Summary by Entelligence.AI

- Bug Fix: Improved the stability of device connections in the `DeviceProvider` class. This fix introduces a slight delay before attempting to reconnect upon disconnection, preventing potential race conditions.
- Refactor: Simplified connection logic in the `DeviceService` class by removing unnecessary checks for connected devices before ensuring a connection. This change enhances the efficiency and reliability of device connections.

Walkthrough

The changes introduced aim to enhance the stability of device connections in the application. By introducing a delay before reconnection attempts and removing unnecessary connection checks, we've mitigated potential race conditions and streamlined the connection process.

Changes

File(s)	Summary
app/lib/providers/device_provider.dart, app/lib/services/devices.dart	Introduced a 1-second delay before calling periodicConnect in the onDisconnect method to prevent race conditions. Removed the check for connected devices before ensuring connection in the DeviceService class, simplifying the connection process.

🎉 With every line of code, we strive,

To make our app more alive.

No more races, no more checks,

Just smooth connections, tech perfects. 🚀

The removal of the check for a different connected device could lead to unexpected behavior. If a connection attempt is made with a different device ID while another device is already connected, the new connection will be attempted without disconnecting the previous one. This could potentially lead to multiple devices being connected at the same time, which might not be the intended behavior.

To fix this, you should reintroduce the check and throw an exception if a different device is already connected. Here's how you can do it:

+      if (_connection != null && _connection?.device.id != deviceId) {
+        throw Exception("There is a connected device ${_connection?.device.id}, you have to disconnect it first.");
+      }
       debugPrint("ensureConnection ${_connection?.device.id} ${_connection?.status}");
       if (_connection?.status == DeviceConnectionState.connected) {
         var pongAt = _connection?.pongAt;
         var shouldPing = (pongAt == null || pongAt.isBefore(DateTime.now().subtract(const Duration(seconds: 5))));

This way, we ensure that only one device is connected at any given time, maintaining the integrity of the connection process.
