ACM Instrument Cluster V0.95

This version focuses on implementing Bluetooth phone connectivity and all associated logic and interface items. Connectivity will focus on phone call handling, contact sync, text message notification display and music streaming.

Emphasis will be set on ease of use and simplicity, automatic error correction with usual Bluetooth connection issues and connection restoration/recovery without user interaction.

Firmware development is continuing based on LVGL, CAN and processor intercommunication standards. Firmware updates will be provided in a separate series, from the firmware team.
