The default baud rate for the BlueSnap Smart Dongle is 115200. Some applications may require a different baud rate. This article will walk you through the steps to change the baud rate (to 9600 in this example).

Open PuTTy, select the Serial radio button and set your communication options to the correct COM port and baud rate. For this example, our USB-RS232 cable is assigned to COM 235 and the BlueSnap Smart Dongle is using the default baud rate 115200. Click Open to be taken to the terminal window.
Once the terminal window opens press the power button on the BlueSnap Smart Dongle to enter COMMAND mode. If you do not see the [COMMAND_MODE] message, close the terminal window, power off the BlueSnap Smart Dongle, re-open the terminal window and press the power button. Contact Serialio if you continue to have issues entering COMMAND mode.
