/*
|
|
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:
|
|
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.
|
|
you can see the info in serial output.
