[Ovmsdev] 1.3.1

Dear all

In the last 2 days my digital speedo seems to reset itself for a reason I don’t understand.

The OVMS has always been under power and is sending data. 

It seemed to happen after I parked my car in a garage where the GPS signal can’t be received. 

I tried to reproduce the problem but couldn’t do it.

It happened the first time after firmware update to 1.3.5/V1 experimental. 

I could re-activate the feature via application without any problems.


Question: does anyone of you has the same problem?

I think it was a series of four fairly fast green led blinks, red led off, that repeated maybe 5 or 6 times and ending with a solid red and green.  Then the entire sequence would repeat.  OVMS was down about 7 hours total with the last hour or two being in good cell coverage area before I did the hard reset.

Do you remember what code the lights were flashing?


I checked mine, and it was bizarre. Green LED was flashing 1 (GPRS up and connected), and red LED was off (no errors found). But, when I connected a PC to the DIAG port (thanks to v2 hardware I can do this now when the box is running), the modem responded just fine but there was no comms between the modem and the PIC. As the LEDs were flashing, the PIC was definitely running. It seems that the RS232 port was just dead on the PIC side. A hardware reset brought it back alive.


I guess I'll have to add a timer to the NET driver code for data last received on the modem port. If nothing is received in a few minutes, then time to reset everything.


Regards, Mark.

Strange, mine did the same (at roughly the same time). Mine still hasn't recovered, but is in good coverage area now.


Without resetting, I'm going to put a serial console on it when I get home tonight. Hopefully I can see what is going on then.


Regards, Mark.

I lost connectivity today with the car in our garage.  We live in a poor cell coverage area and this is not that unusual.  However, later today I drove into the city where coverage is excellent and OVMS did not reconnect.  After hard reset OVMS was able to connect.  If there is any other information I can supply, please let me know.  I updated firmware to 1.3.5 a couple days ago.

1.	If the car is in an area of poor / no cellular coverage, then drives out to an area of good coverage, does OVMS connection re-establish? In particular, if you previously saw a situation where you had to unplug-then-plugin the module to hard-reset it, does that still happen? If realise that this will take longer to know, as it was very rare.
