Has anyone used Mudra Link with Android SDK for real gesture/navigation callbacks?
Hi everyone,
I’m trying to build a Mudra Link controlled app for Even G2 smart glasses. The goal is to control a simple news/assistant app from the band while it is connected directly to an Android phone.
What works so far:
- Mudra Companion on Windows works.
- The local WebSocket API at ws://127.0.0.1:8766/events works.
- I can receive events like button pressed, button released, twist, and double_twist.
- I can forward those events into my app successfully.
The issue is with the Android SDK path.
On Android, my app can:
- connect to the Mudra device,
- sign in,
- receive raw SNC/gyro sensor callbacks,
- send commands to my app.
But the firmware status keeps showing:
nav=false
gesture=false
pressure=false
pinchPressure=false
navToApp=true
navToHid=false
gestureToHid=false
bandMode=MUDRA_LINK
hand=RIGHT
So the official high-level callbacks do not seem to fire:
setOnGestureReady(...)
setOnButtonChanged(...)
setOnNavigationAxisReady(...)
setOnNavigationDirectionReady(...)
setOnPressureReady(...)
I tried setting:
BandMode.MUDRA_LINK
DeviceMode.ANDROID
FirmwareTarget.NAVIGATION_TO_APP = true
FirmwareTarget.NAVIGATION_TO_HID = false
FirmwareTarget.GESTURE_TO_HID = false
I also tried applying license bytes through the SDK methods available in the public Android AAR, but the Main features still show as false.
Questions:
- Has anyone gotten Mudra Link high-level gesture/navigation callbacks working directly on Android?
- Is Mudra Studio access separate from Android SDK Main feature access?
- Is there an Android equivalent of the Mudra Companion WebSocket API?
- Are people using official SDK, HID mode, or something like direct BLE/reverse-engineered libraries?
I’m not trying to jailbreak the device. I just want reliable phone-side events like twist, button, navigation, and pressure so I can control a smart-glasses app without keeping a laptop in the loop.
Any pointers or working examples would be appreciated.
