Review: A Perfect Addition for Controlling Your Micro-Processors with Your Smartphone VIA Bluetooth Communication - Worked Perfectly. This board is a Perfect Companion to the Arduino Family of Micro Processors, and Easily Connects. Allowing one to use their Smartphone to Communicate and Control their Processor of choice. I had No Difficulty in getting the device to work, and although you can change the "Default" Settings, I found that they were suitable for my projects. I am using this particular unit with an Arduino Nano in an "Otto" Robot that I have assembled. And I am using my Cellphone to send commands to My Otto Robot, that really increased the function. The HC-06 Device was Delivered in an AntiStatic Bag and was carefully packaged for shipping. The unit arrived in Brand New Condition without any damage or bent Pins. I was more than pleasantly surprised at the Quality of the Product and the build of the Circuit Board and Attachment of the Chips. A few Connections and the Board Powered up with the Indicating LED's giving firm indication of Operation. DSD Tech did a fine job in delivery and shipping. And the Product was "As" Described. I will Buy Again from them.
Review: Not for beginners - I choose DSD Tech, based on reviews. The product was delivered via USPS, with instructions, inside a padded envelope, inside an desertcart shipping envelope. The HC-05 module has a plastic protective cover. Module worked straight out-of-the "box", but only because I studied several examples prior to beginning. I can see why a person might give up. Testing: The module successfully RECEIVED message . Using Android phone as transmitter and the HC-05 module as receiver, the module was able to receive messages at a distance (of at least) ~15m outdoors, line of sight (15 m was max distance tested). I did not test message transmission. I will buy again (so that I can test transmission).

### ⭐⭐⭐⭐⭐ A Perfect Addition for Controlling Your Micro-Processors with Your Smartphone VIA Bluetooth Communication

### ⭐⭐⭐⭐⭐ They are wise enough to stay with firmware version 2.0-20100601.
*by P***K on June 5, 2021*

You can get HC-05 from a variety of vendors, some at significant discounts, but they typically are flashed with newer firmware versions that are not as robust and proven as the one shipped by DSD-Tech. I recently picked up four HC-05s from another vendor for roughly the same prices as one from DSD-Tech; Connection problems, pairings disappearing, and device crashes on data transfers. I finally bit the bullet, replaced the devices with DSD-Tech modules, and now the system runs flawlessly. No other changes, just changed the HC-05.
