• HC-05 is not BLE, it is old Bluetooth 2.0, HM-10 is BLE.
    HC-05 is good mainly to connect to another HC-05.
    You can connect it to PC but via older rfcomm protocol, that adds another COM port but it is a bit of hassle. After PC is set up with new COM port paired to your HC-05 you can use serial connection in IDE
