AWS_IOT aws_iot_connect, error: -119

Hi,

I have an nRF9160 and working am off of the AWS_IOT sample code. When I start the device, the error messages occur 2-3 times and then the device connects successfully with the message "AWS_IOT_EVT_CONNECTED".

Error messages:

connection_poll_start failed, error: -119

aws_iot_connect, error: -119

What does error -119 mean?

Why does this occur a few times before a successful connection event happens?

Thanks,

Alvin

What does error -119 mean?

It looks like the error just means that the connection poll thread is running and that the connection cannot be polled one more time. This doesn't seem like such a big deal to me, but maybe I'm wrong. You can try disabling the poll thread with CONFIG_AWS_IOT_CONNECTION_POLL_THREAD=n.

Hi Hakon,

I'm using NCS v1.9.1 and mfw 1.3.1

Thanks for your answer below, it looks like this error started happening when I changed the next scheduled time for the next connect_work_fn() call from 30 seconds to 5 seconds. It stops happening when I change it back to 30 seconds.

Is there a minimum time required between aws_iot_connect() calls?

Not that I'm aware of. I assume it depends on the time it takes for the TLS connection to complete.
