How to do a Device to Device Update on the Mammut Barryvox S - Avalanche Safety Solutions

Device-to-device Update Instructions

This new function allows upgrades to the BarryHeart 3.2 firmware to be made from one device to another. This makes it possible to run the firmware upgrade even where there is no access to a network or service point - very easily from device to device.


You must update to and from the same type of device (i.e. Barryvox to Barryvox or Barryvox S to Barryvox S.)

Both Barryvox devices have a battery capacity of over 30%. Only one simultaneous upgrade is possible between two devices in the same building or within a radius of 50 meters.

Upgrade must take place between devices utilizing the same W-Link region (no device-to-device upgrade for devices purchased in Japan).
