Communicating via HC-12

So far, we have learned about various communication technologies that require that we connect to a gateway to send and receive data over long distances. There are situations in which we don’t have access to a gateway and are also not in a position to set one up. That is where HC-12 could come in handy. Using HC-12 modules, we can communicate at a distance of up to 1 km outdoors.

In this chapter, we are going to cover the following main topics:

• Learning about HC-12
• Acquiring HC-12 modules
• Setting up our hardware
• Sending and receiving data

Let’s begin by listing what you will need to complete this chapter.
