[kai-morich]

Looks like an Android internal issue, not an issue in this library. is it reproducible?

[si5haoa]

appear inevitably 。 I have used usbSerial. jar with the same device before and did not find this problem

[kai-morich]

have you tried rebooting your Android device?

[si5haoa]

The same thing happens after restarting the device Getting messages is getting slower and slower and then crashes

[kai-morich]

did the App already recieved a lot of data? This example app simple adds everything to the TextView, which gets significantly slower the more data is shown. Maybe you simply ran into timeout or out-of-memory issue.

Thank you, I will remove the relevant part of the UI and test it, and simply send and receive data to test

[si5haoa]

Thank you very much, I will delete the UI and receive the data, no problem
