Here will come the installation tutorial of the device, what make a professional device differ from a toys is how you manage it.

important

  1. Do not attempt to do things if you are not aware on what are going to do.
  2. Aircraft profile shall be entered in the setup before any usage
  3. Download the INSTALL MANUAL and FILL it

aircraft setup

  1. When you are on the ground with engine off you need to CALIBRATE the device in Settings
  2. When you fly and the device is not going well BEFORE changing the parameters CAGE it
  3. If you experiment problems: records a video of the landscape view and than go in the screen of the "Vibration Setup", share it to the community and a solution will come

noises

There a dedicated chapter in the https://github.com/xiaprojects/rb-esp/wiki/Shopping-list

parameters

Recommendation to check these values in fly mode with a partner

PAR Description Example value Best value with low noises
OUT FILTER SW LPF from Q-Output 1 is enough, if the pitch or the rolls are jumping up and down needed try 2 or 3 3
ACC FILTER SW LPF of Accelerator sensor 3 is enough, if it is unstable try 6 6
GYR FILTER SW LPF of Gyroscope sensor 3 is enough, if it is unstable try 6 9
Compensation Acc vs Gyro Compensation 230 is fast, if it is unstable try 100 230
Sensor Hz Velocity of Q 20Hz, if you notice the Yaw Degree is not aligned try to increase the Hz 20Hz
Att+GPS GPS Compensate Attitude Shall be enabled, on long term turn it is mandatory to automatically align "precession", also limit the pitch up-down during takeoff Enabled
GYRO DPS Max of Gyroscope 64 Degree per second is of for Attitude 64 DPS
ACC G- Max of Accelerometer 4G is enough for attitude, during the G-Meter this will be automatically increased by settings 4G
GYRO ODR Output data rate Lower this value if you experience wrong behavior 30 DR
ACC ODR Output data rate Lower this value if you experience wrong behavior 30 DR
GYRO LPF HW Low pass filter Lower this value if you experience wrong behavior 0 LPF
ACC LPF HW Low pass filter Lower this value if you experience wrong behavior 0 LPF

barometer

  1. Go in a known altitude "HAS" and calculate at 1013 hPa the altitude (do not use GPS or similar because at 1013 is different)
  2. Move the slider to reflect at 1013 the real height above sea
  3. As per every barometer this action shall be in the maintenance manual every 6 months

gps

  1. Select the baud rate
  2. It shall say "DATA RECEIVED"
  3. If it is not connected please investigate the wiring diagram
  4. Contact Community for support

Reliability

Barometer

Attitude indicator

Power Supply

The RB-02 has an INTERNAL ADC converted which estimates the INTERNAL voltage, if you input +5V from the USB you shall read 4.2. If you power it directly from 12V you shall see 4.4 Volt ... 4.0 Volt. If you go on battery pack you shall read 4.1 Volt ... 3.5 Volt and display may flicker.

SD-Card

The SD-Card shall be formatted in FAT32 and maximun size is 32GB

GPS

Bluetooth RB-05

The RB-05 is using the Bluetooth Connection to existing FLARM-Stratux devices enabled. Before going to attempt to install the RB-05 software, you shall check if your Stratux is already sending the Traffic data to the Bluetooth BLE Channel 0xFFE0 0xFFE1.

Enable Bluetooth on Stratux

  1. Ensure you have up and running the RB-01 or RB-03 or Stratux 1.6 EU (may work on 2.0 PRE USA)
  2. Enable BT in your config.txt (you can find it in /boot/firmware/config.txt) and comment the line #dtoverlay=disable-bt (example of DISABLED bluetooth config.txt)
  3. Enable the BLE 0xFFE0 in stratux.conf file (you can find it in /boot/firmware/stratux.conf)
  "BleOutputs": [
    {
      "Capability": 8,
      "UUIDService": "FFE0",
      "UUIDGatt": "FFE1",
      "Characteristic": {}
    },

Validate Stratux

The validation of this feature can be achieved using your smartphone with any BLE listener app that supports "Notify" on Characteristic. Here you can see a real example of data received: DiagIfYourStratuxHasBluetoothBLEEnabled

Validate RB-05

  1. Once you checked the Stratux has Notify on 0xFFE0
  2. Install the RB-05 binary into the device
  3. Navigate to the latest page going on RIGHT
  4. There is a log of the device which is trying to connect to the Stratux bluetooth device and search of 0xFFE0
  5. If you find Notify Enabled the RB-05 is correctly connected and waiting for traffic

To ask support to the community you shall take a photo of the console log displayed in the [3]

Pre-Requirements RB-05

  1. Name of the device shall be Stratux
  2. Service shall be 0xFFE0 and Characteristic shall be 0xFFE1
  3. Notify shall be available
  4. Stratux shall advertise its name in 30 seconds after RB-05 power on
  5. We noticed that after 50 reconnection the Linux stack (Raspberry Stratux) will not accept anymore any connection, in this case you shall power cycle the Stratux, but is after 50 glitches...
