Project 1 – configuring the Bluetooth modules

To communicate with the HC-05 Bluetooth module, we will use the same SoftwareSerial library that we used in Chapter 20, Bluetooth LE. The code that is used to communicate is very similar between the HM-10 (Bluetooth LE) and the HC-05 (Bluetooth Classic). How the two radios transmit and receive the data is a lot different, therefore understanding how the radios work and what they should be used for will define when to use the different technologies.

For this first project, we will be writing an application that will allow us to configure the Bluetooth modules. This code will start off exactly as we did with the Bluetooth LE code by including the SoftwareSerial library and creating an instance of ...
