Kaleido HiBean BLE Firmware


SnowBear Firmware Installation

Kaleido currently uses Classic Bluetooth to talk to HiBean  a dated standard that, importantly, isn't supported on iOS at all. This project is a workaround that finally brings Kaleido connectivity to iPhones and iPads. It also pairs nicely with Bear's bridge for connecting devices over BLE Serial, which sidesteps the long-standing issues Classic Bluetooth SPP has on macOS, especially on Apple Silicon. Brought to you by Bear of the Skywalker community, with support from Will_Z at HiBean.
