Hello DFRobot,I couldn't find the library for it in Arduino ADE. I downloaded the CPP and H files from your Wiki but errors while compiling. :-(Please help. Thanks.

Hi DFRobot Support, the DFRobot_WiFi_IoT_Module library does not compile in the Arduino IDE (v2.3.1) for Gravity WiFi IoT module v2.0.0. I wanted to check the module with the sample code 1-3 from https://wiki.dfrobot.com/Wi.... It does not work so far. It is connected through UART to Arduino Nano 33 BLE Sense Rev 2 (3.3v). Do you have an updated module or additional example to check the module?

Yes, it come with the wires.

Hi DFRobot,

does this module support blynk?
