Application problem with bluetooth projects

Hi my friends, I have a blink project on esp32 bluetooth, but the blink application does not work without a phone connection to the internet. Is there a solution to this problem?

Since Blynk is a “full” IoT process, and requires the use of a Server to link the App and MCU Hardware… then your only real options are…

  • Connect the phone to internet.
  • Make your own Local Server with WiFi AP and connect the phone to it. But this is a much more advanced setup, requiring more advanced abilities.
  • Don’t use Blynk if all you need is a simplistic BT connection between App and Hardware.
  • Use Blynk and WiFi as that is the most prevalent and functional way.
