That is what I was thinking when I asked the question. In terms of code size and speed, would it be possible on a PIC16 or PIC18 type chip? When using a wifi module the output is serial such as http://www.ebay.com/itm/serial-ttl-rs232-to-802-11-b-g-n-converter-Embedded= -WiFi-Module-with-antenna-/171018111917?pt=3DLH_DefaultDomain_0&hash=3Ditem= 27d1794bad, it was unclear what network layers were handled by the module and what woul= d have to be implemented in the PIC. It is something that I don't know much about, but wanted to find out if it was practical in theory before going farther down the road. Using HTML would allow access control with whatever he had on hand - computer, smartphone, tablet. What would be even more attractive for me (lower power and cost and size) would be to use a Bluetooth module such as http://www.ebay.com/itm/New-MIni-3-3V-wireless-Bluetooth-Transceiver-Master= -Module-Serial-Port-30ft-TTL-/261053250441?pt=3DLH_DefaultDomain_0&hash=3Di= tem3cc7fc7b89 but I don't see a method of sending/receiving data to client browser throug= h the bluetooth device without some programming on the client tablet. Is it possible? Gordon Williams --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
