FRDM-RW612 Sensors over Wi-Fi with http server

This demo shows how to use the P3T1755 on board temperature sensor, as well as the Accel4CLick and HeartRate4Click click boards on the Mikroe header, and send their data over wifi to an HTTP server which you can see using any device that can connect to the FRDM-RW612 Access Point.

This demo uses the monolithic WiFi configuration so the user does not need to load the WiFi Firmware manually.

3. Setup

1. First connect your click board to the MikroE header on the FRDM board using the GND pins as reference (not needed for the temperature example).
2. Open the project file of the sensor you want to test.
3. Connect your FRDM-RW612 board to your computer with the MCU link USB-C connector.
4. Build and flash the selected project to your board.
5. Run the example and open a serial terminal
6. Connect a device to the RW612 AP with the given SSID and Password, open an internet browser and type the IP given on the serial terminal.

Use the following settings for the serial terminal:

* Port: COM Port of your device
* Baudrate: 115200
*  Data: 8 bit
* Parity: none
* Stop bits: 1 bit
* Flow control: none

The IC marked blue is the on board temperature sensor P3T1755.

4. Results

If everything was done correctly you should now see the sensor data both on the serial terminal and on the webpage shown in your connected device.

You can change the SSID and password of the AP in source/main.c

#ifndef AP_SSID
#define AP_SSID "RW612_AP"
#endif

#ifndef AP_PASSWORD
#define AP_PASSWORD "0123456789"
