GET request to multiple server / Master to slaves
Posted: Thu Feb 20, 2020 3:28 amHello everyone,
\* I am new on this forum so I hope I can post it here
/* sorry for my bad English
I try to establish a link between one ESP8266 master and several ESP8266 slaves (max 5)
I succeed to control one esp by an other one using a request GET from my master (client) to the slave ( server)
But I can’t establish connexion to multiple server from my master.
My master create an access point,
Connect to the first server
Send a GET request
Close the connexion
But can t connect to the server2
However, I can send request to all different server from my phone.
Here the piece of code I use for the master part. (Slaves side works fine)
Is it possible to do it by several GET request or do I to built a MQQT broker or .... ?
Thank you very much for your advices.
