PixRacer with Ardupilot

Posted by Randy on February 9, 2016 at 4:47pm

This is a discussion to focus the feedback and support of ardupilot on the PixRacer board from AUAV.co.

We believe that all teething problems encountered are now resolved and so we recommend people load Copter-3.3.4 which is available for all multicopters through the Mission Planner's (and other GCS's) Install Firmware screens. Note that because regular Pixhawks are still on Copter-3.3.3 the install icon may show Copter-3.3.3 but rest assured, Copter-3.3.4 will be installed (you can check the version by looking at the very top of the Mission Planner).

    The ESP8266 FW works with ArduPilot on Pixracer. No issues. Just plugged in and go.

      I must be doing something wrong. The ESP8266 does broadcast the PixRacer network and allows wifi connection giving out DHCP. I can ping it fine but I can't connect with MP or Tower and when I do a port scan I find nothing open. Are there parameters in arducopter that need setting to enable it?

        Re-wifi.... I did a lot of messing around and I can connect [ with data ] only with the PX4 code I can't connect [with data ] with amp code. It connects... but no data transfer. It's not QGC or APM P2 it's something with the amp code... as near as I can tell anyway. And on a side note even when it's working I don't have a baro reading. Via usb the baro shows fine via wifi it doesn't.

        Did you set the connection to UDP in mission planner?

        Yes, i specified port 14550 and it just waits for a UDP connection. It appears that MP expects the Pixracer to already be sending to that port. I can only assume that it knows the IP address since it gave it out via DHCP. What am I missing?

        There no connection with UDP. It just a bucket to put data in. No data, empty bucket. When you connect to the pixracer access point. It detect the connection. Sends the ip allocated to that device and starts sending the data to that IP address.
        
        I think the issue is that the wifi module is not connected to data. I don't know what port it's on. I tried wiring a ESP7 to telem 2. But that also didn't work and I ran out if time to test. The same module works on a Pixhawk.
        
        Hopefully I get some time later to understand what's up.
        
        What version of ESP FW are you using?

        Gus should be back in a couple days. If still not worked out, ping him on qgc github channel to help out.

        I don't think it's just you and I think their working on it.

      I have not found that to be the case, either with Mission Planner or QGroundControl. PX4 on QGroundControl on the other hand connects consistently any time the Pixracer WiFi network is connected.
      
      Happy to hack deeper via console/terminal/TCP/UDP to sort out what is happening, because this has consistently been the case for me. I have switched back and forth between PX4 and ArduPilot a number of times.
      
      Cheers.
