我也排查了一两天，最后一个不经意的测试，让我发现问题所在。我用网上找的蓝牙助手去发命令，HBulider调试器竟然收到广播信息了，那说明我接收本身写的没有问题。 之前我也加了type:'notification'，还有plus.bluetooth.onBLECharacteristicValueChange这种写法，其实这些都可以不用加，只要正常的写法writeType: 'writeNoResponse' 即可了 问题就在于写命令出错了，虽然返回写成功了。贴上我调试的代码吧 // 写命令+接收广播消息 var bufferstr = this.string2buffer(this.writeCmd); uni.writeBLECharacteristicValue({ deviceId, serviceId, characteristicId, value: bufferstr, writeType: 'writeNoResponse', success: res => { console.log('writeBLECharacteristicValue:success:' + JSON.stringify(res)); setTimeout(() => { uni.onBLECharacteristicValueChange(res => { let buffer = res.value; let dataView = new DataView(buffer); let dataResult = []; for (let i = 0; i < dataView.byteLength; i++) { dataResult.push(dataView.getUint8(i).toString(16)); } const result = dataResult; console.log('onBLECharacteristicValueChange:success:OK:', result); }); }, 500); }, fail: err => { console.log('writeBLECharacteristicValue:error:' + JSON.stringify(err)); } }); string2buffer: function(str) { // 首先将字符串转为16进制 let val = str; // 将16进制转化为ArrayBuffer return new Uint8Array( val.match(/[\da-f]{2}/gi).map(function(h) { return parseInt(h, 16); })).buffer; }
