Hardware Serial2 Example Code. 对于单片机来说串口是最常用的功能之一本文将对Arduino core for the ESP32的串口使用做个说明. It is designed as an extremely lightweight publishsubscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. Serial2 is inialized as 115200 8N1 I dont know if that matters a lot since it only writes what it readsIt should work ok but I get very similar to the same. It supports WiFi and Bluetooth dual-mode communication and features small size ultra-low power consumption on-board charging circuit and easy-to-use interface which can be conveniently used for smart home IoT industrial IOT applications wearable devices. This seems to require using Simulink to send the new program.
Mar 27 2019 Its not quite a simple as you might expect though the BLE server and client examples for the ESP32 devices distribution dont work straight out of the box they really should because they use different.
