Certificate error when building Qt5 app locally. #40

Closed vjacob closed 1 year ago

Hi all,

I'm trying to build the provided stream-qt5-test example on my local machine (Ubuntu 22.04) running a local instance of Astarte 1.0.4. I followed the 5 minutes guide and all is running well since the docker image of the Qt5 stream application runs OK and can post values to Astarte. When I build the Qt5 application locally using Qt 5.15.3, I get an SSL error on the Mosquitto transport connection (see below). This is after pairing a new device, which seems to run well. I can also see the device in the dashboard, where it says 'Never connected'. When I remove the IGNORE_SSL_ERRORS=true flag on the docker image, that image also fails to connect. So I'm pretty sure I need to somehow turn off client certificate validation or at least ignore errors on my build. However, I have no idea how to proceed as such.

It is to be noted I also built the SDK myself. Maybe a certain build setting needs to be used?

Thanks for any pointers.

After a lot of digging, I found that one can set a flag in the device configuration file (in the astarte-device-xxx-conf folder) 'ignoreSslErrors' which can then be set to true. From that point on, I got a valid connection where my locally built Qt5 app was successfully producing values for Astarte.
