请问解决了吗?
readBLECharacteristicValue中缺少特征值对象// 监听特征值变化 console.log('开始监听特征值变化'); wx.onBLECharacteristicValueChange(function (res) { // console.log(`characteristic ${res.characteristicId} has changed, now is ${res.value}`); console.log("==============onBLECharacteristicValueChange================"); console.log(res); }); setInterval(function () { wx.readBLECharacteristicValue({ deviceId: deviceId, serviceId: serviceId, characteristicId: characteristicId, success: function (res) { // console.log('readBLECharacteristicValue:', res.characteristic.value) console.log("==============readBLECharacteristicValue================"); console.log(res); // console.log('成功'); }, fail: function (res) { // console.log("失败"); }, complete: function (res) { // console.log("完成"); } }) }, 2000); 红色代码部分报错,经蓝色代码部分调试后发现不存在开发文档中的characteristic对象
