Firmware can be upgraded on most of the Kontakt.io devices. This way we can introduce new functionality and improvements to existing beacons. Firmware upgrades are free and available to all customers.
Since Kontakt.io devices are based on different chipsets and have different sets of features, they usually have different firmware that is designed specifically for them.
All devices that use nRF51 chipset (Smart Beacon SB16-2, Tough Beacon TB15-1, USB Beacon UB16-2) share the same firmware, since their hardware platform is identical. They all have the same firmware version numbers.
The only beacon based on the DA14580 chipset - Card Tag CT16-2 - shares the same firmware versions as nRF51-based devices. Underneath, of course, there is a separate firmware specific to the Card Tag CT16-2 functionality. However, the most important limitation of this beacon is that its firmware cannot be upgraded.
All nRF52-based devices have their own firmware, tailored to their functionality. Because of that, firmware versions are completely independent.
When a new firmware version is released, Kio Cloud and our legacy Panel cloud-platform will display information about the firmware upgrade for relevant beacons on the list of devices assigned to the logged in account.
Applying firmware upgrades requires the Kontakt.io Administration App. The upgrade procedure is documented in this support article.
