Nice post!
I'm new to ESP's ...Hello, sir.<br /><br />Nice post!<br /><br />I'm new to ESP's modules, so I want - first - to use one ESP-12-E as WiFi module to Arduino. I've searched a lot of information, but I did not find the proper wiring to maintain serial communication between arduino and ESP. Some wiring examples shows different GPIO's configurations. I've tried all of them, but I'm still unable to send or receive information between Arduino and ESP. With this configuration you showed, the ESP LED blinks strong once, when powered UP. With another configuration the LED blinks very faded once.<br /><br />So, what might be going wrong? I'm using a logic level converter between Arduino and ESP TX/RX. All wires are placed correctly. I'm using sketches that other people tested... <br /><br />Is There a debug of the led behaviour on boot, or may I condemn my ESP module?<br /><br />Thank you!<br /><br />Best regards,<br />Tiago.Tiago Araújohttps://www.blogger.com/profile/10350292680303461053noreply@blogger.comtag:blogger.com,1999:blog-3466508970473354894.post-9409256223148064312016-06-16T03:12:10.204+02:002016-06-16T03:12:10.204+02:00Thanks man, you made my experience with this modul...Thanks man, you made my experience with this module really smoothNahuelhttps://www.blogger.com/profile/14677508564589804528noreply@blogger.comtag:blogger.com,1999:blog-3466508970473354894.post-12298766427013265172016-05-13T16:01:04.567+02:002016-05-13T16:01:04.567+02:00Have you tried ESPLORER as a terminal/IDE software...Have you tried ESPLORER as a terminal/IDE software?<br />http://esp8266.ru/esplorer/<br />ARehttps://www.blogger.com/profile/13473291183033725832noreply@blogger.comtag:blogger.com,1999:blog-3466508970473354894.post-55272029090153940922016-05-07T23:03:55.949+02:002016-05-07T23:03:55.949+02:00Hello,

I am using OESPP FTDI serial adapter to flash the module. I have connected the Tx, Rx and GND to Rx, Tx and GND respectively. When i open the COM port and click reset i was able to see the output from the Wi-Fi module on the screen. <br /><br />My module came preflashed with NodeMCU. It said Node MCu version 5.1.4 and then init.lua not found. There is a > and i am not able to type anything on the screen. When i click reset, i get the same message. I am still unable to type anything on screen. <br /><br />My serial adapter is in 3.3V configuration. I tried 5V configuration too. It's still the same. I am using arduino to upload the program.

I can now use the AT command set and it works. Yippy. I would have never thought to jump gpio15 to ground.
