Heres my problem, ive got a few ethernet boards connected in different locations, all they do is send a get command to a server. I need to be able to configuer them all remotly, so that i can change the server that they connect too and the get data they print once connected. The best way i can think to do this would be via MYSQL, after searching for ages i found lots of tutorials on how to add data to a DB but none on how to query? So i think if each device had an ID number that was in a field in the DB to query then possibly i could then get the data back to it. Most of the tutorials suggested using PHP to work between the two when updating the DB is it possibe to do the same with a query?
Or mabe theres a really simple way of doing this and im missing it?
Thanks for your time!
