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.

So far, no such report has emerged from our verification. However, we would like to confirm this. Can you provide specifics on how to reproduce this?

[shriganesh64]

Post connection establishment with the printer I tried to use the printer.open(), This fails with the above error on iOS but works with Android. I'm using the latest star print package with version 1.7.0.

Thank you for sharing the information. Please let us know the below:

1. Can you build an app?
2. Are you using the CLI? or Expo (EAS)?

[shriganesh64]

I'm able to build the app, Shared the react-native info here.
We're using the CLI for our app, Tested the integration on a temp project facing the same issue there as well.
