FlutterBluePlus Version

^1.15.1

Flutter Version

3.10.5

What OS?

Android

OS Version

10

Bluetooth Module

Nordic

What happened?

I tried with a timeout of 15 and 30 but was not able to discover the services...Sometimes it does discover services in a defined time. I connect the BLE directly via the Device address. Here is BLE device: {remoteId: device address, localName: dice, type: BluetoothDeviceType.le, isDiscoveringServices: false, services: null}

Even if i disconnect the device and connect again..It couldnt discover services.

update to 1.15.8 & post all logs, not just the error

amirsuwal01 commented 10 months ago

The issue is resolved once the ble is disconnected properly.

@amirsuwal01 What do you mean by disconnect properly?

chipweinberger commented 8 months ago

he is referring to a bug in FBP that has been fixed

FBP was not updating its internal state, so it thought it was still connected but it wasn't

@chipweinberger Possible this is still happening? I was running perfectly fine with my BLE arduino code, then out of nowhere started getting these errors:
