What is the range of HC-05 Bluetooth module?
It uses the 2.45GHz frequency band. The transfer rate of the data can vary up to 1Mbps and is in range of 10 meters.
How do I fix my HC-05 Bluetooth module?
Step 1: Diagnosing the Issue
- Give VCC and GND connections to your Bluetooth module. I gave 5V from Arduino UNO and used one of the ground.
- Set your DMM to voltage and check the voltage of the regulator as shown in the pic.
- In my case it was 0.6V thats why one of the LED was litting up dim like shown in the pic above.
How do I check my HC-05 Bluetooth Module?
(The easiest way is to see if the RED indicator is blinking). Now, go to the Bluetooth Settings on your phone and pair your phone with the HC-05 Device. The key is 1234. After successfully pairing, open the ArduDroid App and connect with the HC-05 module.

What is en pin on Bluetooth module?
This pin is used to bring the Bluetooth module in AT commands mode. By default, this pin operates in data mode. The Key/EN pin should be high to operate Bluetooth in command mode. In HC-05, the default baud speed in command mode is 38400bps and 9600 in data mode.
What is the maximum range of Bluetooth?
The range of the Bluetooth® connection is approximately 30 feet (10 meters). However, maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. NOTE: Not all audio devices are supplied with Bluetooth capability.
Can Bluetooth range be extended?
A Bluetooth extender helps extend the connection distance, and it can extend your connection up to 100 feet indoors and 300 feet outdoors. They can also boost your signal strength and allow you to connect to multiple devices.
How many types of Bluetooth modules are there?
