Same issue

Hi guys, you need to set the devices on react state, then react will re-render and available devices will be into state

Having the same issue on iOS. Android works fine.

Have you correctly defined the UISupportedExternalAccessoryProtocols,NSBluetoothAlwaysUsageDescription & NSBluetoothPeripheralUsageDescription on IOS ?

lchenfox commented 1 month ago

@axelmarciano Hi, I have already added NSBluetoothAlwaysUsageDescription and NSBluetoothPeripheralUsageDescription without UISupportedExternalAccessoryProtocols. Would you please tell how to add UISupportedExternalAccessoryProtocols and set it's values? So far, getDeviceList still cannot get any reponse on iOS. Any help will be appreciated.

axelmarciano commented 1 month ago

UISupportedExternalAccessoryProtocols should contain manufacturer-specific values. For example:

Epson: com.epson.escpos
StarPrnt: jp.star-m.starpro These values allow the application to correctly communicate with the external accessories.

@axelmarciano Thank you so much. I'll have a try.
