GeoMotion Sender Release notes

Purchase link and licence detection fixes

• Fixed the in-app "Purchase" button not reaching the purchase page
• Fixed permanent licences being treated as annual (expiring after one year). Keys issued by the website in the GMS-P- / GMS-A- format are now recognised; older GM-P- / GM-A- keys keep working

Location-off guidance and a layout fix

• Shows a warning banner when location services (GPS) are off. Checked on launch and on resume; a guidance dialog appears if GPS stays off
• Also checked when START is pressed: if GPS is off, sending is blocked and you are taken to Settings (with GPS off the receiver could connect but never got a position, which was hard to diagnose)
• Fixed the status bar (clock, icons) overlapping the app title / version on the start screen

Android 16 support

• Targets Android 16 (API 36)
• Build tooling and libraries updated to current stable versions (AGP 8.9.3, Kotlin 2.0.21, JVM 17)

Background power optimisation (heat)

• Idle mode: GPS and sensors stop while no Receiver is connected, start automatically on connect and stop on disconnect
• Sensor rate reduced from ~60 fps to ~5 fps; high-frequency debug logging removed
• Bluetooth accept switched to blocking mode; heartbeat interval changed from 10 s to 30 s

Fixed map heading rotating while stopped

• Fixed the map rotating by about 90° while stopped at lights. When stationary the last GPS bearing is kept instead of the magnetic compass heading
• The tunnel fallback (GPS gap monitor) now keeps the GPS bearing as well

GPS-loss handling in tunnels

• If GPS updates stop for 2 seconds, the last position keeps being sent as a fallback (with gradually degraded accuracy)
• Compass heading from the sensors keeps updating inside tunnels
• Fallback stops automatically when GPS returns, avoiding Google Maps on the receiver getting stuck on "searching for GPS"

Clearer connection status

• Removed the "device selection" UI, which is not needed in SERVER mode
• Connection status now shows three states: Connected (blue) / Waiting for connection... (green) / Stopped (grey)

Bluetooth switched to SERVER mode

• The Sender (phone) now acts as SERVER and the Receiver (head unit) as CLIENT; the Sender waits for the Receiver to connect
• More stable connections in the car

Layout adjustment

• "Send settings" and "Update Frequency" are now side by side to save vertical space

Button placement

• The "Navigation settings" button moved next to the licence information

Permanent licence and navigation settings

• Added support for permanent licences
• Added navigation settings
