I'm working on a robotic arm project. But I want to try to connect one of the servo on the robotic arm via bluetooth HC-05. I found the method at https://www.instructables.com/Arduino-How-to-Control-Servo-Motor-Via-Bluetooth-w/
I've made an application at MIT according to the web. However, when I connect bluetooth via MIT App Inventor 2 on my android, I always get the message "Error 516: Unable to Write: Broken pipe". How to fix it? Please help me
Is there something wrong with the blocks?
fyi. I have tried from several sources that say that the error can be fixed by connect, disconnect, and then reconnect the bluetooth in the application. But, it doesn't work for me
