So far our verification has not shown like this report.

• Device information which this issue occurs (Model name, OS)
• Printer (Model name, Firmware version, Communication Interface)
• Development environment
  • The result of executing the command ver on Windows, sw_vers on macOS, uname –a on Linux, or these equivalent commands, and the result of executing the command npx react-native info.
• Reproduce procedure or your source code

Thank you in advance.

This has happened to us a couple times. If we restart the device, forget the bluetooth connection and reconnect then the error goes away.

Device information in which this issue occurs -

Device name - iPhone 14
OS - iOS 17

Printer -

Model name - TSP143IIIBI
Interface Type - Bluetooth
Firmware version - 3

The issue is on iOS, the connectivity works perfectly but when I try to open the printer, it gives me the error StarIO10CommunicationError: Open failed. But the same functionality works on Android.

FYR - I've also tried the soution given by @zacdemi, didn't work for me.
