New Releases v1.0.0
- Add support to STM32 boards with built-in Ethernet, ENC28J60 or W5x00 Ethernet shields
- This is the new library, adding to the current Blynk_WiFiManager. It’s designed to help you eliminate
hardcodingyour Blynk credentials inSTM32boards using with Ethernet (Built-in, W5100, W5200, W5500, ENC28J60, etc). It’s currently not supporting SSL and can not saved config dada to non-volatile memory (EEPROM, battery-saved SRAM, SPIFFS, etc.). To be fixed in future releases. - You can update Blynk Credentials any time you need to change via Configure Portal. Data to be saved in configurable locations in EEPROM.
This library currently supports
- STM32 boards with built-in Ethernet such as :
- Nucleo-144 (F429ZI, F767ZI)
- Discovery (STM32F746G-DISCOVERY)
- All STM32 Boards with Built-in Ethernet, See How To Use Built-in Ethernet
- STM32 boards (with 64+K Flash) running ENC28J60 shields
- STM32 boards (with 64+K Flash) running W5x00 shields
So, how it works?
If no valid config data are stored in EEPROM, it will switch to Configuration Mode . Connect to access point at the IP address displayed on Terminal or Router’s DHCP server as in the following picture:
After you connected to, for example, 192.168.2.113 , the Browser will display the following picture:
Enter your credentials (Blynk Server and Port). If you prefer static IP, input it (for example 192.168.2.113 ) in the corresponding field. Otherwise, just leave it blank or nothing .
Then click Save . After the board auto-restarted, you will see if it’s connected to your Blynk server successfully as in the following picture:
