vehicle tracking device custom firmware

Job ID: 30643467

Budget: $30 – $250 USD

I have Arvento imt14 branded vehicle tracking devices about 200 pcs. I want to custom firmware to the devices. The firmware must send various gps data and vehicle ignition status to my own server over TCP/IP. The devices original firmware send GPS data to Arvento's server so I dont use their server anymore.
The devices has STM32F103VET6 , Telit GE865 GSM modem and Ublox Neo6M GPS module
Also every device must have a id number in firmware.
We have no any PCB schematic so you must find connections from sample which will sended by me
