[Ovmsdev] some partial success

Thanks Mark,
Looking at the code the VEHICLE TYPE is the 4th parameter of the MODULE command.
I will test this today and report back.
I was looking at the user guide for Tesla and the MODULE command has listed 3 parameters...
I forgot to mention that I tested 2 different sim cards in Sweden:
1- mini sim format (like iphone 4) with adapter, operator 3 - did not work, the error code is blinking too fast for me to reliably count it.
2 - standard sim format, operator telia - worked for sms
Still haven't tested the gprs function. Any good advice on how to test the GPRS function - can I setup a simple server to just register the incoming messages?
Nikolay

Nikolay,
Unfortunately it did not seem to work. On STAT request the response was generated from the net_sms code and not my new code for the Think EV.
So long as you've registered the hook correctly, it should work. Are you sure you set the module correctly to TC so your vehicle module is the one actually used? This is the SMS MODULE command (I think it is the last parameter).
You can SMS PARAMS? or MODULE? to see what parameters are set.
Also - what are the capabilities used for?
>What does "C6,C200-207" mean? I get the 200 to 207 are the extra commands but how are they plugged to the rest of the code?
This is a new v2.x thing, used to tell the App what the capabilities of the vehicle module are. We don't use it at the moment, but plan to use this in the app code in order to customise the functions and appearance on a per-vehicle-module basis. For example, if the vehicle module is able to support a lock/unlock command, the capabilities will tell the Apps that, and the apps can update the UI appropriately.
f I reprogram the board, do I need to restart it somehow? Or is it enough to just reprogram it from the mplab x and the board will restart?
The board will restart automatically after being programmed by MPLAB-X. If you want to restart it, you can also SMS RESET or just pull the power.
Regards, Mark.

took, I found out CIPSEND will fail with a plain "ERROR" if the
data size exceeds about 1500 bytes. I guess that's either the
SIM908 buffer size or the max network packet size. I thought the
SIM908 would handle dividing data into packets as needed. The
SIM908 manual mentions the max packet size depends on network
status and should be queried by "AT+CIPSEND?". After the overrun
net_state_activity() will not recognize "ERROR" to terminate the
pending msg, so will run into the timeout and start a network
re-init.

data packets into multiple CIPSENDs. Would be nice if the net
functions take care of this transparently.

>>A secondary issue turned up from the diag log: the SIM908 crashed
in the middle of a CIPSEND command while the module continued to
run normally. The module still thought it's in NET_STATE_READY, so
did not re-initalize the modem. The connection could then be
established on the next CIPSTART, but the complete INIT stuff had
not been done. So it seems independant SIM908 resets need to be
handled as well, and they can occur anytime. I'll see if I can
solve that too.

I introduced a GPS logging to optimize my antenna positions and managed to get some really nice tracks three days ago, so I don't think this is related to my changes... but I'm not 100% sure. I tried different antenna positions and another GSM network, but the connection keeps dropping when moving the car, and GPS position updates need minutes. Could be weather conditions ...or some tricky race condition bug?
