Hi everybody, I have to send multiple files (about 1000) content (for a total of about 1 MB or more) via MQTT to a remote broker. Since ESP32-WROOM-32 has limited RAM I can't read all files and put in a buffer before publish it. Is there any way to perform a "chuncked/segmented" publishing with esp-...

I have tested a simple example and it does work as long as you use the function calls I posted. Thanks for testing @WiFive. This means my code could have problems. May I ask you to provide the source code of your test example (and sdkconfig file if possible)? Did you setup the CONFIG_CONSOLE_UART_C...

Yes, the function I posted. I don't know why it doesn't work.

If I share my test code, could you please check if you find something is wrong?

Maybe @ESP_igrr could also shade some light on this.

Thanks

Sorry, this is only documented in the UART API reference at the moment — wakep only works on the IO MUX pins: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/uart.html#_CPPv425uart_set_wakeup_threshold11uart_port_ti (see note in the function description) Thank you @E...

I think you might have to do this PIN_FUNC_SELECT(PERIPHS_IO_MUX_U0RXD_U, FUNC_U0RXD_U0RXD); PIN_FUNC_SELECT(PERIPHS_IO_MUX_U0TXD_U, FUNC_U0TXD_U0TXD); Unfortunately, it seems not working. This my code: PIN_FUNC_SELECT(PERIPHS_IO_MUX_U0RXD_U, FUNC_U0RXD_U0RXD); PIN_FUNC_SELECT(PERIPHS_IO_MUX_U0TXD_...

Is uart0 initialized and functional before sleep? Yes, it is. UART0 is working perfectly and I can send commands (via U0TX GPIO1) and receive (via U0RX GPIO3) replies from the external module. Infact, with the "default" Configuration everything works as expected. The problem is to sent debugs on UA...

Hi everybody, I'm testing "esp_sleep_enable_uart_wakeup" function. I have connected to UART0 (GPIO3 U0RX, GPIO1 U0TX) an external LTE module and I would like to wake up ESP32 when it is in light sleep but the external module send a particular string on the UART0. I have done a very simple test. It s...

Hi everybody, I have started working on esp_http_server and I used "restful_server" example as starting point. So far so good. I would like to know the IP of the client connecting to the esp_http_server (esp32 is NOT in softAP). I see that in "components/esp_http_server/src/httpd_main" the function ...
