ESP32 BLE scan problem!!!
Posted: Sun Sep 30, 2018 3:55 pm
Hello, I´m testing my new ESP32 dev board. I´m trying of to modify BLE Scan example... This sketch return a list of devices avaibles... I would like launch a action (pinout) if ESP32 detect a concret Device. I have tryed some ways but all times return errors... Someone could help me for fixing it?
This is the code:
Thanks!!
This is the code:
