WIFI/BLE ARDBOX 20 I/O ANALOG HF MODBUS getting started

12 January 2024

WiFi

Hello everyone,

I'm a beginner in Arduino stuff sorry.
I've purchased this item: 007001001200 WIFI/BLE ARDBOX 20 I/O ANALOG HF MODBUS

I just can't get it work.

I've managed to upload a basic program to the board (both the Arduino Leonardo and the Wifi Module side) but the Wifi Module won't be recognized.

/code
void loop() { 
 Serial.println(WiFi.status());  
delay(5000);
}
/code

I'm only getting status 255.

Probably I'm doing something wrong. Please help me, where should I start?

I've checked all the documentation I could find but it didn't really help me further.

Thank you.

Endre.

Hello,

When using the Ardbox Wifi you need to take into account that you must program two microcontrollers:

The Arduino Leonardo, which should contain your main application and interact with the wifi module through serial communication. The WifiModule library facilitates this process.
The wifi module, which is an ESP32. This program should interact with the Arduino, and perform the wifi related tasks.

You can have a look at these posts, which might be of use to you:
