Hi Mark,<br>
<br>
Looks like that did it. No more disconnects. Yea! The verbose
logging is good now, too.<br>
<br>
Greg<br>
<br>
p.s. Just curious, why does Git think I'm still one commit ahead of
Master?<br>

I think the issue is the last empty ‘send’.

<div class="">Really not sure why it is working for me, and not

Bingo! Well, mostly. Changes made fixed the corruption
on both Parameter and Feature list fetching, both of
which now complete back to the Android app. Changes
pushed to my github fork.<br class="">
<br class="">
But there's still a disconnect. This one looks like a
buffer size limit being hit, given that the log ends
mid-string. I tried setting the log level to 'warn',
and the disconnect still occurs, so it's not due to the
large text output. Or, is the disconnect intended after
these fetches, and the message truncation just a
consequence of our log buffering system? The server
reconnects automatically, after a short delay.<br

Hi Mark,<br class="">
<br class="">
Memory was my first thought too, but there's
no overt indication of that. There's just
an apparently spontaneous close, except it
always happens at exactly the same place.
This is with the module sitting on my desk
(not in the vehicle). It acts the same in
the car, but with real data. Tapping
"Features" on the V2 client is similar.
This is with the module connected to the
local network via wifi. <br class="">
<br class="">
I tried taking out SSH Server and SD support
from the build config, to save RAM, but no
change to the results. No change with a
fresh fetch of Master from Github just now,
either. Any idea what I can change
(menuconfig, module config, logging), to
reveal more info?<br class="">

<div class="">I think this is a different
issue. I used to have this all the time,
