Hello, I have been trying to make an app to control a led using arduino and hc-05 but whenever I try to do the bluetooth configuration am unable to do it. I have made 2 buttons (On and Off) where one will send 1 to arduino and off would send 0 to arduino so can anyone help me in making the blocks section? + when am using the transmit string function using bluetooth so what do i have to put in the characteristic uuid
device name
hc-05
Sorry if I confused you but device name is the UUID
For Bluetooth configuration, ensure the buttons send ‘1’ for On and ‘0’ for Off to Arduino. Use characteristic UUID when transmitting strings.
