I just bought an UART bluetooth module,
I want to build circuit that turn led on and off but I don't know how.
Also I don't know how to connect this module to any physical device and how can I get the result of what that I send via the computer (I see the device as COM4)
It's possible to connect the TX and RX legs of the module to a regular COM port (TX and RX Legs)?
I will be happy to get any kind of help.
Thank you very much,
