Development of gps tracker firmware for simcom A7670SA module using Open CPU.
Budget: $30 – $250 USD
Firmware development for tracker in C using simcom's OpenCPU library for the A7670SA module.
Firmware Features
voltage analog letter
Ignition reading through specific input
accelerometer reading to know if you are moving or standing still
output activation
update via ota
Data transmission over TCP socket
send command to configure time and output activation
Sending an alarm when there is a lack of main battery voltage
Sending a data packet by time with the following information (package type (1 position, 2 power failure alarm), equipment series, latitude, longitude, GPS date, number of satellites, direction, speed, voltage, internal battery , ignition , output status)
Data will be stored if there is no signal and sent in fifo, even if there is signal, but if there is something in the queue, a new packet must be placed in the fifo queue.
data transmission based on ignition timing, i.e. different timing depending on ignition;
