Send device sensor data to external http server

[matc1]

Have you tried the “Remote Access” (REST interface) feature in phyphox, so connecting to an internal webserver on your mobile? We are aware of school networks that do not allow device to device connections. That's the only possible reason I can think of off the top of my head...

Where i can find docu about  (REST interface) ? 

My scope is to send data outside mobile without any polling, versus external server.

Ok thank's i will try at home network.
