Read out the MAC address of Polar chest straps (and other BLE devices)

• Download and install the nRF Connect App for Android (iOS cannot read out MAC addresses)

• Keep the Polar device next to you.

Note: Better put other Polar devices further away from you to avoid confusion with an unintentionally activated other Polar device.

• Open the app and tap on “no filter” so that you can filter out unwanted devices

• Adjust the RSSI Threshold further to the left
• confirm with the tick symbol

• press “scan” on the top of the app
• Then keep the Polar device close to the phone and activate it by rubbing the area on the inside of the Polar (A) with slightly wet fingers:

• Once the device turns on, you should see it in the scan list with its MAC address (here F0:BA:E4:78:EE:5F).

Note:

• In the screenshot below, instead of “two” you the name should be “Polar” or whatever device you are looking for.
• If you wait too long, you have to press the “scan” button again.
• Since there is no off button on the Polar devices, bring the current Polar device out of range if you want to read out another one to avoid confusion.
