Hi,

I am looking at a method to uniquely identify every ESP32 device .Is the MAC address obtained using the 'esp_wifi_get_mac()' truly unique for every device?

OK. I'm using UART0 as console and UART2 as additional serial. Serial out(fputs, frpintf) on UART2 files work well but input (using fgetc) from UART2 device file drops characters at times. Any pointers to what I might be missing?

Hi, Yes, the code which considers the non-blocking behaviour. By inconsistent, I mean that fgetc (stdin) works fine, whereas a fgetc from a file opened on UART device '/dev/uart/0 or '/dev/uart/2' does not give the same result. Some characters are dropped or ignored. Seems like I'm missing some conf...

Hi All, Trying to use UART2 on ESP32 as an additional serial port - no flow control. The example code in esp-idf: uart_events work fine for UART2. However, on using fgetc and other file operations on /dev/uart/2 the results are not consistent. Are there any additional settings or config to enable fi...
