FT EZ ID?

[LitterBug]

It would be easier to add it back in using the Custom Firmware Builder under the MSP section.

ArduPilot Custom Firmware Builder

ArduPilot Custom Firmware Builder. It allows to build custom ArduPilot firmware by selecting the wanted features.

custom.ardupilot.org

Good point. I was planning on setting up a full build environment for doing other testing. I will give this a test!

 

[LitterBug]

Hmmm. MSP GPS was already enabled......

 

[LitterBug]

Think I found it. GPS driver for Mavlink is not enabled.

I believe it will show that way to begin with. I'd try building it and load it and see if it shows up.

 

[LitterBug]

Hmmmm. Still not working. I think in the name of getting on with the test, I will just switch to the H743-Wing. I can resolve the issue with the F405 later.

 

[LitterBug]

Nuts.... not even working with my H743-wing. Not sure what is going on with my FT-EZID board. Works fine as RID, just serial connection does not appear to be working....

I see data from it using a FTDI adapter....

Can you put it back on the vehicle where it was when it was working?

That's the thing. I had it on the H743-wing as the last known working setup and it hasn't changed since then... Debugging....

Going to step away. I reset everything, put a standard GPS on, and it works with that. Just cannot get it to read the EZID.

I can tell it is sending 5 packets a second....

 

[LitterBug]

Took a left fork for testing and Flashed the H743-Wing to INAV 7.0.0 and FT EZID is recognized and works fine as a GPS with update rate of 5hz. This rules out a problems with wiring, baud rate, Serial port, etc....

So for some reason, it is just not being recognized by ArduPilot Plane 4.4.4.

 

[LitterBug]

Bingo.... Serial port set to MSP instead of GPS and it started working on the H743. >sigh< Back to testing on the F405.....

EDIT: DING DING DING! Same thing on the F405.... Now going to revert back to the "standard" firmware

 

[LitterBug]

>sigh< I updated my config notes above since that is what I was going off of for the serial port protocol.....

Reset F405-wing to "standard" firmware and it is still working.

It does repeatedly give an error message of GPS 1: Not healthy .... This will prevent arming.

 

[LitterBug]

Testing is going better with the F765-Wing. Actually able to arm and not getting the GPS 1: not healthy errors.

Now just need good weather later this week to fly it. Supposed to rain tomorrow.

 

[jonbrotherton]

Nice, and now you're back to exactly 1.0 HDOP

 

[LitterBug]

And it eventually got stuck in a different error scenario, Bad AHRS. Seems like it is fine just after boot, but after the GPS acquires a good number of satellites, odd things happen.

Yeah, I don't think HDoP is being calculated right.

I wish I had more input. I was able to fly my copter with it set up like you have yours, but it was scary. Lol

What I am seeing in the GPS/RID log data is very notchy positioning. Not really an issue for a high level view, but it would not be great for position hold. Almost like a rounding error.

 

[LitterBug]

Here's an example with data captured by OpenDroneID. Plot on the left is a more typical GPS plot from a different product, plot on the right is from the EZID. It would get it home in an emergency, but would be an unstable hover.

For Remote ID purposes that's close enough for me! 🤣

Have everything mapped out and bench tested on the F765-Wing. Ready to drop it in to the Surfer2000 and hit the field when the weather cooperates. Have "Manual" mode enabled as flight mode #1 in case there are issues with the nav features. Not setting up FPV for these tests. Do have Full telemetry back to the radio. Just need to check failsafe config. Done.

Rain and wind today. Would not be totally prohibitive to flying, but not the weather I like to "test" in.

Ready 2 fly. Everything checked...

 

[LitterBug]

Well.... It flew great in manual mode...

Stabilized.....That did not go well. Several errors on my part and I will see if the logs tell me anything. Error 1) not checking to see if stabilization modes were moving control surfaces in the correct direction. Error 2) Not flying several errors high when engaging stabilized mode. Really no chance to switch back to manual or recover. It went straight up.... and straight down.. . POP!!! Immediate battery disconnect then signal lost on impact, so unlikely it was a failsafe. The radio would have announced it before the POP!

Need to check the FC, FT EZID, and replace RX antenna then test it. Have some other options for "test" birds....
