hello fgerenli ;
you say you will "give a try with a new function to read the new binary from UART " ?
is there achieved?
i have an idea about esp32 connect to MCU(like STM32) via UART;
then i want to upgrade esp32 firmware by STM32 via UART in bootloader step;
perhaps it is same to your function;

platform:esp32 esp-idf version:v3.1 I want to write a test case in esp32,it is similar with AT+CIPSERVER command; And i create two tasks, taskA and taskB . taskA is used to control wifi connection and socket_listen=socket() ,bind(socket_listen), listen(socket_listen,5) And then taskB is used to acce...

Update my test; Added code close(listen_sock);after close(sock); its work well too; but i have a question,i print out listen_sock ,it will be increased in every cycle; Is it correctly? Because i have been closed it in the end of cycle;I think the listen_sock will be released. I (3114) example: Conne...

hi,mikemoy and axellin ; About your answer,you just move while(1) to listen above; This modify do not close listen_socket and do not need to recreate new listen_socket, do not need to re-bind ,so you could work well in this case. But if you need to change your PORT to other, this modify is not helpf...

mark;
Does anyone have resolved this problem?

ahaha;
thank you very much ,WiFive;
it is all of the standard C library file operation functions;

hi,could you tell me something about file operation in esp32-idf;
i mean that there are some examples in esp32-idf;
but i can not understand how fopen,fprintf,fget,fclose worked;
i do not find the source code;
so i want to know where is the introduction about esp32-idf's file operation api;

hi friend rwel59:
i met the same problem with you;but i run mingw32.exe in folder msys32/ ;
and input make all;then it makes successful;
hope it could help you;

is there anyone could help me ?

hi，is there anyone used at-command to control esp32 bluetooth ?
i read the esp32 spec,its wifi control command is at-command,its the same as esp8266;
but i do not find the bluetooth control command ,is it at-command too?
or its have anyother control command?
please tell me ,thanks;
