Bluetooth LE Stack Customization

With the introduction of Android 4.2, updates to the system replaced the in-kernel Bluetooth stack (BlueZ) with Broadcom’s new implementation developed in userspace.  To push the boundaries of this new implementation, cozybit modified the open source stack to include a custom profile, test its operability with BlueZ and iOS Bluetooth, and to identify its performance bottlenecks.

cozybit works with many different wireless technologies such as Bluetooth, Bluetooth LE, NFC, and WiFi just name a few.  We work with these technologies at all layers of the stack to provide complete vertical solutions.  cozybit recognizes that Bluetooth LE is a wireless standard that it coming into its prime, and we’re ready to develop new and exciting products using this technology.
