Want a simple one page server app that can receive data from one GPRS connected device.
Device communicates via TCP/IP with Modbus over TCP (Open AT command set ex Wavecom ).
The app should do the following :
a.) Accept connection from the remote device.
b.) Query & display Phone No & IMEI.
c.) Query & display device 4 logged data values with refresh rates as in (d).
d.) User select-able refresh rates by way of radio button -as 10s,1min,5,15,30min.
e.) Accept a heartbeat message, and display a green led on webpage. If the heartbeat does not appear for more than 5 mins after the last query, then turn led color to RED (means device offline).
-Command documentation provided.
-Solution should be highly scale-able (>1M connections).
In your bid briefly mention your proposed architecture and server technology.
