i try to connect and read and write on my device with ionic2 BLE plugin , i can connect and also write on the device but when i try to read a data from device and use startNotification i get error that say can't start Notification this is my code :
ble.connect(navParams.get("device")["id"]).subscribe((p) => {
this.d = "Success";
this.connected = "connected"
zone.run(() => {
this.status = "Connected"
})
this.data = JSON.stringify(p);
let lastChar = p.characteristics[p.characteristics.length - 1];
let serviceId = lastChar.service;
let chUUID = lastChar.characteristic;
let lastChar2 = p.characteristics[p.characteristics.length - 2];
let serviceId2 = lastChar2.service;
let chUUID2 = lastChar2.characteristic;
this.ble.write(navParams.get("device")["id"], serviceId, chUUID, this.stringToBytes("HOPE AGAIN")).then(() => {
// zone.run(()=>{
// this.status="Writing"
// })
})
this.ble.startNotification(navParams.get("device")["id"], serviceId, chUUID).subscribe(m => {
zone.run(() => {
this.status = "Notification"
})
// this.cdata = typeof p;
this.ble.read(navParams.get("device")["id"], serviceId2, chUUID2).then(s => {
zone.run(() => {
this.status = "Read"
})
})
},f=>{
zone.run(()=>{this.status=f})
})
//this.data = JSON.stringify(p);
})
and this is the home page of ble plugin and this is startNotification but i get error that cant start notifictaion on device with service id
