Get disconnect reason codes from server

[ruicanas]

Hey!

I'm attempting to get the reason codes from server related with any disconnects. After a glance at the library I was not able to find a straightforward way to get them and I was wondering if this is implemented. Is there any work around to get them at the moment?

Thanks in advance.

I don't think there is a way to do this at the moment. I'll have a look to see if it is easy to incorporate.

Any updates regarding this topic? Or any hints on how I could achieve this?

Oh sorry I completely forgot about this. I'll see if I can do something this week

Hey, no problem! Just stumbled again on some weird disconnects and would be great to have the reason codes. Please, let me know if there's anything I can do on my side.

Hi, it looks like the library already returns disconnect reasons. Disconnect reasons are only available when running with the v5 protocol. v3.1.1 servers don't send DISCONNECT messages.

Currently it looks like DISCONNECT messages are only caught on invalid packets being sent. If an invalid packet is sent you'll get a MQTTError.serverDisconnection thrown, you can get the reason from the error's associated value.
