Hello,
I'm still here... you, and I discussed this at length last night, and as I mentioned I have a recommendation from a customer for a device that they use for the same purpose
Keep in mid the device uses GSM & GPRS technologies to communicate with the server, shortening and packing the numeric, and binary data into single bytes to conserve power.
I've reduced my bid to a realistic amount, and am willing to work with you on setting up OpenGTS as a server side solution to track roll off dumpsters
Please contact me on the Freelancer board so we can continue our conversation
Regards,
John H. Ward, Jr.
