HC-05 Bluetooth. Arduino. Change baud rate 38400. Send random to app - Internet of Things - MIT App Inventor Community

Hello friends, To carry out applications with Bluetooth between Arduino and App Inventor, the HC-06 module is usually used. This module can only work as a client, enough for most of the projects that you will see in the tutorials, it is the most used and recommended. Default 9600. Another similar module is the HC-05, this can function as a server or a client. You may have to set the speed using AT commands to adapt it to App Inventor. It comes with 38400 baud and you will have to change it
