Trying to work out ways to provision OVMS modules without SMS.
One way is the new DIAG port SETUP mode. But, that requires a RS232 connection to the PC (not so easy nowadays, with a USB-RS232 adaptor required for most laptops). Also kind of messy for v1 modules.
The main reason I'm thinking about this is for the globalsimcard provider I'm working with. They can provide SIM cards that work globally for data only, with pretty good rates. Cards are good for 12 month validating and can be renewed for another year for less than US$10. Monthly cost should be US$1 + data, hassle free, and data should be less than US$2 for most providers. If we can auto- provision these, then setup should be to configure the provisioning information as you want, on the server, then just plug the SIM in and go.
Every SIM card issued has a defined prefix in its ID. I'm trying to find out of the globalsimcard prefix will always be the same, and will always differentiate these from others. If so, then we can auto-provision based on SIM ID as well (without even needing the OVMS-AUTO phonebook entry).
What do people think? How easy would it be for people nowadays to create a phonebook entry on a SIM card?
This is the first feature I thought of after ordering my v2 OVMS. SMS is so expensive on my regular cell phone that it seems prudent to find a way to avoid it altogether on the OVMS. Your mention that a provider offers a data-only plan fits right into my line of thinking. I have not even started yet, but I had planned on looking at the firmware source to see about ways to perhaps compile in these provisioning values. I realize that I am probably one of only a few customers who could deal with compiling and loading firmware, so my potential solution is certainly not a universal solution. I also have access to USB serial solutions, so I'd be interested in non-SMS provisioning solutions that require RS-232. As for SIM card editing, I was planning on recycling the SIM card from my RAZR v3. Assuming it will still power up, I anticipate that I could make the required entries and move the SIM card to the OVMS. Brian Willoughby Sound Consulting
