WiFi¶
Brief¶
Sentry2 has an on-board ESP8285-WiFi chip which can be programmed by Arduino IDE directly to realize online-recognition, image transmission, AIoT and other applications. ESP8285 can be used as a controller for K210 which is help for AI programming without external device.
Development Environment¶
Add ESP8266 Board¶
Firstly, Download and install Arduino IDE:
https://downloads.arduino.cc/arduino-1.8.19-windows.exe
Run Arduino IDE and Open “File” >“Preference”
Input the URL to “Additional Boards Manager URLs” and click “OK”
http://arduino.esp8266.com/stable/package_esp8266com_index.json
Open“Tools”>“Board”>“Boards Manager”
Search “esp8266” and click “Install”
Simple Test¶
Open “Tools”>“Board”>“ESP8266”>”Generic ESP8285 Module”
Open “File”>“Examples”>“ESP8266”>“Blink”
Connect Sentry2 to PC via an USB-TypeC cable. Open “Tools” and do seme settings as shown in the bellow Buildin Led：“4” CPU Frequency：“80MHz” or “160MHz” Upload Speed：“57600” Reset Method：“no dtr (aka ck)” Poart：“COM xx”(The USB Com Port)
Push the Stick button downward and hold it(NOT Vertical Press), Click “upload” to start compiling and uploading, hold the Stick button downward until the screen shows the xx% progress.
Wait firmware uploading until 100%
Restart the Sentry and runs the “Custom” vision, the Blue WiFi LED will be keep bright and the Custom LED will be blink.
WiFi Demo¶
Some open source WiFi programs are provided.
