I know, this question was asked almost one year ago, but I assume I have the same problem right now. My problem is showing up as follows:
- Suddenly, my disconnect Callback is called
- I try to reconnect immediately (not in the callback but in a Thread that is informed about the disconnect)
- Connecting is successful
- Subscribe to topic is also successful
- disconnect callback is called again, and guess what happens?
Finally I could reproduce the behavior by disconnecting ethernet. While debugging, I found out that there is a variable "nxd_mqtt_ping_not_responded" on the mqtt instance. This variable was set to 1 and never reset when this happened. By looking into the (protected) code I realized, that this might be the problem. So I simply tried the following: Before reconnecting, I set the variable "g_mqtt_client0.nxd_mqtt_ping_not_responded" to zero. And now it was able to reconnect!
Could you test if this is also helping you?
Best, Pi Is there anybody from Renesas who could help here? Is this a known bug? Is my workaround feasible?
Thanks!
