Hi, I need a Bluetooth slave module added to my project and HC-05 or HC-06 will do the job. Which one to pick? Given the same price, HC-06 offers less functionality. What are the reasons one wants to pick HC-06 over HC-05?
We recommend the HC-05 for almost every use over the HC-06 because the HC-05 is able to operate in both master and slave mode, whereas the HC-06 can only operate in slave mode, and for almost the same price, the HC-05 is the clear winner.
