NRF9160 AWS FOTA fails to load binary

Gabe

We have worked through getting AWS MQTT working and have the FOTA job file loading properly. When the HTTP request is made the file begins downloading but fails to download after a seemingly random period of time. Anywhere between 3-30% complete. The failure happens when the receiving bytes step takes a considerable amount of time and then the next http request fails. The FOTA library then resets and tries to download the file again with the same result.

    Our RSSI is around 50. The RSSI is not why it works with a different provider. The problem is in the libraries ability to handle delayed or missing packets.

    No fix yet as far as I know. I believe it is being worked on at the moment.
