PIXHAWK & Telemetry

Help / Getting Started
1

Hello

My config:
Air 1:

  • Raspberry PiZero & openHD v2.0.8
  • CSI Camera
  • Pixhawk 2.4.8 & latest Arduplane version
  • UART connection for telemetry (telem 1)
  • AWUS036NH with BEC

Air 2:

  • Raspberry Pi3 B & openHD v2.0.8
  • CSI Camera
  • Pixhawk 2.4.8 & latest Arduplane version
  • UART connection for telemetry (telem 1)
  • AWUS036NH with BEC

Air 3:

  • Raspberry Pi3 B & openHD v2.0.8
  • CSI Camera
  • PixracerR15 & latest Arduplane version
  • UART connection for telemetry (telem 1)
  • AWUS036NH with BEC

Ground:

  • Raspberry Pi3 B & openHD v2.0.8
  • CSI Camera
  • Pixhawk 2.4.8 & latest Arduplane version
  • AWUS036NH with BEC
  • HOTSPOT wifi configuration

openhd-settings: ( only change )
RC=mavlink
TELEMETRY_TRANSMISSION=wbc
TELEMETRY_UPLINK=mavlink
FC_RC_SERIALPORT=/dev/serial0
FC_RC_BAUDRATE=57600
FC_TELEMETRY_SERIALPORT=/dev/serial0
FC_TELEMETRY_BAUDRATE=57600

Config files Arduplane
SERIAL1_BAUD = 57600
SERIAL1_PROTOCOL = MAVLINK1 ( tested with MAVLINK2 )
SR1_ADSB=5
SR1_EXT_STAT=2
SR1_EXTRA1=4
SR1_EXTRA2=4
SR1_EXTRA3=2
SR1_PARAMS=10
SR1_POSITION=2
SR1_RAW_CTRL=0
SR1_RAW_SENS=2
SR1_RC_CHAN=2

I correctly made the connection to the various configurations.
When I start the whole thing, I have the video feedback, the OSD works and displays the telemetry data, but if I connect to the wifi hotspot, with my smartphone or my computer, then Qgrouncontrol tells me:

“Vehicle 1 did not respond to request for parameters…”

And that does not matter what AIR configuration I use, namely I did not touch anything while it was working under EZWifibroadcast.
Do you have any idea where the problem comes from?

Thank you
( sorry for my bad english, translate witch google :stuck_out_tongue: )

( my config with Gimbal Storm32 3axis et arducam with zoom & IR filter )

The problem is a bug with my adapter wifi.

i have a solution, connect two Wifi adapter on the ground, and the telemetry work on Qgroundcontrol

Hello! Is that arducam zoom module on the gimbal connected to open HD? If so how is the zoom controlled? I was interested in using a zoom camera module through open HD

I am using an arducam ptz which has an i2C connector to control the focal length and focus.

I have programmed an attiny85 which translates the PWM signal to i2C and I am using 3 zoom levels from a 3pos switch on the radio.

This camera is in 1080

That’s awesome!! Thank you, that may be the solution to my zoom camera plan

6

I have another idea which will be to use 2 cameras with different focal length lenses and switch from one to the other

Yup I plan to do that, however not really sure how I can add a 2nd IP camera to a Pi3A with only one usb port. Thought of using a hub perhaps, or maybe there’s a way through the gpio pin
