Ping from ESP32

Hi,

What APIs can be used to ping to an address from ESP32? I can see that there is ping_send in lwip/apps/ping but this function header is not available. The header file only provides ping_init().

Thanks. Doesn't esp_wifi_get_mac() get the address from EFUSE?

Re: USB Serial on UART2

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...

USB Serial on 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...
