It didn't find the right characteristic. Make sure you got the right UUID

quick_blue/quick_blue_macos/macos/Classes/QuickBlueMacosPlugin.swift

Lines 25 to 33 in f451df7

public func getCharacteristic(_ characteristic: String, of service: String) -> CBCharacteristic {
let s = self.services?.first {
$0.uuid.uuidStr == service || "0000\($0.uuid.uuidStr)-\(GSS_SUFFIX)" == service
}
let c = s?.characteristics?.first {
$0.uuid.uuidStr == characteristic || "0000\($0.uuid.uuidStr)-\(GSS_SUFFIX)" == characteristic
}
return c!
}

Could you post the service discovery log?

Right e5f5f000 and e5f50001

await QuickBlue.writeValue(connectedDeviceId, "e5f50000-c0ec-46ba-bd1f-b4c9f0da4208", "e5f50001-c0ec-46ba-bd1f-b4c9f0da4208",
Uint8List.fromList(valuesKey + values), BleOutputProperty.withResponse);

Wrong e5f50000 and e5f50001

Still getting same error
void updateFriendlyName() async{
var valuesKey = utf8.encode("F") ;
var values = utf8.encode(friendlyNameTextController.value.text) ;

await  QuickBlue.writeValue(connectedDeviceId, "e5f5f000", "e5f50001",
    Uint8List.fromList(valuesKey + values), BleOutputProperty.withResponse);

}
