BN-220 GPS module is not working on my F411-WING board. Please help!

Current Behavior

Hi all, it's my first time building my FPV plane running iNAV but I encountered a stubborn GPS problem.

So my BN-220 GPS is connected to the UART2 ports on the F411 WING. in INAV 2.6.1, I set the UART2 ports for GPS.
When I power the board on, it doesn't detect anything from the GPS. The GPS Icon in iNAV is red and the GPS module itself
doesn't flash at all.

I have connected it properly and nothing is wrong with the wires and the RX/TX wires are swapped of course.
(When I put the same GPS with it's wires on a ZOHD Kopilot, it does flash. But when I plug it back in the 411, it doesn't.

Of course, I enabled GPS in INAV and in the configuration tab, I've tried the NMEA, UBLOX & UBLOX7 protocols but they don't work at all to flighten up the GPS.

What is the problem? What can I do to get my GPS working in iNAV so that I see a blue icon and a blue flashing
light on the GPS itself?

I assume you're powering from the flight battery not just the USB connection ?

• Yes. I tried it with and without flight battery onboard.

Can you post the Ports tab and wiring?

Check the "GPS" tab, especially, the update rate. With UBLOX it should be 5hz. If it's 0, it's probably a wiring issue (try swapping RX & TX wires then). Also post the ports tab, as fikusir asked for.

Also BN220 should use UBLOX7 protocol, not UBLOX, so you will get a update rate of 10hz instead of 5hz.
