Hi, I’m looking into purchasing 2 SparkPNT FPX (one with tilt) to use as a base and rover for on site survey. Before doing so, I had the following questions: How do you go about “linking” 2 units via the Lora radio included in theses to receive rtk fix on the rover? I would assume the answer is ye…

How do you go about “linking” 2 units via the Lora radio included in theses to receive rtk fix on the rover? PaulZC covered most of this, but the nuts and bolts: You enable the radio on both units via the Web Config. Once a device is set to base (via Web Config or serial commands) it will begin g…

Can the new Facet FP be used as a RTK base station for a DJI drone like the Matrice 4? I know the DJI drones can get corrections via Ntrip but I dont really understand if that means ANY Ntrip capable device. I searched in here and google for “using sparkfun RTK as base for drone” but only really fou…

@georgewalter - Welcome! Bast Caster mode is what you are looking for. Our device is setup on the ground, over a known point. It then begins broadcasting a WiFi access point with an IP and open TCP port on 2101. The DJI controller/drone should be instructed to connected to NTRIP Caster at 192.168.4.…

Thank you. I’m a farmer not a professional surveyor and I’m just looking for an economical way to make some accurate aerial imagery of my land for my own use. Also would like to start RTK mapping things like underground waterlines, cables, etc. so I can easily find that stuff for repairs or when I’m…

[image] georgewalter: To do that with the Facet I need to also set up a dedicated RTK base station correct? The answer is not straight forward. If you have a known location on your land (stake, monument, rebar nail) that you can locate your temporary base over, then you deploy the base over t…

I set the facet to Base Caster Mode and connected the drone controller to the wifi network it broadcast. In the controller Ntrip settings I put in 192.168.4.1 and port 2101, but it also requires a User, Password, and Mountpoint. Are there default values for these when in Base Caster mode?

If your controller requires it, enter anything it will take. The RTK Everywhere firmware does not check the inbound connections against a ‘good’ user/pw.

I entered “1111” for User, Password, and Mountpoint. By doing this it allowed me to save the Ntrip connection in the drone controllers settings but I was never able to get an RTK fix on the drone. I’ll try setting the Facet up as an Ntrip server via the internet and see if that makes a difference.

I cannot get the Config mode to work. It shows the SSID and IP on the display but no device I’ve tried can see a “RTK Config A39E06” Wifi network. [IMG_2575]

Can you connect to the device over Bluetooth? I ask because WiFi and Bluetooth use the same antenna. The WiFi operates at 2.4GHz, so other devices that are using higher frequencies won’t be able to see the RTK device. If Web Config over WiFi continues to be a challenge, consider Bluetooth or Seria…
