Just few words about flashing ESP-Link on ESP8266 (I posted first working on the ESP01 but gave it up. It bugs a lot. I use now a 4 Mbyte version.)

Yesterday I was looking (bit lazy) to make an ESP8266 TCP / Serial bridge in order to remote control one of my Nextion screen with Node-red (development and testing only).

While browsing I found out ESP-Link. Very nice tool. (Pity, I found that too late)

So, in few steps, to flash it you need to:

  • Download ESP-Link flasher software
