How to put the Sensor into firmware update mode manually

This article explains how to put the Firstbeat Sports Sensor into firmware update mode manually. Use this method when the Sensor factory reset in the Firstbeat Sports: Coach app does not find the Sensor.

Before you start

• Try the Sensor factory reset in the Coach app first. See Solution 6 in Coach app or Athlete app does not find the Sensor.
• Use this method only when the factory reset fails. Expect all measurement data and athlete pairings on the Sensor to be lost.
• Timing is important: release the pins less than 1 second after the LED starts blinking.

Steps

1. Remove the battery. Open the battery cover on the back of the Sensor and remove the battery.
2. Connect the pins. Connect the two metal studs on the Sensor, the analog front end (AFE) pins, to each other and keep them connected. For example, touch both studs with your fingers.
3. Insert the battery. Keep the studs connected and put the battery back. Make sure that the battery does not lose contact again.
4. Wait for the LED. The LED stays on for a few seconds and then starts blinking.
5. Release the pins. As soon as the LED starts blinking, release the studs immediately, within 1 second. The Sensor is now in firmware update mode.

Complete the firmware update

1. Find the Sensor. In the Coach app, open Sensor Management and wait until the Sensor is visible with the status UPDATE MODE. Becoming visible can take some time.
2. Update. Tap the blue microchip icon next to the Sensor and wait for the update to finish.
3. Pair the athlete. Pair the Sensor with the correct athlete profile.

Result

The Sensor has the latest firmware and is paired with the athlete again.
