Application for selection of Bluetooth or WLAN

Wireless communication is important in data transportation between devices. It is as ever important to find the best connection fitted for the users specific requirements. This process can be a hassle and having an application testing all the options could save both time and resources. This project involves solving mentioned problem and to create an application implementing the solution. A method of recommending a connection is to measure different metrics e.g throughput and packet loss for Bluetooth (BT) and each channel on 2.4GHz and 5GHz Wireless Area Network (WLAN). By using an appropriate algorithm to rate the connections a result ranging from best to worst can be displayed to the user. Limitations on metrics can be inputted by the user to tailor the result to match user requirements. The application is based on Hardware Meets Software (HMS) product Anybus Wireless Bridge II. With a Telnet connection Attention-commands (AT-commands) can be used to configure and utilize the modules e.g measure signal strength. Third-party services POCO and iPerf are used to measure other metrics e.g throughput and latency. C++ and Visual Studio was used to develop the application. In accordance to the test specification the projected resulted in a successfully working application. Tests prove that with interference on a channel results in a worse rating and that other channels that are unaffected gets a higher ranking on the list. There is still room for improvement regarding exception handling when connection timeouts happen due to loss of signal
