accidents-system's Issues

use JSON middle ware

use JSON middle ware to be able to serialize and manipulate all kinds of data.

fix MPU bugs

Fix MPU bugs, run unit tests and make a commit.

ESP semaphores

1 - Create semaphores to handle shared resources between HAL tasks and application layer tasks
such as read and write buffers and similar resources.

2 - Create semaphores for the purpose of synchronization between TCP/IP read and write tasks or any other task
(both tasks can't work at the same time).

calibrate MPU data and calculate the accident's signal

use the following research paper to calibrate and calculate the suitable MPU readings to detect an accident.

add our custom boot-loader

add our custom boot-loader and it's unit test file(or guidance)

use web sockets

Use web sockets directly as the only way to connect to the cloud,
without using MQTT as a middle ware.
This requires adding additional data fields to distinguish between devices and various data entries.

USART received data buffering

MQTT task is not working

unit tests for both ESP and MQTT middle ware are working properly,
when using both of them together in MQTT task something goes wrong and no data is received at all on the receiver side.

GSM test

MPU in RTOS

1- use the mpu_read() function as a task in OS.c file
the task should read data periodically and save it into struct.

2- in mpu_test file, you should refer to how to extern the mpu_data_struct anywhere to be used.

if you want to test your code you might create a dummy task which reads the mpu_data_struct periodically and only printf the results.

note : no need for semaphores in the whole thing.

MCAL & HAL documentation
