/app/src/main/java/org/avmedia/remotevideocam/MainActivity.kt#L49

The fact that both nodes cannot connect could be another issue than wifi. For instance, some boxes don't allow wifi clients to "see" each other.

I will test again with a wifi access point.
