Parameters - setParamFloat works but setParamInt does not

MAVSDK-Swift is on mavsdk-server 1.4.2: https://github.com/mavlink/MAVSDK-Swift/blob/main/Package.swift#L50. Let me try to update that to 1.4.4 tomorrow 👍

Right, so there have been a couple of fixes since:
mavlink/MAVSDK#1703
mavlink/MAVSDK#1788

You can see the changes here: https://github.com/mavlink/MAVSDK/releases

[mmanionRIIS]

I installed MAVSDK on MacOS using Homebrew, following this: https://mavsdk.mavlink.io/main/en/cpp/quickstart.html

Will give building form main a shot.

What param are you setting? What autopilot (I assume PX4?), and what version of it?

[mmanionRIIS]

I'm using ArduPilot. I'm unable to change the RTL_LOIT_TIME or RTL_ALT.

I also tried the PILOT_ACCEL_Z, TERRAIN_SPACING, and STAT_RUNTIME as well, all unsuccessfully.

Edit: I also accounted for "increments", example. RTL_LOIT_TIME has increments of "1000".

What version of mavsdk_server or MAVSDK-Swift is it using? There have been some fixes, and for ArduPilot there might be some more coming up with MAVSDK v2.0.

[mmanionRIIS]

I've updated to the latest version of the MAVSDK-Swift on the Main Branch, so 1.1, looks like it was updated 2 months ago.

Drone Specs:

Could you try with the newly-published MAVSDK-Swift v1.1.1?

[mmanionRIIS]

I updated to 1.1.1. Unfortunately, had the same result.

Any chance you could try to debug what's happening in C++? Two ways:

1. Build MAVSDK-C++ and try it there from your laptop (I guess it's a problem related to Ardupilot, not iOS).
2. Build MAVSDK-C++ with mavsdk_server, run mavsdk_server on your laptop, and connect your iOS app to it using this interface.

I would personally go for 1, build a small example (e.g. this one) and try to reproduce there 👍.

Also maybe @ykhedar has an opinion 😇.

[mmanionRIIS]

Thank you, will try this tomorrow and let you know how it goes!

[mmanionRIIS]

Still working on resolving some errors I'm getting when building the C++. I'd bet this is on my end and will let you know when I get the C++ app up and running.

I'm pretty sure my error is related to mavlink/MAVSDK#1875

Seems like you are trying to build an example from main with a MAVSDK from 1.4.x. How did you install MAVSDK? You should build it from main 👍
