Wire my hc-06 to arduino UNO r3


I am having trouble connecting my hc-06 Blue Tooth module to my computer. When I search for blue tooth devices it can find the device but when I try to connect it will connect for about 2 seconds then disconnect. I've seen other people have had this issue and I've tried the suggestions from other forums but they have not worked. I attached pictures of the module wired to my arduino R3.

Connect HC06 Vcc to Uno 5V, not 3.3V.

At least while developing code, open a software serial port, connect the HC06 to the software port. Use the hardware port for program upload, program monitoring and troubleshooting.

You may need a higher capacity battery as well. 9V smoke alarm batteries are pretty weak.

Using 5v has not worked either. And what would you recomend I use to power it instead of the 9v battery

The HC-06 uses 3.3V logic and requires level shifters to connect to the Uno. If you connected it without using level shifters, one or both may have already been damaged.

Notice the "LEVEL 3.3V" printed on the back of the board, in the posted photo.

Follow Martyn Currey's tutorial carefully.

Sorry I have not had time to interact with the forum but I have noticed that my hc-06 can connect to an app on my phone but not other apps on the same phone or to my computer does anyone know why this would be the case?
