[Ovmsdev] High hologram usage

[Michael Balzer]

Craig,

I cannot see how the modem in your bench module "dev" could cause >8 MB 
network traffic when the module has Wifi all the time, except by many 
reconnects + Hologram counting these as traffic (which I think they 
shouldn't and don't do), or by the module not using Wifi due to a test 
or very poor signal level.

The only modem change coming to my mind is the GSM signal quality 
extension by Jaime, which initially had switched good & bad signal 
levels. But that wouldn't have triggered a modem reconnect, rather 
reboots, and that wouldn't have gone unnoticed by you.

You can check the cellular reconnect count from "cellular status debug". 
Of course that only counts reconnects that need an IP renegotiation, not 
transparent transitions to other cell towers.

Looking forward to your findings.

Regards,
Michael
