Subject: Connecting Zigbee nodes thru UART
Dear fellow engineers,
I'm currently trying to have two ZigBee nodes communicate with each other thru UART, instead of 2.4GHz radio.
My ZigBee nodes operate on ZStack MSP2618 - 2.3.1 - 1.4.0.
I guess it's possible if I modify some of the code of ZStack.
For example, outputing all the mac-level frames of Node-A from its UART port, and then into the UART port of Node-B.
It looks like there are some data-structs within zmac.c and others that we can intercept, and then simply output, by invoking a function like HalUARTWrite().
I'm in my first step of outputing Beacon Request, which should consist of 10 bytes according to the specification. But I'm not quite sure where in ZStack code I can intercept this exact data.
Any advice will be welcomed.
