I'm trying to make a weather station. I bought the esp-05 version of the 8266 wifi module. And I cant get it to connect to the internet. I'm not sure if the module works or not.
How can I check if it connected correct and working?
Can I borrow a piece of code that is confirmed to get the module out on the internet?
Place you're code between code tags </>
https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966
Check under Files ->Examples for sample code. After you get that running add your changes.
bit vauge! what have you attempted?
as @oldcurmudgeon recommends try some examples - if they don't work upload details of the problems
Ok.. i have tried to find a way to confirm if the module is installed correct or not.
I have no idea if its even alive or dead.
I have tried this code among many.
*------------------------------------------------------------------------
Simple ESP8266 test. Requires SoftwareSerial and an ESP8266 that's been
flashed with recent 'AT' firmware operating at 9600 baud. Only tested
w/Adafruit-programmed modules: https://www.adafruit.com/product/2282
The ESP8266 is a 3.3V device. Safe operation with 5V devices (most
Arduino boards) requires a logic-level shifter for TX and RX signals.

I get this in my serial monitor
" Adafruit ESP8266 Demo
Hard reset...'
no response from module."
have a look at ESP8266-testing
upload a schematic showing how you have wired up the module
Hi
I have seen your page .. I have connected just as you
my monitor is not quite like yours i get a lot of squares when I clear the monitor, when i place the cursor in the field for writing messages, and when I start the program/reset the arduino board.
I can print text tho so i can read the messages i presume
When I write AT only the long line of sqaures come up and same with the others... I dont get an OK
sounds like you may have the incorrect baud rate set in the serial monitor - check it is what is in setup()
That is the one i have chosen. and to confirm it i try to make a serial.print and that i can read fine
have a read of how-to-get-the-best-out-of-this-forum
in particular avoid images of text screen output - it wastes space, difficult to read one cannot copy code for testing - copy and upload the text
can you post a link to the actual board you have?
upload a schematic showing how you have wired up the module
@horace the screenshot was to show you the message window, and not the code.
The board is the one you use on the page, and its wired the same as yours on the homepage
Only my arduino board is not the duo but a mega2560 card
