What is OBEX protocol? OBEX (abbreviation of OBject EXchange) is a communications protocol that facilitates binary transfers between Bluetooth enabled devices. Originally specified for Infrared Communications, it has since been adopted to Bluetooth and is utilized by a variety of different profiles such as OPP, FTP, PBAP and MAP. It is used for both file

What is WPA3 Security? WPA3, also known as Wi-Fi Protected Access 3,represents the latest generation of mainstream security in wireless networks. Compared to the popular WPA2 standard (released in 2004), it increases the level of security while maintaining backward compatibility. The WPA3 standard will encrypt all data on public Wi-Fi networks and can further protect unsecured Wi-Fi networks.

Wi-Fi 6, which refers to the 6th generation of wireless networking technology. Compared with the 5th generation, the first feature is the speed increase, the network connection speed increased 1.4 times. The second is technological innovation. The application of OFDM orthogonal Frequency division multiplexing technology and MU-MIMO technology enables Wi-Fi 6 to provide stable network

In recent years, the market share of Bluetooth modules has been increasing. However, there are still many customers who are completely unaware of the certification information of the Bluetooth module. Below we will introduce several well-known Bluetooth certifications: 1. BQB certification Bluetooth certification is BQB certification. In short, if your product has Bluetooth function and is
