FIG. 14.23 HC-06 Bluetooth module.
• built-in antenna
• default communication: 9600 baud, 8 data bits, no parity, 1 stop bit
• signal coverage 30ft
• four-pin module
Fig. 14.24 shows the project circuit diagram. The TX and RX pins of HC-06 are connected to
UART RX (PA_10) and UART TX (PA_9) pins of the development board. Two LEDs are
connected to GPIO pins PC_0 and PC_1 with the names 1 and 2.
14.5.5 The Construction
As shown in Fig. 14.25, the project was constructed on a breadboard and connections made
to the development board using jumper wires.
14.5.6 The PDL
Fig. 14.26 shows the program PDL.
