Product introduction: The TTL-WiFi transparent transmission firmware is based on ESP-M2 wireless module, realizing the real-time transparent transmission of the module serial port and WiFi data. its firmware functionality and stability have met the industrial level transparent transmission requirements. This firmware has greatly optimized the performance of serial port receiving and sending. In particular, the reconnection mechanism under the WiFi STA mode and the reconnection mechanism under the TCP Client mode have been designed to ensure the stable connection and transmission of data links. The R&D transparent transmission firmware has optimized the webpage configuration interface, support AP, STA, AP+STA configuration, supported serial baud rate from 300bps~3686400bps, supports TCP Server/Client, UDP Server/Client, UDP LAN broadcast, etc. Features. At the same time compatible AT_command configuration is the most cost-effective WiFi transparent transmission products on the market.
Features: The TTL-WiFi module is based on the development of our ESP-M2 WiFi module, which leads out the serial TTL, EN, STATE and other pins. The built-in serial transparent transmission firmware of our company's latest version can achieve real-time transparent transmission of TTL port to WiFi/cloud data of the device, with low power consumption control, status indication and other functions. This module can directly replace the original wired serial port to realize data acquisition and control of embedded devices.
