Communicating between two different applciations

[Alberto Perri]

Dear Erlang friends

I have two applications I downloaded from git_hub. One is influx_udp and 
the other Erlang-influxdb. Is there a way i can communicate with these 
two different applications with a gen_server process? I've called the 
processes demo.erl.

Essentially using demo.erl i would like to query an influx database 
using using the Erlang_influxdb, format the queried result in demo.erl 
and then send it from there to a database using Influx_udp.

Best regards,
Alberto
