ESP8266 | ESP8266 WiFi module Library for Arduino

I reviewed many solutions and did not find a suitable example.

I have a certain selection

Using a Expressif dev-board and standard micropython.bin I was able to create a littlefs2 partition, mount it and write data into a file:

I'm doing this on esp8266 with micro python and there is a way to clear OLED display in Arduino but I don't know how to clear display in micropython i used ssd1306 library to control my OLED

and this is my error I've written a code that prints on OLED from a list loop, but OLED prints it on the text that was printed before it (print one on top of the other not clear and printing) 7

Hope you're doing fine! I'm starting to learn about setting up WebServers on ESP8266, so, I'm developing this small project to start into it.

Basically, it's a WebServer with my ESP8266 working as a AP, where I input an HTML form with 6 input values that I'll receive on my ESP8266.

At this point, I've 2 big problems:

1st and most important, the server, the HTML script, & the AP work well overall, since once I upload the code on the ESP8266, and connect to the AP, I can access the form with no issues ( http://192.168.4.1/ ). The problem comes when I input the values and click "SET" to submit them, because it just prints: Not found: /action_page.php

I don't know where's the issue, I tried setting some code lines to redirect the acces if the server is not found, but it didn't even accessed the main page.

2nd, my serial monitor doesn't print any line in this code, with other codes, it prints normally, but this one doen't do it. So I don't know wat I'm doing wrong.

I'll appreciate any advice, thanks in advance! This is my current code:

Looks like I broke my NodeMCU Lolin esp8266 module, please confirm)

Firstly everything worked fine, but then...

1. I uploaded a bit strange boot.py to play with UART0

I built a couple of test IoT hardware devices for home automation which I want to control with an Android app I also wrote. The app will be used by several people.

My plan is to use Amazon IoT Core to let the apps send MQTT commands to the IoT devices.

Since my hardware devices are not very powerful (ESP8266 architecture) I'm going to authenticate via the Signature Version 4 (SigV4) scheme. This auth scheme is useful when the hardware device is not powerful enough to authenticate via the standard privatekey/certificate method; it requires a pair of key/secret IAM credentials to be hardcoded into the device firmware (instead of the certificate and private key).

I then created a test "thing" in the IoT Core console and I can successfully send commands from the apps to the devices (and receive data from the devices and show them on the apps).

My question is, do I need to create as many "things" as the IoT devices? Since each device will have its own IAM credentials, can I just use one shared "thing" for all the IoT devices?

I can't find any best practice online, not even on the official documentation.

I'm trying to print the return value(WiFi.localIP) on my display from the library ESP8266WiFi. But I'm getting an error. For the display I'm using the SSD1306 library.

The purpose of this is to print the IP adress of the ESP8266 on the display.

After I used VSCode (current version 1.61.0) and the Arduino IDE (1.8.13 / 1.8.16 - WIndows installer version) for about a year on two Windows 10 devices both devices stopped showing available Arduino / ESP8266 board types yesterday.

The Arduino board configuration only shows one item "Selected Board:" with an empty drop down.

The Arduino IDE on both devices still works (Tools - Boards show the familiar collection of boards)

My settings (searched for Arduino) are

Hope you're doing well. Im developing a proyect where I need to upload many variables to Google Spreadsheets, for what I'm using IFTTT, which only let me upload 3 values apart from the event name and the upload date.

So, I figured out that to upload more values to my Google Sheet, I'd only need two out of the three values, because I will upload all the variables separated by commas in the slot reserved for "value 1", and a Google Sheet/Excel command to separate it in many cells after uploading them in "value 2".

I tried an example of this in the WebHooks documentation page in IFTTT, and it worked, the problem comes when I create the jsonObject in Arduino IDE, since the code complies and get uploaded to my ESP8266, but in the serial monitor, show me the following error.

Seems line a syntax issue, I tried changing (and deleting) characters like "{", "}", but the issues continue, what could be causing this?

The code to create the jsonOject is this:
