The sample you have in the course ESP32 BLE android application is giving me a problem. I copied it as is and using it successfully the first time i Connect to the ESP32. I can switch on the LED so i know all is well. When I disconnect the BLE service and try to reconnect, it doesn’t connect. I have close the App, turn of Bluetooth on the phone, Switch on Bluetooth. Start the App again and then it will connect again.
Any advice please
It is somewhere in the ESP32 Code. When I use a BLE Scanner App it connects the first time and I can see all the Services and UUID. And serial monitor show temperature value. second time around the BLE scanner can’t connect.
When you try to reconnect, do you get something on the serial monitor about the bluetooth connection?
