Examining Mobile Hotspots - Orbic Speed RC400L - Part 3

by ogmini

Still looking at the Orbic Speed RC400L hotspot. You can find all the previous posts at https://ogmini.github.io/tags.html#Mobile-Hotspot. Today, I started looking at the various log files located at /data/logs.

There are 5 log files:

Log File Notes
atfwd Possibly logs AT commands?
cpe Possibly logging data usage?
fota Checking for upgrade? Maybe Firmware OTA?
kn General log file? I see entries for dnsmasq-dhcp, hostapd, and kernel stuff
oma ??

There is a lot to unpack here and it is delving into cellular technology of which I don’t know too much about. Good example are those AT commands. I have a lot of research and reading ahead of me.
