支付宝小程序(ble 适配android和ios) 入门一
直接把蓝牙相关工具封装js文件,然后通过page页面调用即可
//page功能实现页面
import { scan } from '../../util/bles';
import { openDoor } from '../../util/bles';
const app = getApp();
Page({
// 调试log输出
data: {
text: '',
arr:[]
},
onLoad() {
app.getUserInfo().then(
user => this.setData({
user,
}),
);
},
scanBle () {
const that = this;
// let mAdvertisData = 'asfasfasgdgwerjertjwpejwioejrioweg';
// that.setData({
// text: mAdvertisData.substring(0 , 2) + mAdvertisData.charAt(2),
// })
my.offBluetoothDeviceFound();
my.onBluetoothDeviceFound({
success: (resFound) => {
my.getBluetoothDevices({
success: (resFouned) => {
that.setData({
arr: resFouned.devices,
});
},
});
},
});
scan(function(e){
that.setData({
text:e,
})
});
},
onClickItem (e) {
const that = this;
openDoor(e,function(result){
that.setData({
text:result,
})
})
},
});封装的ble功能js文件(因为涉及保密项目比如门禁,保险柜等,有些数据都是随便写的,改成自己的就行了)
