When using a mesh network and the Lithe Audio iOS app doesn't show devices on the network, several factors could be causing the issue:

1. Network Segmentation:

   • Mesh Network Configuration: Some mesh systems create separate network segments for different bands (e.g., 2.4 GHz and 5 GHz). If devices are connected to different segments, the iOS app might not be able to see them, depending on how the mesh network is set up.
   • VLAN or Subnet Configuration: If the mesh network is configured with different subnets or VLANs for various devices, the iOS app might not have visibility across those subnets. This can happen in more complex setups where the devices are isolated from each other.

2. Device Discovery Protocol:

   • mDNS/Bonjour: Many apps (especially those by Apple) rely on mDNS (multicast DNS) or Bonjour for device discovery on the local network. If mDNS is blocked, misconfigured, or disabled on the mesh network, devices may not show up on the iOS app.
   • SSDP Issues: If the mesh network relies on Simple Service Discovery Protocol (SSDP) for discovering devices, network issues like misconfigured firewalls or network isolation between devices can hinder visibility.

3. App Permissions:

   • Local Network Privacy Settings: iOS 14 and later have a privacy feature that requires apps to request permission to access local network devices. If this permission is not granted, the app won't be able to see devices on the network.
   • App Configuration: The app itself may need to be configured correctly to discover devices. Ensure the app is up-to-date and configured to detect devices on the local network.

4. Wi-Fi Bandwidth & Connection Issues:

   • Roaming Between Nodes: If devices are roaming between different mesh nodes, their connection might temporarily drop or be weak, causing the iOS app to not detect them.
   • Low Signal Strength: Devices might not show up in the app if they are too far from the mesh node or if the signal is weak, leading to network instability.

5. Network Isolation:

   • Client Isolation: Some mesh networks, especially guest networks or networks with security configurations, isolate devices from one another. This means that even though devices are on the same mesh network, they may not be able to communicate with each other directly.
   • Bridge Mode vs. Router Mode: Some mesh systems may have a "bridge mode" or "router mode." Devices in bridge mode might not be properly detected by the iOS app if they are on a different network layer.

6. Firmware or Software Issues:

   • Mesh Node Firmware: If one or more mesh nodes have outdated firmware, they might be causing compatibility issues, preventing the devices from appearing in the iOS app.
   • App/OS Compatibility: Ensure the mesh network app is compatible with the version of iOS you're using. Incompatibility might prevent it from showing devices correctly.

Troubleshooting Steps:

• Ensure local network access is enabled for the app in your iOS settings.
• Verify that all mesh nodes are functioning correctly and that devices are connected to the network.
• Check for firmware updates for both the mesh network and the iOS app.
• If possible, reset the network settings on the iOS device to clear any potential misconfigurations.
• Check the mesh network's SSID and security settings to ensure devices are on the same network.
• Restart the mesh network to refresh connections and ensure all devices are properly connected.
