WiFi connection manager for ESP32 and ESP8266 with OLED support

WiFiConnect

WiFi Manager for ESP8266 and ESP32 chips with support for OLED 128x64 screens

Overview

This is a wifi manager based upon the popular WiFi Manager . I created this project as I was finding that wifi managers were not fully supporting my needs or the ESP32 and I has just bought a Heltec ESP32 WiFi kit with onboard OLED display, I decided to extend and modify WiFiManager to my needs.

WiFiConnect can be used when no screen is needed and WiFiConnectOLED for feedback to the user via an OLED display.

I'm using a customised font definition Roboto_Font.h that was generated with the help of the online tool http://oleddisplay.squix.ch/ I have also customised a version of ESP8266_SSD1306 version 4, available here to use my Roboto font by default and prevent the default font from being loaded into memory. If you decide to use the origional library, please remove #define OLEDDISPLAYFONTS_h from the Robotto font file. The origional version is available at ESP8266_SSD1306

wificonnect's Issues

ArduinoOTA makes WiFiConnect fail to remember WiFi settings

Prerequisites

• Can you reproduce the problem in safe mode?
• [x ] Are you running the latest version?
• Did a recent dependancy update cause the problem?
• Are you reporting to the correct repository?
• Did you perform a cursory search?

For more information, see the CONTRIBUTING guide.

Description

Have tried the ArduinoOTA >> BasicOTA example that comes with the ESP8266 arduino core. The OTA function works as expected, however after trying to revert to normal USB cable based flashing of a sketch utilizing WiFiConnectLite the ESP8266 always boots up in AP mode where one can select the Access point and store the password. Serial monitor tells those data get stored but then the ESP8266 reboots and can not connect to the AP, and falls back to STA mode again.
(WifiConnectLite repo does not have its own issue tracking)

After running a sketch utilizing WiFiManager to configure the AP credentials, we can revert back to the sketch utilizing WiFiConnectLite and the ESP8266 will boot in STA as expected.

Steps to Reproduce

1. Upload the ArduinoOTA >> BasicOTA example to your ESP8266 via USB
2. Upload the ArduinoOTA >> BasicOTA example to your ESP8266 via WiFi
3. Upload a previously working sketch utilizing WiFiConnectLite via USB
4. ESP8266 will always end up in STA mode and will not connect to the AP even after saving the credentials
5. Upload a sketch using WiFiManager via USB, configure AP credentials
6. After reboot ESP8266 will now connect to the AP
7. Upload the sketch utilizing WiFiConnectLite via USB. Will work again this time

Versions

BasicAutoConnect doesn't compile.

Firstly, fantastic library. This is the best of the ESP WiFi management libraries around I think.

However, when opening the 'BasicAutoConnect' example without any modifications on an ESP8266, trying to compile results in:

In file included from C:\Users\Anonymous\Documents\Arduino\libraries\WiFiConnect\src\WiFiConnectOLED.cpp:32:0:

C:\Users\Anonymous\Documents\Arduino\libraries\WiFiConnect\src\WiFiConnectOLED.h:37:25: fatal error: OLEDDisplay.h: No such file or directory

 #include "OLEDDisplay.h"

                         ^

compilation terminated

To resole this issue. I have to delete the WiFiConnectOLED.* files and then it compiles.

Would you have any idea why the Arduino compiler is picking up these files even though they aren't linked?

APNAME

Newbie here, not so much a feature request. A quick question. Where can I change the AP name. I was rummaging through the WiFiConnect header file but not quite sure how to change it.
Thanks for the library, appreciate it.
