Firmware upgrade delivers heightened security levels

Evolution can be applied to all luminaires, drivers and lighting control devices based on the Nordic Semiconductor nRF52 chip, across the Casambi ecosystem.

When upgrading, all network settings are maintained. The optional Evolution firmware upgrade joins the company’s existing Classic firmware which continues to be supported.

“This latest Evolution firmware upgrade underlines why the Casambi ecosystem is the de facto Bluetooth lighting control standard,” said Timo Pakkala, co-founder of Casambi. “In addition to delivering advanced capabilities, Evolution demonstrates that Casambi is the leading end-to-end lighting control provider with the most seamless firmware upgrade path.”

Supporting up to eight Pulse Width Modulation (PWM) channels, Evolution offers better operational performance to users, taking advantage of four times more RAM chip memory to store new configuration data, such as additional scenes and timers. The new firmware also delivers an enhanced security model.

With this firmware upgrade, information on the condition and priority level of a Casambi device is now transferred through the Bluetooth mesh network, enabling detailed information to be visible remotely.

This can be used to communicate that it has overheated, for example, or if there is a configuration failure or a missing driver.

Evolution will run on any hardware platform that is based on the nRF52 and currently running Classic firmware version 25.0 or above.

Backwards compatibility is maintained with previous versions of firmware.

While Casambi can manage an unlimited number of luminaires across an unlimited number of networks, the firmware upgrade boosts the number of ‘Casambi Ready’ devices that can operate within each single mesh network from 127 (the number attained when using Casambi’s Classic firmware) to 250 – an increase of more than 96%.
