    Hi Mark,<br class="">

    Looks like that did it.  No more disconnects.  Yea!  The verbose

                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 class="">

                            Memory was my first thought too, but there's

                            an apparently spontaneous close, except it

                            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="">

 be correlated to this: sockets don't get closed when losing the
 connection. The effect is visible on both web and telnet server (ssh
 not tested). To reproduce, switch the Wifi network with an open
 connection, the port will not be available until timeout.
