Hello, I am trying to set up GPS on my drone and it doesn't seem to be working. The reason I think it's not working is the GPS icon/symbol won't turn yellow in Betaflight, it's always grey. I did connect a battery to the drone and then see if the GPS icon would turn yellow - it did not. It's my first time working with a GPS unit so I'm sure there could be something I'm missing. I've read through a number of other posts but haven't found anything to solve my issue so I'm making my own post. Maybe I just haven't gotten to a step later in the GPS set up process that I need to do? I appreciate any help!

My understanding is that the GPS icon at the top of Betaflight should turn yellow when GPS is correctly wired/configured and you connect a battery to the drone, and that it doesn't need to see any satellites for the icon to turn yellow. Is that true? Is that a good test to see if GPS is set up correctly?

I connected the GPS RX/TX to UART4 on the FC per iFlights wiring diagram, as well as 5V and ground. Link to iFlight's wiring diagram: https://shop.iflight-rc.com/image/catalo...200923.png

With the wiring connected as shown in my attached photos, the blue "TX" LED blinks on the GPS. When I brought my drone out of my basement and near a window, the red "PPS" led blinked as well. 

In Betaflight ports window I set up UART4 Sensor Input to GPS and chose 9600, and in the configuration window I turned GPS on and chose UBLOX protocol and turned on Auto Baud and Auto Config. This is what iFlight recommends in their wiring diagram linked above. The GPS Icon always stayed grey. Then I tried all of the baud rate values (or whatever they're called - the 9600/57600 etc. numbers. I tried auto as well, it went to 57600), and I tried all the baud rate values again with NMEA protocol. GPS icon stayed grey. 

Then I swapped the RX and TX wires on the FC to check if I wired it backwards. When I did this, the blue TX LED no longer illuminated on the GPS unit so I swapped it back to the way I initially had them, which is how it's shown in the attached images. After swapping back, the blue TX and Red PPS LEDs blink again.

I attached 3 screenshots of the Betaflights screens: Ports, Configuration (GPS section), and GPS.
I also attached 3 images of the wiring of the GPS to my FC.

I know you said you tried swapping over the wires but your current photos show them incorrect. The white wire (TX on the BN-880) needs to be wired to the R4 pad and the green wire (RX on the BN-880) needs to be wired to the T4 pad. After doing that, use a multimeter in continuity (beep) mode to check that you have no short circuit between ant two of the R4, T4, 5V and GND pads.

The GPS icon in Betaflight Configurator will illuminate yellow when Betaflight detects a data connection with the GPS module on the configured port. It doesn't need to have a 3D fix for that icon to illuminate.

If you still get no luck then try setting the Auto Baud setting to OFF and the baud rate for UART4 to 57600. Failing that, try a different UART.

You can also try running the 'gpspassthrough' command in the CLI. That will let you see if there is any data communication going on between the FC and GPS module. It will just be a load of binary data hieroglyphic characters but at least it will let you see if the FC and GPS module are trying to talk to each other.

Now that you say that, I see I do have the RX/TX wires incorrect in the photos. I will swap them and try again. Thank you!

Great info, thank you!

Okay, thanks!

I swapped the GPS RX/TX wires per your comment and the GPS icon turned yellow in Betaflight. I must have had some other issue as well the first time I tried the wires that way. Thank you!

I have another question that I wonder if you or someone knows about. The BN-880 GPS comes with a compass and has two extra wires for it, SDA and SCL. I don't really plan to use this feature and was wondering if it would be fine if I don't connect those wires and trim them off near the GPS unit. Hindsight 20/20 I would have ordered a GPS like the BN-220 which doesn't have the compass, but I didn't know that at the time. I'm pretty sure this will be fine but thought I'd ask.

Cheers!

Yes, no need to connect the SCL and SDA wires if you're not using them. Betaflight only uses compass data on the OSD anyway, so you're not really losing anything without them.

That's great news that it's now working

I would just "de-pin" the wires from the plug rather than physically cutting them back. Then if you ever decide to make use of the compass you can just put the wires back into the plug again.

Until recently I was also under the same impression but have since discovered that Betaflight does actually use a compass (if one is configured) to help aid with more accurate GPS Rescue. Without trawling through source code I'm not exactly sure how it gets used, but it's mentioned in the Betaflight documentation.

There is also a specific setting in the CLI called "gps_rescue_use_mag" that allows you to enable or disable that particular feature.

True. That specific setting was added (and the default set to "off") per this discussion here, where the author argued that having a mag does more harm than good if you're not absolutely sure it is calibrated properly. 

https://github.com/betaflight/betaflight/pull/7294

Betaflight does not have the same level of sensor fusion/Kalman filter as something like Ardupilot, so if your compass is not properly calibrated and/or experiences interference (which is very common on a small quad), and GPS and mag heading disagree, it will cause a Flyaway/sanity check error and the quad will just disarm. In a RTH situation, you probably don't care which direction the quad is facing as long as it keeps moving towards you until you can regain control.

The default setting of "gps_rescue_use_mag" appears to be ON according to it's current setting on my quads and a CLI diff not listing it as a changed value. The setting mentioned in that PR is "gps_rescue_no_mag" which is the reverse of the current setting, so the devs probably just renamed it to be a non-inverse setting name to avoid any confusion.

I don't have the compass wires hooked up on mine anyway so even with that setting ON it won't do anything and I have no intention of running or using a compass on my freestyle quads so I have no way (or appetite) to find out how good / dangerous that setting is. If the default value is ON then there must be some level of confidence that it works. Someone else can test it though and see if they get their quad back or not

ahahaha 

Like Snow, I don't use the compass feature of the Matek M8Q-5883 GPS units that am running.
Also, I just "de-pin" them from the connector as that is the cleanest way.

I ended up depinning the wires instead of cutting them, only took a couple extra minutes. Thanks for the suggestion

I'm seeing some inconsistent behavior out of the GPS and I'm wondering if anyone has some experience or feedback regarding it.

Basically, when I power up the drone/GPS either by connecting the FC to my laptop which (powers the GPS as well) or by plugging a battery into the quad, I see different behaviors:

1) GPS seems to start correctly. Meaning the blinking blue LED (labeled TX) comes on, blinks slower for a second or two, then rapidly for a few seconds, then starts a steady blinking rate that continues until I power it off. GPS icon turns yellow in Betaflight and I actually got a 3D fix once!!
2) no blue LED comes on. Red LED (labeled PPS) blinks very faintly for a bit then stops altogether. GPS icon stays grey in Betaflight
3) Red LED is steady ON at normal (bright) intensity. GPS icon is grey in Betaflight
4) No LEDs come on at all, GPS icon is grey in Betaflight

Option 1 is the most rare occurrence at this point. Option 4 is the most common. I kind of suspect if I left it powered off for a few hours or more I might see option 1, 2, or 3 instead of 4, and then it would revert to option 4. This is because I was at option 4 last night and gave up. When I came back to it this morning I saw Option 2 then 1 (got 3D fix) then 2 then 3 then 4. It's stuck at option 4 now...

I tried unplugging and re-plugging the connector into the GPS unit, no change. I haven't done anything with the wires that are soldered to the FC since it was working, drone has been put back together so they're relatively protected. They were probably tugged on while reassembling the drone, but after reassembling the drone I got option 1 probably at least 6 times before starting to see the failed conditions (2, 3, & 4).

The GPS unit has gotten knocked about a bit. I had it balancing on top of my GoPro on top of my drone and it fell off a few times, falling ~5 inches and hitting the table. Are these units so sensitive that this knocking about could damage it? It does feel fragile to me.

I appreciate any feedback/ experience ya'll may have with this. I ordered two BN-220s and I'll probably swap out the BN-880 because my suspicion is I damaged BN-880 while installing, troubleshooting, and playing with it.

Cheers,
Mike

Hi Mike,

Before I started using a GPS, I did a bit of research and asked for advice on this forum and
here is what I came away with.

Beitian GPS units are FRAGILE and tend to break during a crash. KaityLynn used Beitian, but
they were breaking all the time so she switched to Matek GPS units which don't seem to be
as fragile. Other long range pilots also recommended the Matek units, but no one recommended
the Beitian brand. 

So based on the information that I had gathered, I pretty much only buy Matek GPS units because
I want them to work and not break all the time. I personally use the Matek M8Q-5883 almost
exclusively. I view a GPS unit like a fire extinguisher...If it doesn't work, it is not worth the money.
Well, I want mine to work. Yes, they cost more, but sometimes you get what you pay for. So far,
I haven't had any issues with my Matek GPS units; they just seem to work all the time. 

As for Beitian...well, I really can't say, but "heard" that they are fragile and break a lot.  

Thanks for sharing your research iFly4rotors. I looked up the Matek M8Q-5883 and it looks like a much more polished GPS than the Beitian. Seems worth ~twice the price. I agree with your analogy. Some amount of peace of mind can be bought.

I have found the Flywoo mini GPS (available with or without compass) to be pretty comparable to the Matek M8Q-5883, but they are lighter and less expensive. They use a uBlox receiver that is much higher quality than the Betian units.
