Dear All:
Please help.
With ESP-32, Wi-Fi network credentials (SSID and password) stored in SD Card with CSV can be read from SD Card. But when I tried to use these two values to connect to local network, ESP-32 can not access to the network. I am new to the programming and can not figure out why. Could you please help me with few lines of codes? Any book or article to read?
Thank you

Hi.
Please check this tutorial: https://randomnerdtutorials.com/esp32-wi-fi-manager-asyncwebserver/
That tutorial uses SPIFFS. But, you can replace the SPIFFS functions with SD card functions, and it should work.
For read/write functions for the SD card, check this example: https://github.com/espressif/arduino-esp32/blob/master/libraries/SD/examples/SD_Test/SD_Test.ino
You’ll see it’s very similar with the SPIFFS functions.
I hope this helps.
Regards,
Sara
