Option description:

  • AT firmware means the firmware of the module is AT firmware.
  • TTF means the firmware of the module is transparent transmission  firmware.

Product introduction:

  • TTL-WiFi transparent transmission firmware is developed by Shenzhen Sibo Zhilian Technology Co., Ltd. based on the company's ESP-M2 wireless module, realizing the real-time transparent transmission of module serial port and WiFi data. After our company's painstaking research and development, its firmware functionality and stability have met the industrial level transparent transmission requirements. This firmware greatly optimizes the serial port receiving and transmitting performance. It specially designed the reconnection mechanism in WiFi STA mode and the reconnection mechanism in TCP Client mode to ensure stable connection and transmission of data links.
  • The developed transparent transmission firmware optimizes the web page configuration interface, supports AP, STA, AP+STA configuration mode, supports serial port baud rate from 300bps to 3686400bps, supports TCP Server/Client, UDP Server/Client, UDP LAN broadcast, etc. Features. At the same time compatible with AT command configuration, it is the most cost-effective WiFi transparent transmission product on the market.

Product features:

  • The TTL-WiFi module is based on the development of our ESP-M2 WiFi module, which leads to the serial port TTL, EN, STATE and other pins. The built-in serial port transparent transmission firmware of our company can complete real-time transparent transmission of data from TTL port to WiFi/cloud of the device, with low power consumption control and status indication. This module can directly replace the original wired serial port to realize data acquisition and control of embedded devices.
