RT-Thread source code(RT-Thread is an open source IoT operating system from China, which has strong scalability: from a tiny kernel running on a tiny core, for example ARM Cortex-M0, or Cortex-M3/4/7, to a rich feature system running on MIPS32, ARM C

the existing 802.11 standards can be optimized (especially in terms of energy-efficiency) to make Wi- Fi suitable for a wide range of IoT applications. However, there is a lack of low-cost embedded platforms that can be used for experimentation wi
