The entire solution occupies the least printed circuit board area. Both boards are very cheap, but the ESP32 costs slightly more. If that bit is 0 (i. Vamos agora definir a função que serve de callback para nos avisar sobre a situação do envio que fizermos. the first byte is an odd number), it is a multicast MAC address. The FTDI FT231x is also connected to the boot pins of the module, allowing for a seamless virtualization of the device. For example, the MAC address can set to be “1a:XX:XX:XX:XX:XX”, * @brief Set MAC address of the ESP32 WiFi station or the soft-AP interface. Before displaying text on the LCD, you need to find the LCD I2C address. 341 561 //The MAC address filter contains the list of MAC addresses to accept. It adds a CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4. The MAC address must be all uppercase and no delimiters.
