getDiscoverServices throws fatal exception

[rsubramanyam2994]

Describe the bug
We are seeing a variety of fatal exceptions like: java:1311)] reactive_ble_mobile_platform.dart in ReactiveBleMobilePlatform.getDiscoverServices.<fn>, where the line of java code keeps varying like java:1457)], etc and the exception remains the same.

To Reproduce
Steps to reproduce the behavior:

1. We connect to a single device using connectTo()
2. We read and write to a single non-protected characteristic
3. We aren't able to consistently replicate this but this keeps happening now and then. Sorry about that.

Stack trace:

Expected behavior
We don't understand why this happens. Based on ble logs, we do observe that, even after disconnecting, the getDiscoverServices continues to happen.

Smartphone / tablet

• Only Android devices (Android 11, Android 12, Android 13)

Peripheral device

• https://www.movesense.com/movesense-active/ with a custom firmware

Additional context
I understand the above information may not suffice. Please let us what kind of things to try/replicate so that we can give you further info to debug this.

The library does not invoke getDiscoverServices by itself, so it is not clear what you mean by getDiscoverServices continues to happen even after disconnecting. Are you sure this is not being triggered by your code?
