I plan to (eventually) build my own GCS. So far, I've created a simple COM port rerouter (for sharing a COM port across a network) for my GCS. I will have the APM on the drone (drone is connected to…Continue
"Andreas, we are not using the dronecell. In my opinion it is not capable of transmitting video of good resolution. We are using an onboard computer running Ubuntu. I understand that bandwidth is not an issue, because the size of the telemetry data…"
"The only real benefit of running data through a server is that the GCS could also be connected to the Internet via 3G. That solution would double the latency though.
@ContraSpec: It would work, but the latency would be much higher than a more…"
"Ellis Akins and I are developing our own solution to telemetry and direct control over IP. We have successfully flown a quadrotor with a 3G TCP connection using a tethered Droid (for testing purposes...we will soon switch to 4G modem). Latency times…"
"After many hours of searching, I gave up and started working on something else. Then I stumbled across this completely by accident: "MAVLink is stateless, but QGroundControl tracks if a system is alive using the heartbeat message. Therefore…"
"Looking at the output file, it looks like many if not all of the messages a reading a payload that is 1 less than it should be.
55 02 3F 01 01 2A D3 D9. This is another error. It either has no checksum or no payload."
"Soren, I apologize for the earlier post. You're right, it should have length 4. I don't know what to tell you about the 3. I have been doing the same thing as you (custom Java decoder), and have never seen the same problem."
I plan to (eventually) build my own GCS. So far, I've created a simple COM port rerouter (for sharing a COM port across a network) for my GCS. I will have the APM on the drone (drone is connected to PC by local wifi network) and I will have my GCS on the PC. I think I have my COM port rerouter working, but I can't really test it because HK GCS does not allow me to connect to the virtual com port (unless the APM is plugged into it, but the APM is plugged into the drone not the PC).Whenever HK…See More
