Nativescript bluetooth read continous data - nativescript

Question

We are using a EEG device which gives raw data every second. While using nativescript-bluetooth we are able to scan and connect the device but read returns only one value. What we want is continuous data reading and storing it.
I tried to read by bluetooth.read where the result is printed once but I want it to be called everysecond.
```
bluetooth.connect({
UUID: uuid,
onConnected: (peripheral) => {
peripheral.services.forEach((service) => {
console.log("service found: " + JSON.stringify(service));
this.deviceServiceData = service;
});
setTimeout(() => {
this.readDataFromDevice(this.deviceServiceData, uuid);
this.notify(this.deviceServiceData, uuid);
}, 1000);
},
onDisconnected: function (peripheral) {
console.log("Periperhal disconnected with UUID: " + peripheral.UUID);
}
});
}
notify(service, uuid) {
bluetooth.startNotifying({
peripheralUUID: uuid,
serviceUUID: service.UUID,
characteristicUUID: service.characteristics[0].UUID,
onNotify: function (result) {
console.log("read: " + JSON.stringify(result));
}
}).then(function () {
console.log("subscribed for notifications");
}, function (err) {
console.log("notify error error: " + err);
});
}
readDataFromDevice(service, uuid) {
bluetooth.read({
peripheralUUID: uuid,
serviceUUID: service.UUID,
characteristicUUID: service.characteristics[0].UUID,
}).then((result) => {
var data = new Uint8Array(result.value);
console.log(data);
}, function (err) {
console.log("read error: " + err);
});
}
How should I get the values generated by the device every second? Do I call `readDataFromDevice` at every time interval?
