Sneak peek - The Avee BlueLink MkII

The Avee BlueLink MkII has been making good progress the last few months, and we have succesfully been through an initial test period with ‘first line’ testers. This test has been crucial for us to get as much constructive feedback from the users as possible.

More testing
After the initial test period, we have now made modifications to the design of the BlueLink to include the comments from the testers. 

We are now in for a second test period with ‘first line’ testers and even a ‘second line’ testers. This test will start at the end of this month and run for a few weeks.

Practically this test will still be done on 3D-printed versions of the BlueLink, but with ‘factory produced’ silicone buttons (the buttons on the side of BlueLink). 

The main mold will be set in production on February 21st, and we expect the first factory-produced BlueLink enclosures to be back to us around March 10th.

First BlueLinks shipping
We expect to start shipping the first BlueLinks out to customers by the end of April 2022.
The BlueLink is available for back-order from February 12th.

These images
The images we show here are from our 3D-printed version of the BlueLink.
On these models we use bright colors so it is easy to see problems.

The finished BlueLink will be available in all colors as long as you choose black.

The BlueLink design
Making the BlueLink MkII as simple as possible has been a fundamental goal during this development process.

We got some comments from BlueLink MkI users (the one with the OLED screen) that it was somewhat over-engineered. We have to agree with those comments.

Connecting the BlueLink MkII 

The BlueLink MkII is connected to the aircraft using the standard Avee20 aircraft interface cable used for the Avee microphone.
The reason for using this cable is simple: to keep things as simple and affordable as possible.

  • If you use the BlueLink, plug the Avee20 interface cable into the BlueLink. 
  • If you do not use the BlueLink, plug the Avee20 interface cable into the Avee microphone and tuck away the BlueLink.

The BlueLink is connected to the Avee microphone via a 50cm cable – angled USB C connector in the microphone end and a straight USB C connector in the BlueLink end.

BlueLink user interface
The BlueLink has five keys with a tactile feel easy accessible from its left side.
These five keys are fairly huge (made for big fingers) and make the BlueLink extremely easy to use.
All key presses are acknowledged with audio messages.

Please check out the BlueLink User Manual below for details.

The clip
On the back side of the Avee BlueLink we have added a belt clip.
No explanation needed!

Charging
The BlueLink is charged with a standard USB C cable which is included with the BlueLink.

The Avee BlueLink MkII – User Manual

This is the User Manual for the BlueLink MkII.
Version February 8th – 2022.

Play/pause
Accept & decline call

This key which is found on the top left side of the BlueLink is a combined key, and its function depends on if we are playing music or if we are in an active call or incoming call.

Music mode:

  • Short press (< 500ms) to switch between play/pause
  • Long press (> 500ms) to skip to the next song


Incoming call :

  • Press shortly (< 500ms) to accept.
  • Long press ( > 500ms ) to reject


Active call:

  • Short or long press to hang up

Volume increase
and decrease

The volume keys on the BlueLink will only ajust the Bluetooth volume level.

  • Press + key to increase Bluetooth audio volume
  • Press – key to increase Bluetooth audio volume

Please note:  ATC/intercom audio level is set from the aircraft.

The mute key

The muting functionality is important for us when flying.

On the BlueLink MkII we have three ways or manners (modes) for the Bluetooth mute.

Press the mute key shortly ( < 500ms) to skip between these three modes. A spoken audio message (‘pause mute’, ‘level mute’, ‘mix mute’ (TBD)) is announced by the BlueLink.

Pause mute:

  • Pause mute pauses Bluetooth audio when ATC / intercom audio is detected. Playing music starts automatically 2 (TBD) seconds after ATC/intercom silence. 

Level mute

  • Level mute is partly (0-100%) muted Bluetooth audio when ATC/Intercom is detected.
  • The mute level level can be adjusted with the volume keys within 5 seconds of pressing the mute key. 

Mix mute

  • Mix mute is actually no mute at all.
    Bluetooth audio is mixed with ATC/intercom audio.


Please note: Unfortunately, there is no way the BlueLink can differentiate between ATC calls and intercom calls.
If you set the BlueLink to partially mute the Bluetooth (level mute) , this will be done whenever audio is detected in to the BlueLink.

Volume increase
and decrease

The volume keys on the BlueLink will only ajust the Bluetooth volume level.

  • Press + key to increase Bluetooth audio volume
  • Press – key to increase Bluetooth audio volume

Please note:  ATC/intercom audio level is set from the aircraft.

The on/off key is the bottom debossed key placed on the left side of the Avee BlueLink MkII.
The key has multible functions.

  • Switch on:
    Press the on/off key to switch on.

  • Switch off:
    Press and hold the on/off key for two seconds to switch off.

  • Paring mode:
    Switch on -> Then press and hold on/off key for 1 second.
    A spoken ‘pairing’ is announced by the unit.

Please note:
Please note that the BlueLink is switching on automatically when aircraft avionics (bias voltage) is detected.

The BlueLink is automatically switched off 3 minutes after aircraft bias voltage is not detected
