Firmware v1.15 stable _ GPS not detected _ CUBE orange _ Herelink

Radio telemetry Herelink

Hi,
Today I installed the Px4 v1.15 stable release thro QGC v4.4. It looks like GPS is not detected neither thro GPS1 primary nor GPS2 secondary but the quadcopter take off well with my pre tuned PID values created under Px4 v13.3 parameter back up .
So i had to return back to my previous firmware v1.13.3 and the GPS detected immediately.
i also saw that some GPS parameters from v1.13.3 are not present in v1.15 stable.
Anyone with a similar issue or solution …

thank you

Having the same issue here but with a PixRacer Pro instead. After flashing to v1.15.0, GPS does not show up in QGC main page and there is no GPS_RAW_INT message present in MAVLink Inspector. After downgrading to v1.14.4, GPS shows up and GPS_RAW_INT message is present

Weirdly enough, when I tried with a Pixhawk 4 on both v1.14.4 and v1.15.0, the same GPS module shows up and has GPS_RAW_INT message present. I just submitted a bug report on the px4 github

Hi
Great info. Did you compile the specific board or used the precompiled board from Github.

I tried both ways and same result. Actually, I just had a response on the bug report I posted on GitHub ([Bug] GPS does not show up for PixRacer Pro in v1.15.0 · Issue #23714 · PX4/PX4-Autopilot · GitHub) although I haven’t tested it yet. Maybe it’s what you’re looking for too

Thanks. That is one good direction to check out. What is sepentrio !!

I just got to test it and disabled SEP_PORT1_CFG as advised. That worked for me! Hopefully that works out for you too!

Hi,
I also see that on Mavlink console v1.15 GPS rate reading is now showing 0 b/s . Earlier on v13.3 it used to show 600b/s or something close. On QGC i see the coordinates !!

This PR might have fixed it? Can you try again?

GPS1 is assigned by default to add more context. This is unintended in v1.15, so we will be publishing a v1.15.1 release with a fix. Meanwhile, please disable SEP_PORT1_CFG as advised above.

Hi,

Disabling SEP_PORT1_CFG does solve the issue. GPS 1 and GPS 2 is recognized and i do see the coordinates but the rate reading is not published in mavlink console. But in QGC( v4.4) , I do see the coordinates. I used to see the rate reading in v13.3

Can you please share a log with this problem? make sure SEP_PORT1_CFG is disabled, and your GPS is connected to GPS1

Additionally, and likely unrelated, but since you are upgrading from v1.13, I want to point out that v1.14 introduced breaking changes that are also valid for v1.15, please make sure you read the upgrade instructions for v1.14
