This is tool for configuring and communicationg with cheap Bluetooth modules HC-05. This firmware was mainly tested on Arduino Nano but should work on any Arduino.
- echo - run echo server. It is useful to check if your module is working. You run this command, connect to the module with your phone or PC and start sending some text to it. The module will receive the text, send it to Arduino, Arduino will send it back to the module and then module will send it back to you.
- atmode - switch HC-05 into AT command mode. The Arduino will just into
serial passtrhogh device between your PC and HC-05. This allow you to
communicate with Bluetooth module without any additional hardware (with the
exception of Arduino of course). You can test if it works by sending
ATcommand which should be answered withOK. - master <MAC-of-slave> <name> <baudrate> - configure connected HC-05 module as
Bluetooth master. It has two parameters. The first one is MAC address of the
bluetooth device to which you want your module to connect immediately after
boot. Note that MAC address should be in the following form
1234:12:123456- not like classical one with lot of:. The second parameter is just Bluetooth name of your HC-05 module. Pretty useful to distinguish it from other HC-05 slaves. The last argument isbaudrateof the UART. - slave <name> <baudrate> - configure connected HC-05 module as Bluetooth
slave. The same as for master you can configured name of the module. The last
argument is
baudrateof the UART. - name <name> - change Bluetooth name of the module.
- baudrate <baudrate> - change baudrate of the module. This baudrate is used when module communicates with Arduino.
