In reply to Joseph. Some vendors called it HC-06. But don't worry. If you buy HC-06 or HC-05, they will both work.

I tried your Amazon link, in your “Reviews – HC-05 Bluetooth Module”.
It took me to an Amazon page for an HC-06 module.
What is the difference between the HC-05 and the HC-06?

In reply to akshay. The 05, 04 or 06 is the number of pins that the modules comes with. All modules will work exactly the same, but some come with more pins.

In reply to Rui Santos. Thanks for your reply. Yeah, I think the adapter provides enough amperage. And I've also tried powering it by the DC port, also I tried powering directly through the Vin port, but none of these works.

Hi Rui, I like your projects very much 🙂 . Recently I’ve bought an HC-05 module to work with arduino, android and lcd. I wrote a simple program to receive string from my android phone using bluetooth and print it directly on the 16×2 lcd. Everything works fine as long as the arduino is powered from my PC. As soon as I disconnect from PC and power externally (even through USB), it won’t work. Every time I send something…some erroneous characters comes up on the lcd. Can you help me out?

Hi
I am working on a project that involves making use of a bluetooth. But I am confused between HC 05 and RN42 I/RM module. Can anyone tell me which one I should go ahead with? Since I am designing a product I would want the module to be efficient and at the same time easily programmable.
