This protocol is an efficient wireless communication protocol independently developed by Fanlun, addressing industry pain points through underlying architectural innovation. The solution adopts a flattened protocol design that condenses the traditional five-layer OSI upper-layer protocol stack into a single layer, eliminating unnecessary packet header addition and parsing processes to achieve direct data pass-through transmission. It supports one-to-many and many-to-many connection modes, enabling up to 20 devices to form a network for communication. A unique window synchronization mechanism greatly reduces power consumption at the receiving end, lowering device power consumption by 80% while maintaining millisecond-level response. The protocol has built-in encryption mechanisms based on ECDH and AES to ensure data transmission security. It can coexist with Wi-Fi and Bluetooth LE without requiring additional spectrum allocation. The solution provides complete SDK and API documentation and supports Fanlun's full series of Wi-Fi SoCs, covering multiple generations and product series, enabling developers to complete prototype development within 2 weeks. Two typical applications include: a coin-cell battery wireless switch (no gateway required, with a single coin-cell battery lasting over 2 years) and a Wi-Fi remote control (millisecond-level response, control range of 100 m+).
