I faced the same problem. Did u manage to workaround it? I run the iPhone 11 emulator.

[januslo]

Emulator would have build issue that the package cannot be installed. Plz try to use the real device to check whether problem still.

hi @januslo I just tried implementing the bluetooth ecpos printer in my repo. However, I face this issue as well. I run on real device(android) via expo, but still got this error. Is there some config I missed ya?

1. add the file RNBluetoothEscposPrinter.podspec and pod install
2. replace '#import "ZXingObjC/ZXingObjC.h"' by #import "ZXingObjC.h" in RNBluetoothEscposPrinter.m

Did anyone get a solution? I'm running on physical android device and I can't get out of this error.

[Kyiomi]

Same problem here. Running on physical android device.

[RaduMirceaAndrei]

This applies to iOS in expo bare enviornment.

Install the package from github, not via npm repository. npm install https://github.com/januslo/react-native-bluetooth-escpos-printer.git --save

In case you already installed via npm, go to your ios folder and do a: pod deintegrate Then go back to your root folder and install it via the github repo (above command)

As of writing this, iOS emulators do not support Bluetooth so you need a real device.

[anubhav-sri]

Still fails for me

[CorentinHeroux]

Same for me, 'BluetoothTscPrinter.DIRECTION = { FORWARD: 0, BACKWARD: 1 }'), Iphone 11 pro

[Bilel-Fitouri]

You should apply this update

https://sochinda.wordpress.com/2020/09/02/config-januslo-react-native-bluetooth-escpos-printer-in-react-native/

then pod install (that should install the RNBluetoothEscposPrinter dependency)
