Detailed Description

Processing Task Implementation File.

This file contains the implementation of the processingTask function, which is used to handle processing operations in a FreeRTOS task. The task is responsible for processing sensor data and creating a JSON string for network transmission.

Function Documentation

createJson()

bool createJson	(	const sensor_data_t &	data,
		char *	buffer,
		size_t	bufferSize )

Create a Json object.

This function creates a JSON string from the sensor data and stores it in the provided buffer. The JSON string contains the following fields:

• steps
• humidity
• gas
• fall_detected
• device_battery
• heart_rate
• noise_level

Parameters

data
buffer
bufferSize

Returns

true

false

processingTask()

void processingTask

Processing Task function.

This function handles processing operations in a FreeRTOS task. It reads sensor data from a queue, processes it, and creates a JSON string for network transmission. The task runs in an infinite loop, waiting for data to be available in the queue. When data is received, it is processed and sent to the HTTP queue for transmission.

Parameters

pvParameters
