9/23/2023 0 Comments Arduino bluetooth code![]() ![]() The master mode is not common in every Bluetooth module. To use the module as a master, it should be in command mode. By using a default password, the device will connect. At default mode, the HC-05 BT will act as a slave. AT+ORGL – This will set the save command to the module that the setting has been done.īoth modes help the module to act as a Master and a Slave.AT+VERSION? – It will show the version of the Bluetooth module of Responder.AT+UART= *****, *, * – To set the baud rate, stop and parity bit.AT+NAME= ****** – To set/change the device name.Then following commands will help to change the settings of the HC-05. After entering in to command mode the default setting of the module is changeable. The command mode only communicates at 38400 baud rates. The data will be transfer to 9600 which is the default one but it is changeable too. ![]() The baud rate will define within the microcontroller. The data will be transfer with the baud rate. TX will interface with RX of the controller and RX will interface with TX of the microcontroller. The module has two serial input pins, both will interface for data communication. The use of the HC-05 Bluetooth module is simple for every microcontroller, even for every system which has a serial communication interface.
