TTL-WiFi transparent transmission firmware is developed by Shenzhen Doctors of Intelligence &
Technology Co., Ltd based on the ESP-M2 wireless WiFi module, which can realize the real-time
transparent transmission between serial and WiFi. After our deep research, the performance of firmware
can be satisfied with industrial requirements on the stability and functionality. In this time, we have
already greatly optimized the receive and transmit performance. Especially, we design the reconnection
mechanisms at STA and TCP Client modes to guarantee the stable connection and transmission for the
data link.
