ambigous documentation on aws iot topic subscriptions

[livetsMozell]

hello, just want to notify you about this part of documentation, https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/libraries/networking/aws_iot.html#subscribing-to-non-aws-specific-topics

The code snippet is not according to the description above. The description states that you should subscribe first, then init, but in the code you subscribe after init. 

kind regards

ive had some issues with the time it takes before custom topics I have subscribed to starts reaching devices.. they can post to aws, but they are not receiving. Sometimes they devices are reachable through their subscribed topics instantly other times they are not reachable until the next day. I dont have any rules that should interfere with subscriptions.

Hi,

The default AWS IoT example code sets the connection to persistent by default. As such, changes to the subscribe topic in the firmware are not reflected when the device next connects. 

As such, the following setting should fix the issue.

CONFIG_MQTT_CLEAN_SESSION=y
