What GPS should I use?

The currently recommended unit is the VK-172. The RY835AI chip has some stability issues with GPS, and the AHRS is not working yet.

How should I wire the RY835AI GPS/AHRS chipset?

Wire your chip up as follows:

• RY835AI -> Pi
  1. VDD -> PIN 02 (power)
  2. GND -> PIN 06 (power)
  3. SDA1 -> PIN 03 (AHRS)
  4. SCL1 -> PIN 05 (AHRS)
  5. TXD -> PIN 10 (GPS)
  6. RXD -> PIN 08 (GPS)

Is AHRS working? Can I use Stratux to power [my EFB]'s synthetic vision?

No. AHRS functionality is partial at best, but under development.

Are you sure AHRS doesn't work? It seems fine on the ground as I wave my Stratux around.

Positive. AHRS does not work in flight. Coordinated turns will read as climbs, because the needed code to blend sensor data is not yet working.

How do I view Stratux status? How do I change Stratux settings?

Visit the status page by connecting to the Stratux Wifi hotspot and visiting http://192.168.10.1 in a browser. You can view status (traffic, weather, GPS) and change configurations.
