This video show you how to connect your HC12 module to and Arduino UNO and changing the set up using the Serial Monitor.

We will take a look at how to change the Transmit power (dBm), channel, baud rate and mode. This will influence the range. I'll also show you how to see the current settings of a module and how to put it back in default mode. FU4 mode and FU3 mode is best for long range.
