Analysis
We've confirmed through Wireshark that the http server hosting our file is not the cause of the problem. Please see the last line in the below Wireshark screenshot. This shows the absence of TexasIns_8b:9b:51 response. This coincides exactly to where the download stops prematurely.

Questions/Request
Can you provide an AT command with a specific example, in C, of how we can determine what is causing our download to halt abruptly? Otherwise, what do you recommend?
