You can set esp32 as AP/STA, client/sever, sender/recever in menuconfig. You can set whether to display delay time info in menuconfig. Now you can transfer data between esp and esp.

tcp_perf example
|
|
|
|
Using this example to test tcp throughput performance.
|
|
esp<->esp or esp<->ap
|
|
|
|
step1:
|
|
init wifi as AP/STA using config SSID/PASSWORD.
|
|
|
|
step2:
|
|
creat a tcp sever/client socket using config PORT/(IP).
|
|
if sever: wating for connect.
|
|
if client connect to sever.
|
|
|
|
step3:
|
|
send/receive data to/from each other.
|
|
if the tcp connect established. esp will send or receive data.
|
|
you can see the info in com port output.
