GPS tracker (STM32+SIM868) prototype firmware development part2

Hi all,

I need help with firmware development for a GPS tracker prototype I'm building.

It will be based on the STM32 microcontroller and will use the SIM868 as the communications module for GPS/GPRS/BLUETOOTH.


- Set up communication between STM32 and SIM868 over UART using AT commands

- Sending GPS data to remote server over TCP/IP using a defined communication protocol (GT06/TK06 or other, open for suggestions)

- Reading and configuring of device parameters using SMS

- Reading accelerometer data over I2C using interrupts

- Reading 1 analog input and processing it using interrupts

- Reading 1 digital input and processing it using interrupts

- 2 digital outputs to control relays for example


- Reading and configuring of parameters using bluetooth, USB (COM port)

- Sending GPS data using MQTT

Hello, I read your specification carefully. I built very similar project before, Your project is almost same as mine that I made before. In my last project ,I used STM32407 + SIM808, and send GPS data to TCP/IP server. Flere
