What Connection Type Should I Use and How Do I Change It?

If your Garmin® device supports secure connections for accessories, you may want to change the sensor connection type between Open and Secure. 

For more information on the differences between Open and Secure connection types, and a list of device that support secure connections, see .

NOTICE: To switch connection types for an accessory already paired with your watch or Edge® cycling computer, first delete the current connection. Then, you can add it again using the new connection type

Below are Garmin accessories that support open and secure connection. Choose one to reveal instructions on how to switch connection types.

HRM 200

Tip: Hold the HRM in your hands so you can easily see the button (1) and LED (2). (The HRM will only go to sleep after two minutes of not being worn and no button presses.)

• Ensure the HRM is awake by pressing the button once.

• The LED will blink green to indicate it is awake:

  • Double-blink: Secure connection type

  • Triple-blink: Open connection type

• To change the connection type, double-press the button.

You can pair your HRM with your device once more. If pairing while in secure mode, put the HRM in pairing mode. See How Do I Enable Pairing Mode on My HRM? for more information.

What Connection Type Should I Use?

The secure connection is a good choice if you plan to connect your  accessory to one or two newer Garmin devices that support secure connections,  for more info see . When the accessory is set to use the Secure connection type (LED blinking twice), only devices capable of making secure connections can find it.

If you plan to use your accessory with older Garmin devices, third party apps, or fitness equipment, set it to use the open connection type (LED blinks three times), otherwise it may not be found, or connectable, by older Garmin devices, fitness equipment, or most third party apps.
