noble_base

Typescript compatible Noble base class for manipulating BLE peripheral devices

Install

npm install noble_base

Usage

Take a look at the src/examples. Basic pattern is as follows:

1. Extend NobleBase.Base class

   class ExamplePeripheral extends NobleBase.Base {
     public is(peripheral: Noble.Peripheral): boolean {
         //return true if you want connect to this peripheral
     }
   
     protected async onConnectAndSetupDone() {
         //do something when peripheral is connected
     }
   }

2. Implement is() and onConnectAndSetupDone() methods
3. In your application code instantiate ScanHelper for your child class

   let scanHelper = new NobleBase.ScanHelper<ExamplePeripheral>(ExamplePeripheral);

4. (optional) Apply scan filter

   scanHelper.setScanFilter((peripheral) => {
       //return true if peripheral should be connected
   });

5. (optional) Attach device discovered callback

       //called each time new SimplePeripheral is connected
       const deviceDiscoveredCallback = (peripheral: ExamplePeripheral) => {
           //do something with peripheral
       }
       scanHelper.on('discoveredDevice', deviceDiscoveredCallback);

6. Start scanning

   scanHelper.discoverAll();

7. Done!
