#1 GPRS mobile modem
Posted: Thu Dec 20, 2018 3:22 pm
and now for something completely different
I' m thinking this will/may be for Nick or Nick but others may have an angle.....
I currently upload data from a remote AVR processor to a web server that processes weather data...all is good!
I've just implemented a database on my server and some php scripts to maintain a db....all is good!
well, all is good if I message the php script through a browser address line..the database updates or lists contents ok....
if I message the php script via tcp GET using the GPRS modem my webserver doesn't acknowledge receiving any messages. The GPRS unit responds to all my modem commands and connects(or says it does) to my web server and responds ok to messages sent...but the web server doesn't receive the messages(or at least the messages dont appear in my visitors or error log. I use exactly the same method and commands for the uplink that currently works.
anybody any experience in this area?
web server support will only commit themselves as far as to say they MIGHT be blocking the IP address I'm using and I should try white listing it. Problem there is the address is dynamically allocated everytime I fire up the modem, which could be frequently as I reboot every time I get a comms time-out. Webserver support say nobody else is using this method of comms, which I find difficult to accept.
I'm in the process of moving between scratching my head and tearing my hair out.......
