ESP32 chipID
is now correct and unique. The previous releases' 32-bit wrong chipID
is mainly the 24-bit Organizational Unique Identifier
(OUI) plus 8 bits from the correct chipID. That's why ESP_getChipId()
function can return duplicated values if the boards are from the same batch.
For example
Chip_ID_64 : 0x98F4AB085288
chipOUI : 0x98F4AB
chipId : 0x85288
getEfuseMac: 0x885208ABF498
If you have used one of the full-fledge WiFiManagers such as :
and have to write complicated callback functions to save custom parameters in SPIFFS/LittleFS/EEPROM, you'd appreciate the simplicity of this Light-Weight Credentials / WiFiManager.
This is a Credentials / WiFi Connection Manager for ESP32 and ESP8266 boards, permitting the addition of custom parameters to be configured in Config Portal. The parameters then will be saved automatically, without the complicated callback functions to handle data saving / retrieving.
You can also specify DHCP HostName, static AP and STA IP. Use much less memory compared to full-fledge WiFiManager. Config Portal will be auto-adjusted to match the number of dynamic custom parameters. Credentials are saved in LittleFS, SPIFFS or EEPROM.
The web configuration portal, served from the ESP32/ESP8266 WiFi
is operating as an access point (AP) with configurable static IP address or use default IP Address of 192.168.4.1
New recent features:
This ESP_WiFiManager_Lite library currently supports these following boards:
Arduino IDE 1.8.19+
for Arduino. ESP32 Core 2.0.6+
for ESP32-based boards. ESP8266 Core 3.1.1+
for ESP8266-based boards. . SPIFFS is deprecated from ESP8266 core 2.7.1+, to use LittleFS. ESP_DoubleResetDetector v1.3.2+
if using DRD feature. To install, check .ESP_MultiResetDetector v1.3.2+
if using MRD feature. To install, check .LittleFS_esp32 v1.0.6+
for ESP32-based boards using LittleFS with ESP32 core v1.0.5-. To install, check . Notice: This LittleFS_esp32 library
has been integrated to Arduino ESP32 core v1.0.6+ and you don't need to install it if using ESP32 core v1.0.6+The best and easiest way is to use Arduino Library Manager
. Search for ESP_WiFiManager_Lite, then select / install the latest version.
You can also use this link for more detailed instructions.
ESP_WiFiManager_Lite-main.zip
.ESP_WiFiManager_Lite-main
directory ESP_WiFiManager_Lite-main
folder to Arduino libraries' directory such as ~/Arduino/libraries/
.From esp32 core v1.0.6+, LittleFS_esp32 v1.0.6
has been included and this step is not necessary anymore.
In Platform IO, to fix the error when using LittleFS_esp32 v1.0
for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line
from
//#define CONFIG_LITTLEFS_FOR_IDF_3_2 /* For old IDF - like in release 1.0.4 */
to
#define CONFIG_LITTLEFS_FOR_IDF_3_2 /* For old IDF - like in release 1.0.4 */
It's advisable to use the latest LittleFS_esp32 v1.0.5+
to avoid the issue.
Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'
Please have a look at ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.
ADC1
controls ADC function for pins GPIO32-GPIO39ADC2
controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27Look in file adc_common.c
In
ADC2
, there're two locks used for different cases:
lock shared with app and Wi-Fi: ESP32: When Wi-Fi using the
ADC2
, we assume it will never stop, so app checks the lock and returns immediately if failed. ESP32S2: The controller's control over theADC
is determined by the arbiter. There is no need to control by lock.lock shared between tasks: when several tasks sharing the
ADC2
, we want to guarantee all the requests will be handled. Since conversions are short (about 31us), app returns the lock very soon, we use a spinlock to stand there waiting to do conversions one by one.adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.
ADC2
for other functions, we have to acquire complicated firmware locks and very difficult to doADC2
with WiFi/BlueTooth (BT/BLE).ADC1
, and pins GPIO32-GPIO39ADC2
(GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use the fix mentioned at the end of ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).ESP32/ESP8266 WiFi
will start a WiFi configuration portal when powered up, but has no valid stored Credentials or can't connect to WiFi APs after a pre-determined time.ESP32/ESP8266 WiFi
will try to connect. If successful, the dynamic DHCP and/or configured static IP address will be displayed in the configuration portal. ESP32/ESP8266 WiFi
Config Portal network and Web Server will shutdown to return control to the sketch code.// Must be before #include <ESP_WiFiManager_Lite.h>

The manual input of SSIDs is default enabled, so that users can input arbitrary SSID, not only from the scanned list. This is for the sample use-cases in which users can input the known SSIDs of another place, then send the boards to that place. The boards can connect to WiFi without users entering Config Portal to re-configure.
// To disable manually input SSID, only from a scanned SSID lists
#define MANUAL_SSID_INPUT_ALLOWED false
This is for normal use-cases in which users can only select an SSID from a scanned list of SSIDs to avoid typo mistakes and/or security.
The maximum number of SSIDs in the list is seletable from 2 to 15. If invalid number of SSIDs is selected, the default number of 10 will be used.

.
Check retries block the main loop #18
#define MAX_NUM_WIFI_RECON_TRIES_PER_LOOP 2
Default is no interval between reconnection WiFi times if lost WiFi. Max permitted interval will be 10mins.
Uncomment to use. Be careful, WiFi reconnection will be delayed if using this method.
Only use whenever urgent tasks in loop() can't be delayed. But if so, it's better you have to rewrite your code, e.g. using higher priority tasks.
Check retries block the main loop #18
#define WIFI_RECON_INTERVAL 30000 // 30s
Default is true
. Just change to false
to not using Board_Name
on Config_Portal
In Configuration Portal Mode
, it starts an AP called ESP_ABCDEF
. Connect to it using the configurable password
you can define in the code. For example, MyESP_ABCDEF
(see examples):
After you connected, please, go to http://192.168.4.1 or newly configured AP IP, you'll see this Main
page:
Enter your credentials,
Enter your credentials,
or
then click Save
.
The WiFi Credentials will be saved and the board connect to the selected WiFi AP.
If you're already connected to a listed WiFi AP and don't want to change anything, just select Exit
from the Main
page to reboot the board and connect to the previously-stored AP. The WiFi Credentials are still intact.
