ESP8266 Community Forum Arduino: How to send int array with ESP8266 http post request?Helpful? Please support me on Patreon: 3 – the ESP8266 gets the request and switches the LED. 336 bytes): ESP8266 responds with: After that, send the actual request as follows: ! Note: PHP POST method with ESP8266 12 July 2017, 08:00 PM. but a simple version could simply skip ESP8266/NodeMCU Source Code. but a simple version could simply skip To do a simple test you can use, as described, a program like Postman, and you must create a POST request Postman POST Request example As you can see we specify a raw body in JSON format, and we receive a status 201 (Created to simulate an add of a room on Database) and a JSON response with status “OK”. const char* ssid = "WiFi_SSID" //Enter Wi-Fi SSID. At the end of this ESP8266 tutorial, you learned how to build an ESP8266 Web server to build HTML UI pages.

Also change POST request data as per your server requirements. While (WiFi.Esp8266 post request The http url is: ESP8266 WiFi – HTTP POST request maken (ArduinoIDE). Go to Python’s official website and download 2.7.x (specific release) for Windows (MSI installer)

In order to use OTA functionality, you need to install the Python 2.7.x version, if not already installed on your machine.

Upload New Sketch Over-The-AirNow, you can upload new sketches to the ESP8266 from Arduino IDE over-the-air.

It’s a mandatory step, so that you’re able to do the next updates/uploads over-the-air.

Upload Basic OTA Firmware SeriallyUpload the sketch containing OTA firmware serially.

Install Python 2.7.x seriesThe first step is to install Python 2.7.x series in your computer.

The only disadvantage is that you have to add an extra code for OTA with every sketch you upload, so that you’re able to use OTA in the next update. One important feature of OTA is that one central location can send an update to multiple ESPs sharing same network. It helps reduce the amount of time spent for updating each ESP module at the time of maintenance. OTA functionality is extremely useful in case of no physical access to the ESP module. The OTA programming allows updating/uploading a new program to ESP8266 using Wi-Fi instead of requiring the user to connect the ESP8266 to a computer via USB to perform the update. This is known as Over-The-Air (OTA) programming.

A fantastic feature of any WiFi-enabled microcontroller like ESP8266 NodeMCU is the ability to update its firmware wirelessly.
