iOS Crash sometimes

See original GitHub issue

Mobile Device Environment Provide a list of operating systems on which this issue is relevant.

Device: iPad
OS: iOS 15

Application Environment Provide information about your development environment:

React Native version: v0.64.1
RN Bluetooth Classic version: v1.60.0-rc.16

Describe the bug Sometimes after a while that I have connected the BT device, and I have sent and received data the app crashed. I think it could be a problem with memory because the device is always sending data and I see in logs that is constantly saying Stream %@ has bytes available. But this is my simple guess. The Bluetooth device is a LEGO Spike Prime.

The app crashed with this error and occurs in the DelimitedStringDeviceConnectionImpl.swift file line 237
