Utilize SparkFun RTK location data on multiple tablets

Kits
1

I have SW maps working great with my RTK Surveyor and Express. I have an android tablet that works great with SW Maps and I can mock location for other apps, but the camera on the tablet is low quality. I have an iPad which has a sufficient camera but imported shapefile lines don’t show up on it and the location doesn’t get provided to other apps. I’d like to be able to utilize the RTK location on the android tablet and my android phone simultaneously but I can’t seem to get that figured out. The phone battery won’t hold out long enough to use exclusively. I’ve tried a GPS bluetooth broadcaster app on the tablet to send the location to the phone but it doesn’t seem to transmit the mock location data correctly, only the internal tablet GPS.

Does anyone have a method for providing location data to multiple end devices from a Sparkfun RTK unit?

Thanks

If your SparkFun RTK Surveyor supports NTRIP (Networked Transport of RTCM via Internet Protocol) correction data, you could set up an NTRIP caster to broadcast correction data over the internet. Both your Android tablet and phone could then connect to the NTRIP caster to receive accurate RTK corrections. This approach would require an active internet connection on both devices.

You mentioned trying a GPS Bluetooth broadcaster app, but it didn’t work as expected. Instead of using a generic GPS broadcaster app, consider using a dedicated Bluetooth GPS receiver that is compatible with Android devices. These devices are designed to broadcast accurate GPS data over Bluetooth, and they may work more reliably for your setup.

If you have some programming skills, you could develop a custom Android app that reads RTK correction data from the SparkFun RTK Surveyor and then shares it with other apps on the same device, as well as transmitting it to other devices over a local network connection. This would give you more control over how the data is shared and could potentially overcome compatibility issues.

Create a local Wi-Fi or Bluetooth network between your tablet and phone. Develop a custom app or use an existing app that can share location data over this local network connection. This way, you can have one device acting as the “server” that receives accurate RTK data from the SparkFun RTK Surveyor and then shares it with the other devices on the network.

Since you’ve mentioned that you can mock location on your Android tablet, explore different GPS mocking apps available on the Google Play Store. Some apps might provide more accurate and reliable GPS mocking capabilities that can be used across multiple apps.

Keep in mind that achieving accurate and synchronized RTK data sharing across different devices might require a combination of hardware, software, and networking solutions. It’s possible that you might need to experiment with different approaches to find the one that works best for your specific setup and requirements.](What Type of Serve Is Used in Pickleball?)
