Hi,
I have some kind of similar issue in the sense that my application works fine on android and not on iOs.
Do you have any idea why : #1184
from react-native-ble-manager.

I'm guessing it's not related to this issue, this issue happens on transmission between characteristics
from react-native-ble-manager.
Ok thanks
from react-native-ble-manager.
For anyone that could have this issue it can be solved on react-native app level.
In order to support many known short characteristics/services uuids we can do as following:
function onCharacteristicChange({
value,
peripheral,
characteristic,
service,
}) {
if (peripheral === id) {
let isSameCharacteristic = false;
let isSameService = false;
// Characteristic
if (characteristic.length === 4) {
isSameCharacteristic =
characteristic.toLowerCase() === shortCharacteristicId;
} else {
isSameCharacteristic =
characteristic.toLowerCase() === characteristicId;
}
// Service
if (service.length === 4) {
isSameService = service.toLowerCase() === shortServiceId;
} else {
isSameService = service.toLowerCase() === serviceId;
}
if (isSameService && isSameCharacteristic) {
console.log('it works');
}
}
}
let listener = BleManagerEmitter.addListener(
"BleManagerDidUpdateValueForCharacteristic",
onCharacteristicChange
);
`
