Today I use D-duino to test WiFi mesh network. D-duino has a 0.96 OLED display and is very suitable to do IOT work.
OK, Let us Start.
First, prepare two D-duino. Of course ,more is OK. D-duino support 87pcs to make its ad-hoc network.
Step 1: Connect
The 1st D-duino is connected with computer. You can see the chip ID is 1305567. I put the other two on different areas. They can keep connection with each other.
You can build a local network like the picture.
Step 2: Result
You can open serial monitor of the Arduino IDE. The result will show on the window.
The other two devices send their command to the first D-duino. Now we built a wifi local network successfully,
we can extend more and more modules!
