https://doi.org/10.1057/9780230119062Email and QR (Quick Response) codes are both ubiquitous, and projects with the ESP32 microcontroller incorporate both technologies. Transmitting information or images by email with the ESP32 microcontroller and generating a QR code instructing an ESP32 microcontroller to control a device are described in this chapter.

ESP-MESH nodes do not require direct contact between all nodes, as the ESP-MESH protocol ensures that a message reaches the destination node by routing the message through the network (see Figure 3-1). The node
