The TCP server on your phone will only be accessible when the phone is connected via WiFi.
When connected via the cell network the IP address will not be available to connect to.
If you had the Photon run the TCP server your phone would be able to connect to it as long you also setup some port forwarding on your WiFi router.
am only interested to make it thru the wifi.
The photon will be in the house and I don’t need to hear it when I am outside the house. So I don’t need to make it work with 4G
Can I get some tips or tutorial? Like how to setup a server for the phone? I guess it must some kind of socket programming?
