As the product matures, new features and bugfixes are made available in the form of firmware updates. This page will be updated to include the latest Firmware version, the changes that were made in that version, and older releases for historical purposes.

Releases below are compatible with all BlueBus units, regardless of hardware revision.
NOTE: Release notes include changes made in versions 1.1.19, 1.2.0, 1.2.1, 1.2.2, 1.2.3 and 1.2.4, none of which are going to be released for public use due to bugs
Comfort
Add ability to automatically turn off the OnBoard Monitor (Navigation Screen) after you set off driving
Add ability to control volume offset in calls so that we can get rid of the "flicker" when changing call volume. NOTE: This kills the ability to update volume on the fly for calls on E8xs
CD53 / MID / MIR
Resolved an issue causing crashes during metadata scrolling due to lack of null termination on string
Back Ported all available settings to the UI
Added ability to disable metadata scrolling.
Enhance verbiage of settings
Resolved an issue with endless UI updates when using the unit with the MIR (Monochrome Navigation)
BMBT/VM
Resolved issues identifying video modules
Do not display Album information on dashboard when it is not provided
Removed useless Mic Bias setting
General Improvements
Add Support for Hardware Version 2.0!
Refactor single line menu code so that it is shared between the CD5x, MIR, MID and IRIS.
Improve the BM83 connection logic to make it connect more quickly and more reliably.
General Bug Fixes
Resolved Issue with Hardware 2.0 and certain DSP amplifiers not working correctly during telephone functions. If you're having this issue, toggle "Settings > DSP > Mode" to "TCU".
Terminate diagnostics explicitly when all "special" lighting should be disabled to prevent certain Light Modules from continuing to keep the given bulb on
Resolved an issue where the "Music" App on iOS would not update the Metadata beyond the first song
Resolved an issue that caused TEL_MUTE to be pulled high at boot on HW 1.x variants
Resolved an issue with the byte queue for the BC127 BT module that sometimes caused data loss
Releases below are NOT compatible with hardware version 2.x! (NOTE: Hardware revision can be identified by the color of the power LED. Green indicates HW 1.x, and Blue indicates HW 2.x)
Resolve issues identifying early Navis (MKI, MKII) and video modules
Convert non supported chars into ASCII, while keeping as much working on BMBT
Change CD to Disc 1 again for BMBT
Ambient and Oil Temperature (Non-M, Non-E46/E8x cars only!) on BMBT
Remove "BT" in headers
Support for Fahrenheit, auto configuration of unit based on cluster settings
Add Dashboard OBC setting to display temperatures in BlueBus Dashboard display
General Improvements
Refactor lighting code to work in a timer so we can keep lamps turned on indefinitely
Add Estonian Language Support
Add Itlanian Language Support
Refactor trap catches
Set custom Class Of Device, as used by BMW cars usually, adding Car-Audio minor device specs
Add Unicode normalization for accented characters, check for buffer overruns
On HFP connection, initialize expected character set to UTF-8 (standard defines 7-bit IRA encoding by default) to enable iPhones to send extended chars in Caller-ID
Explicitly request sending Caller ID on connection.
Add PBAP profile support
Allow Users to override DSP Amp input source
Announce CDC on boot to prevent issues with radio detection of CDC
Store multiple configuration values in one byte for temperature settings
Wait for 15ms before rebooting into bootloader so that the debug message is not cut off
General Bug Fixes
Set char queue to 0 on instantiation to ensure the state of the data (to prevent trash from causing issues)
Fix Caller ID memory leak
Add Unicode normalization for accented characters, check for buffer overruns
Add additional checks to ensure we do not query the LM when the ignition is off
Split I/K-Bus module ping requests to prevent flooding the I/K-Bus with frames when the car initializes (Prevents bug that stops visual and audible notification of unlock on LCM III/LCM IV)
Align buffer sizes across the application to ensure memory safety
Correctly utilize snprintf() and strncpy() to ensure we are not leaving memory on the table, or missing NULL termination
Fix issues with PDC / R Gear detection for volume lowering
For "Digital" Audio Users (DSP Amplifier), calls are now fielded using that interface regardless of radio mode for improved quality
Set max volume offset to 12 steps
Fix issues with Caller ID for contacts with spaces in the name
BMBT
Resolve incompatibility issue with TV Module by listening to
0x4E
command
Add language support to UI. RU, ES, EN, NL and DE languages are avaiable.
CD53
Add Caller ID Support
Add Support support for dynamic comfort blinkers (1-8 blinks)
Fix "2" button on newer CD53s in E8x cars
Enhance Detection of CD53. It is a known issue that upon first installation, the BlueBus will not display a UI on a CD53 until the second time the car/BlueBus wake up.
MID
Add Support support for dynamic comfort blinkers (1-8 blinks)
Uncategorized
Fix CDC status/state emulation to prevent track number and playback issues
Change Device Name Length to 64 bytes
Add BLE/MAP profiles to BC127 library
Catch and log BC127 module boot failures
Add Self Play (Radio Control of CD Changer) ability for cars without an I-Bus Changer
Complete rework of the lighting activation functionality. Lighting I/O status is now only requested when the dimmer state changes OR if we have gone more than 20 seconds without seeing the I/O status. This is different than before as I used to request I/O status every time the dimmer status was seen, but requesting the I/O status resulted in another dimmer status update (which caused an avalanche of messages). Further, code was added (kindly by another contributor to the project) to identify the particular LCM/LSZ variant and send the appropriate values in the bulb activation request
A bug that caused the E46/Z4 IKE to dim out when using turn signals during the day has been resolved
Cyrillic character transliteration has been added (by another contributor). This also includes the angled quotation marks that many iPhone's like to use (which should fix how your iPhone's name is displayed on screen).
The DAC is now powered down at boot, then it is powered back on shortly after. This should hopefully clear the condition that causes the I-Bus impulses to be audible at every volume level.
The I-Bus message queue is now capable of firing off more than one message at a time (which was a bug).
