esp-01s wifi node esp8266 node setup (bug search notes in addition to already available guides)

ESP-01S esp8266 board programming from arduino

  1. usb-to-serial converter – connect rx to tx; tx to rx; gnd to gnd and vpp to both cnp and vcc (or whatever. you need an y cable to do that
  2. don’t trust putty. use termite, set flow control to none, speed 115200
  3. connecting to power will send you “ready”;
  4. AT+GMR gives

-If you type, you should see echo if RX and TX connected correctly (meaning you see what you type) but if CN+p or whatever enable pin is not high, you won’t get answer to other commands

-for programming GPIO0 should be grounded so make Y of the ground cable

-If grounded, you don’t see anything on termite, disconnect gpio0 gnd if you want to see something

-blinky does not work as default, the esp-01 relay v4.0 example works

arduino gui: add the json for the esps, select default esp8266, check serial port, programmer is not important option, do not touch too much

start upload. if communication fails, check comms without gpio0 shorted to ground, and SHORT IT before uploading. upload should make esp-01s make short blue flashes, and in short term some good messages. 7% appeared instantly other lines at the same time about 1 minute afterwards

Hard resetting via RTS pin…

now disconnect gnd to gpio0

reset the board by disconnecting power and reconnecting

Connecting to
WiFi connected
Server started
Use this URL to connect: http://10./

all in just 5-10 seconds. now you can work on more advanced projects.
