Connect two ESPs, one as Server/AP the other as Client
Posted: Sun Sep 18, 2016 12:32 pmHey guys!
I'm about to connect two ESPs with each other but the one acting as a Client is not able to connect to the SERVER being run on the Server/AP ESP. The weird thing is that I'm able to launch messages via "netcat" and "packetsender" and they all are being received by the server specific sketch (server.available() etc. ...).
I'm sure I am not aware about issues running an ESP as an AP and running Server software on it simultaneously. The Server examples on github only explain a connection to an existing AP by the server sketch but not combining an AP and Server into one sketch.
Heres my Server ESP Sketch:
Client Sketch:
