微信小程序蓝牙写数据传值ArrayBuffer
发送代码如下: var buffer1 = new ArrayBuffer(2); var uint8Array = new Uint8Array(buffer1); uint8Array[0]=254; uint8Array[1]=207; wx.writeBLECharacteristicValue({ deviceId: that.data.deviceId, serviceId: that.data.serviceId, characteristicId: that.data.write, value: uint8Array.buffer, 最终提示发送成功,但是发送的数据为空,请问该如何传值,多谢! BTW: 数据封装采用官方提供的: let buffer = new ArrayBuffer(2) let object = new DataView(buffer) object.setUint8(0, 254) object.setUint8(1, 207) 将value:buffer 此种方式也是行不通。
