You can configure a BlueSnap dongle by using a terminal application, such as PuTTY, TeraTerm, or JavaTerm. In this example, we are changing the baud rate of a BlueSnap AAA from the default 115200 to 9600 using PuTTY. Afterward, we will verify the BlueSnap's firmware, then save the configuration.

1. Open PuTTY and select the Serial radio button, choose your COM port, and set the baud rate (by default 115200).

r,1 to save the settings and reboot the device. You should see a return of Reboot!. The green LED should stop blinking on the unit.

Verify the Configuration
To verify the settings we just changed you will need to follow the below steps:
1. Open PuTTY and select the Serial radio button, choose your COM port and set the baud rate to 9600 (note this baud rate is different from the default because we changed it in the previous steps).
