Any success with wall box with esp-idf component for gc9503

Hey, I have a esp32s3 based box with touch screen (link below), which works with the board support package for it, but I can't get it to work with the esp-idf components like https://components.espressif.com/components/espressif/esp_lcd_gc9503/versions/3.0.1 . I need that because the BSP doesn't sup...

Can't send data if two netifs (wifi + gsm modem)

I'm using a small sample application to figure out how I can have two network interfaces active : wifi when all is well, but fallback to cell phone otherwise. The demo app works with one network interface (either) but not when both are started. Even the initial communication (a simple web query) fai...

how to debug touch gt911 (works in demo program)

I have one of these Sunton boards esp32s4827s043 with an esp32s3, a 480x272 display, and capacitive touch (they say). I was able to get the display to work from a barebones esp-idf program, but not the (gt911?) touch.
See https://sourceforge.net/p/esp32s3-4827s043/code/ .

Any clues on how to debug ?

Re: TCP connection between nodes, should select raise exception ?

Well, the select() API was built for three things, one of them being exceptional conditions. And the other side in the communication (trying to read) does get such a signal. Three independent sets of file descriptors are watched. The file descriptors listed in readfds will be watched to see if chara...

TCP connection between nodes, should select raise exception ?

Hey, I have pretty standard code based on BSD socket select. Shouldn't select() catch the condition that a socket is disconnected and can't be written to ? Error message changes after the first error, then keeps on going instead of getting an error condition raised. https://sourceforge.net/p/espalar...
