Embedded Firmware for C2530 MESH with Z-Stack

Project Description Introduction: Program setup is consisted of 2 type of Zig bee devices both developed on the CC2530 from Texas instruments. The firmware shall be based on the Z-Stack 3.0 . The mesh shall be a self healing MESH with depth of network limited to 4 hops. The MESH shall be a time synchronized MESh. The C++ source code of the project is a deliverable. - Single Coordinator - Routers (max 255) Coordinator: • This purpose of this CC2530 firmware is to monitor and control sensor circuits using zig bee routers. The coordinator shall send receive data via UART from a Controller unit based on Renesas S3A7 (not in scope of this project) on Pin P1.5 & P1.4 of the CC2530 (256K) • The single Coordinator shall be able to maintain Routing table to address 255 routers depth of network limited to maximum of 4 hops • Coordinator shall manage the network by sending/receiving l instructions to/from routers in the MESH. • The coordinator shall have full functionality of Device Binding & Device Discovery controlled from the S3A& controller via the UART • The Mesh shall be operational on simplified AODV (Ad-hoc On-demand Distance Vector) method limited to 4 depth of network. • Coordinator shall receive and respond to serial requests to retrieve child list (Routers list) • Coordinator shall notify the S3A7 controller with any added/removed router • S3A7 Controller shall be able to trigger the coordinator to change any router status • Real time clock is received by the CC2530 coordinator from the S3A7 Controller • All devices shall use their extended address ( optional) Routers: • The router are based on a CC2530 (256K) device and is battery operated . • Each router shall receive data via UART from a sensor module on Pin P1.6 & P1.7 of the CC2530 (256K) • All devices are designed to be routers and shall sleep and wake up in time to a time synchronous • All routers shall join the network automatically to the coordinator, PAN ID and security code shall be entered to code as static value • All routers shall maintain a Routing table for a maximum of 3 hops ( final hop to coordinator) • All routers shall have a neighbour table up to 4 neighbour only • Routers shall be able to sleep and wake up in a time synchronous manner as set through the coordinator • Routers shall notify the coordinator about battery status sent over the UART • All messages shall be time stamped from the router
