Getting Esp32 device id string

Easiest way to identify ESP32 device in your projects is by its MAC address. Below is an example that using String Builder to wrap up DeviceID string.

static char *get_deviceId() { uint8_t sta_mac[6]; esp_efuse_mac_get_default(sta_mac); str_builder_t *sb = str_builder_create(); char _temp[6]; sprintf(_temp, "%x%x%x%x%x%x", sta_mac[0], sta_mac[1], sta_mac[2], sta_mac[3], sta_mac[4], sta_mac[5]); str_builder_add_str(sb, _temp, 0); char *buffer = str_builder_dump(sb, NULL); str_builder_destroy(sb); return buffer; }
