HarmonyOS 蓝牙发送大数据导致主线程卡死

在进行蓝牙发送数据时，调用socket.sppWrite时，会卡死

async writeData(clientNumber: number, data: Uint8Array) {
  console.info(`writeData is 向客户端写入数据}`)
  // 向客户端写入数据
  if (this.currentDevice != null && this.currentDevice.isTcpConnected) {
    ConnectTcpClient.get().send(data, (callback => {

    }))
  } else {
    console.info(`socket is sppWrite}`)
    socket.sppWrite(clientNumber, data.buffer);
  }
  let dataStr = ''
  if (data != null) {
    for (const b of data) {
      let str = b.toString(16);
      if (str != null && str.length == 1) {
        str = 0 + str; // 补0
      }
      dataStr += str
    }
  }
  console.info('发送 success data = ' + dataStr);
}
