September 4, 2013: Featured on Hackaday. In this guide, I will explain how to use Arduino to change the settings of the ubiquitous HC-05 Bluetooth module using the AT command set. The HC-05 comes with a rich set of AT commands to perform various tasks such as changing the module’s default settings including changing the pass code, the device name, and the baud rate. But the process of switching the HC-05 into AT command mode for first time users of the module is not straight forward and the docs takes short cuts.
There are a couple of ways to do this. I have picked the one I think is the easiest I will do my best to illustrate the process in simple to follow steps. You can find the full set of AT commands in the attached datasheet. The HC-05 Bluetooth module and its siblings are by far the most popular and inexpensive Bluetooth modules used for RF communications by microcontroller hackers.
10 on ebay and it’s easy to implement. I have published two guides based on the HC-05 Bluetooth module. In both cases, the default settings for the HC-05 were fine. In the process of using the HC-05 for a project, I ran into a situation where I needed to change the defaults for the module. For example, the default baud rate on the HC-05 is 9600.
That’s slow for high-speed transmission. The HC-05 can go as high as 1382400 baud rate according to the HC-05 reference. Also, the HC-05 has a default device name of HC-05. Having two or more of those devices in the same area can be confusing.
