Abstract

To address the problems of dependence on laptops, a wide variety of serial cables, and the numerous parameters of dedicated debugging software during on-site maintenance of Automatic Weather Stations (AWS) in outdoor environments, this paper designs and implements a portable, low-cost debugging system based on the Android platform and Bluetooth communication technology. The system consists of an Android application and an RS232-to-Bluetooth hardware module. It uses the Bluetooth SPP protocol to enable wireless serial communication between the Android terminal and the AWS data logger. Device pairing, data transmission, and command parsing are realized through BluetoothAdapter device discovery and BluetoothSocket RFCOMM connection. The system is tested on a DZZ4 AWS in a real outdoor environment, and the results show that the average connection time is less than 30 s, the communication success rate reaches 100% within 15 m in open areas, the average response latency for a single command is 142 ms, and no abnormal disconnection occurs during 8 hours of continuous operation. With its cable-free design and intuitive operation, the system effectively improves the efficiency of outdoor support for meteorological equipment and provides a feasible technical reference for the application of mobile terminal technology in industrial field debugging.
