Tool/software: TI C/C++ Compiler

I am studying zigbee with (Z-Stack Home 1.2.2a.44539)

1.I want to adjust code using RSSI value.

So. in the event loop,

if ( events & SYS_EVENT_MSG )
{
while ( (MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( zclSampleThermostat_TaskID )) )
{
dd_rssi = MSGpkt->rssi;

But, rssi values are always 8 without distance.

How can I call real rssi value?

2. I can see average RSSI values Using Smart RF studio.

I think the value save 0x6198 in mcu register.

Can I call this value in IAR Embeded Workbench?

example) ave_rssi = 0x6198register

thanks

You should use MSGpkt->LinkQuality to get LQI and convert it to RSSI which you can refer to formula in sunmaysky.blogspot.tw/.../conversion-between-rssi-and-lqi-in-z.html

Thanks your reply

But, I adjust code to your opinion LQI values don't change

LQI vlaues always 8 when the distance between End device and Coordinator more far.

So, I can't use this way.

Please help me more

You should move LQI related code into "case ZCL_INCOMING_MSG:".

Sample Thermostat (in Z-Stack Home 1.2.2a.44539) don't use afIncomingData function

afIncomingData ->afBuildMSGIncoming

Where I use afIncomingData function?

please help me more detail...

ex) I use afIncomingData function at case ZCL_INCOMING_MSG then ....

I am beginner at Zigbee and C programing...

All of messages would go to afBuildMSGIncoming first and pass to ZCL_INCOMING_MSG for application processing so you can try to get LQI in afBuildMSGIncoming (in AF.c).

I didn't find All reference of 'afIncomingData'
Could you sent me a z-stack file of Sample(TemperatureSensnor, Thermostat, HeatingCoolingUnit)?

It's afBuildMSGIncoming() in AF.c.
