I tried searching this but could not find a good explination.
What program do I need to use and how do I go about logging into the Navio using SSH so I can download the APM Files?
This is my first navio and I have the image up and running on the board and can use a keyboard to type things in, however, it was mentioned it is best to log in using an SSH.
I configured the WPA Supplicant file to use our network, but, not sure what to do next.
I normally also set the interfaces file up so the wlan0 is set one static IP and the eth0 another so it doesnât matter if the LAN cable is plugged in or it is using WiFi.
Whatever you do donât make the Pi visible outside the LAN. Also I would strongly recommend changing the default pi password to something secure.
How do I look up the IP Address assigned to the raspberry pi?
Ok, I found it by typing âhostname -iâ but when i try to connect it says connection refused.
To setup the wifi dongle I go to that wpa supplicant file and open it with notebook and change the SSID=âEMLIDâ to the name of my server and the password as well, correct?
You could look it up in the dhcp client table of your router.
For android their is an app called âFingâ. It scans your network and displays all devices found in it, with IP adresses.
The same thing for Windows would be âThe Dudeâ for example.
I use Fing too on tablet / phone, very useful. Otherwise connect to your router via the PC and check what devices are connected.
If your network is set to not broadcast its SID you will need to add scan_ssid=1 to the wpa_supplicant.conf file. Also make sure you have the correct authentication method set.
When logged into RPi type ifconfig to get the assigned network IP, router address etc, etc as per the link above.
Fing normally works though. You could set up the ethernet (eth0) to be static IP and leave Wifi to be dhcp (dynamic IP).
I ended up just plugging the Ethernet cable in directly and configuring with a keyboard. I got the Navio+ into Arduplane firmware as the navio light is now flashing yellow, however, I can not seem to get it to connect with my GCS. I am using RFD900 Radios to make the connection.
I have tried the default IP Address and my Computers specific IP Address but neither has worked.
I got my computer IP address from doing âWhats my Ip addressâ on google for the GCS. Is this sufficient?
I donât understand why it needs the IP address of the computer if I am connecting through telemetry radios. Is there something else I have to change to use the telemetry radios?
Whatâs my IP will give the external IP address that the internet sees, which is the IP address given via your internet provider.
APM will be wanting the ip of your GCS machine on your local network.
If using telemetry radios shouldnât need IP. However, I found today telemetry connected to UART didnât work but USB did (not found out why yet). Also, you will need to specify baud of 57500 (or whatever it is closest) on GCS side for radios. Found on RPI had to start APM using -C /dev/ttyUSB0 to also get same baud rate (see my previous question re telemetry answered by @schuermannsebastian).
Yes, I get the same crazy message when trying to connect via UART on the main -A telemetry output. I donât understand how so few are using UART for the primary radio link, When you are flying, how is everyone maintaining telemetry over WIFI?
Can it be easily setup with a 3g or 4g dongle and connect via UDP that way?
Man, I can not win with this thing. The manual is horribly vague for someone who is not used to linux.
Now I can not get it to autostart Arduplane.
I open up the rc.local file and add the âsudo ArduPlane -C /dev/ttyUSB0â line before Exit0 and it does nothing.
When I open it back up to see what happenes, the rc.local file is back to normal and the command line that I wrote and saved is completely gone. I donât know what iâm doing wrong here now.
On my rover I have connected the telemetry radio to USB. You do not have to use the UART. It is just convinient, if you used a pixhawk before, because the connectors are the same.
How do we choose which firmware for the Navio+ to run?
The firmware that was installed for Arduplane was 3.3.0 Beta1
I would like to run 3.3.0 Beta2 as it has a few new features that I want and should be released as stable very shortly. Also, once 3.3.0 stable is released, how do I load that firmware onto the navio?
If you want the latest firmware, you will have to compile from source. I just noticed the navio branch is still ArduCopter 3.3-dev (or rc1), so I compiled from âgit clone GitHub - ArduPilot/ardupilot: ArduPlane, ArduCopter, ArduRover, ArduSub sourceâ instead of the emlid repository.
I now have ArduCopter 3.3-rc3 running on my RPi/Navio+.
You can just follow the manual in the docs, just replace the repository with the one I mentioned above.
âgit checkout navioâ is not necessary.
