Matt,

I have modules with me for replacement, if necessary.

I am concerned about your comments regarding soldering. All the v2 modules are supposed to be machine soldered, and we have had almost zero returns of broken modules.I would be grateful if you could let me know the serial number of your module, the approximate date you received it, and if possible a picture of the soldering issues.

I too am perplexed why the module would work SMS but not GPRS. Perhaps you can try setting the vehicle type to 'XX', which would eliminate any can bus/message issues, and see if the problem still occurs.

Please eMail me, off list, as mark (at) openvehicles (dot) com, and I'll work through this with you.

Regards, Mark.
