[Ovmsdev] Initial OTA update

Thu Apr 19 12:29:54 HKT 2018

Mark, 

The vehicle id is TRS0879 and I tried to do the remote charge multiple
times today beginning at ~12:40p PDT through to ~4:30p PDT [using the
cellular modem].  This evening, beginning ~9:15p PDT, I've tried to
start a charge remotely over Wifi.  So far for all attempts, no joy. 
I've tried using both the Mobile app [iPhone], as well as the web app
contained in the v3.  All tries appear to timeout without starting the
charge. 

I'm wondering if the "Timed Charge" status of the car, is overriding the
request to "Start Charge" [immediately]. 

Thanks for your kind help with this. 

Chip

On the app screen that charge "slider" slides over to the right, but just stays there and ultimately times out.

Hi Michael,

Interesting...  I was going to write back and say that the 3.003 to
3.004 update went very smoothly, with no queue overflows being reported,
and that all was well.  I don't recall if the modem was connected at the
time, however.

A side note for anyone having trouble connecting to AP mode with their
cell phone...  I've always had a lot of trouble with timeouts and such,
and finally tracked it down to a similar issue as above.  If the phone
has both an LTE and AP connection, the http request to 192.168.4.1 often
goes out over the LTE path, and is therefore doomed.  Disabling LTE
"fixes" that, but of course, also disables your phone.(or at least the
data part).  I haven't found a good way to beat some (routing) sense
into the phone otherwise.

This was with my new Google Pixel2, so it's not a matter of an old buggy
device.  (Ok, so it's a new buggy device...)

Also, the first time you connect to the AP, the phone _blocks_ all
communications with it until you answer the annoying notification
(usually hidden in the background) that says "Hey, we can't get to the
Internet with that AP.  Are you sure you want to stay connected to it?",
or words to that effect.  Me thinks they have taken this always
connected Internet meme a bit too far.

Greg
