UndeliverableException thrown / OnCompletedFailedException - Help needed

[cogesmobilesolutions]

Describe the bug
We been receiving so many crash for UndeliverableException.

We are recreating the client everytime when connect the device using the code snippet below.

rxBleClient = RxBleClient.create(this.context)

But the documentation suggest, It's your job to maintain single instance of the client so, by moving the client initialation
to the application class will help to reduce the problem?

Also i attach a stack trace as well.

TBH I have not seen this problem yet. Keeping a single client could help as all required thread pools won't get deallocated.

Try keeping a single client for the whole application lifecycle and report back what you will experience.

@dariuszseweryn Thank you for your reply, we will keep single client and let you know the feedback.
