Develop board and firmware for a serial-to-GPRS bridging app with custom I/O, process, and connectors. Programmer will use MQX RTOS, RTCS with UDP & TCP stack (GSM module does not embed a TCP stack), manage GPRS connexion (ie. AT commmands, PPP).
See the attached document for hardware and software specifications overview.
Scope of work:
1. Board design (PCB design, component selection, validation)
2. Firmware development (for Freescale Kinetis using MQX RTOS/RTCS with Code Warrior)
3. Supply of 2 prototypes (GPRS module and DigiXBee will be provided by us)
5. Manufacturing file
Code to be provided with full comments (for Code Warrior)
