以下是以上鏈接介紹的簡單列子
Here is a very simple example, showing a button:
<button id="the-button">Try it</button>
…and the following JavaScript:
const button = document.querySelector('#the-button');
button.addEventListener('click', function() {
navigator.bluetooth.requestDevice({
filters: [{
services: ['battery_service']
}]
}).then(device => {
console.log('Got device:', device.name);
console.log('id:', device.id);
});
});
As mentioned earlier, the method navigator.bluetooth.requestDevice() can only be called in response to a user action like a button click. This method calls up a dialog box showing the list of available BLE devices matching the query filter. In our case, the filter we have set pertains to BLE devices which expose a so-called “GATT service” called battery_service. We’ll find out more about GATT services in the next section.
可試下

解決了嗎？我的需求是設備要通過藍牙向手機app發送資料，不知道咋整，還無從下手，不知道用不用連接，還是直接監聽轉載請註明出處，本文鏈接：https://www.uj5u.com/qianduan/45459.html
