How to detect that reconnect_retries has been exceeded?

[stefangotz]

When I set reconnect_retries to some value as documented in the README and I want my application to react to the fact that gmqtt has exceeded that number of retries and given up on reconnecting (e.g., to exit the application or to reconnect at a much later stage), how would I do that?

Hi @stefangotz
There is no special callback for the moment when client stops reconnecting
But the possible solution would be to check client.reconnect_retries property in on_disconnect callback

Hi @Lenka42 !
How would that work?
When I register an on_disconnect call-back function, it is called once when the client transitions from connected to disconnected. The gmqtt client then makes 4 attempts to reconnect and then stops without calling my on_disconnect callback again. So I'm still not sure how my application can be notified and react when gmqtt has given up reconnecting?

@stefangotz sorry, my bad. Please try upgrade to gmqtt==0.5.0 and check the following:

def on_disconnect(client, packet, exc=None):
    if client. failed_connections > client.reconnect_retries:
        # app.on_client_disconnected_absolutely() 

I checked, and in your in case with reconnect_retries=4 last time on_disconnect was called with client.failed_connections=5
Let me know, if it works now.

Hi @Lenka42 !

Thanks a lot for pointing that out! With v0.5, I do indeed no longer observe this issue. Resolved as far as I am concerned.
