converting MAC address into string
Posted: Thu Sep 24, 2015 6:10 amHowdy,
I am converting MAC address into string. That string I want to save in a variable and publish that variable value using MQTT. Any guess how to do it
os_printf("rdaddr: %02x:%02x:%02x:%02x:%02x:%02x "tsaddr: %02x:%02x:%02x:%02x:%02x:%02x " "bssid: %02x:%02x:%02x:%02x:%02x:%02x ""addr4: %02x:%02x:%02x:%02x:%02x:%02x\n", MAC2STR(probe_request->rdaddr),
MAC2STR(probe_request->bssid));
The os_snprintf does not support it shows error
