Notifications don't stop when the disconnection is triggered by the device side

Describe the bug
Notifications don't stop when the disconnection is triggered by the device side. Future BleClient.startNotifications won't work for future reconnections in that situation. Using BleClient.stopNotifications inside onDisconnect doesn't help as the device is already disconnected at that point.

To Reproduce
Steps to reproduce the behavior:

  • connect to a device
  • call BleClient.startNotifications
  • power cycle the device
  • try to connect again
BleClient.connect(device.deviceId, async (disconnectDeviceId: string) => {
  try {
    await BleClient.stopNotifications(
      disconnectDeviceId,
      CONSTANTS.UUID16_SVC_BATTERY,
      CONSTANTS.UUID16_SVC_BATTERY_CHAR_BATTERY_LEVEL,
    );
    await BleClient.stopNotifications(
      disconnectDeviceId,
      CONSTANTS.UUID128_SVC_NORDIC_UART,
      CONSTANTS.UUID128_SVC_NORDIC_UART_CHAR_TXD,
    );
  } catch (error: any) {
    console.warn(`onDisconnect: ${error.message}`);
  }
}),

Expected behavior
Notification should stop when the disconnection is triggered by the device side

I cannot reproduce this. On which platform is this happening (iOS or Android)? Can you share the native logs?

It looks like this issue didn't get the information it needed, so I'll close it for now. If I made a mistake, sorry! I am just a bot.

Have a great day!
