/*
udp_perf example
Using this example to test udp throughput performance.
esp<->esp or esp<->ap
step1:
init wifi as AP/STA using config SSID/PASSWORD.
step2:
2017-04-10 08:39:04 -04:00
create a udp server/client socket using config PORT/(IP).
if server: wating for the first message of client.
if client: sending a packet to server first.
step3:
send/receive data to/from each other.
2017-04-10 08:39:04 -04:00
you can see the info in serial output.
