Hi all. This is my first experience with the ESP8266 and my first post. I ordered an Open-Smart WiFi v1.0 module from China. It has an ESP-07, ceramic antenna and 5 to3.3V voltaga regulator on board. It has a slide switch program-uart and reset button and the board only has 4 pins: 5V, GND, RX and TX. This should be a suitable board for newbies like me because it only has 4 pins, is easy to program and foolproof because of the 5V.
According to several video’s and article on internet I can make direct contact with it using an Arduino Uno and it’s IDE. I put an empty sketch (BareMinimum) on the Arduino, power the ESP8266 an connect RX to RX and TX to TX on the Arduino board, now I can connect to the ESP directly because I am bypassing the AVR of the Arduino.
On power on or reset I get a few garbled characters and then:
IA thinker Technology Co. Ltd.
ready
on the Serial Monitor of the Arduino IDE. Sofar so good. The default speed of this module is 115200 and I want to change that to 9600 baud but when I send an AT command with the Serial Monitor there is no response at all. I have the switch set to UART of course and I double checked all connections. Whenever I press the reset button or reconnect the power I get the welcome message again on the serial monitor. But it does not respond to any of my AT commands.
I had another Arduino board and I tried that but the result is exactly the same: no response to my AT command.
Somehow I can read the ESP’s output but it does not seem to receive my commands, or at least it does not respond to it. Any suggestions on what to do? Can I change the speed from a sketch or is there something I should check first? I hope someone can give me some advise.
