CC2538: Send data from end device to coordinator

James Mel

Part Number: CC2538
Other Parts Discussed in Thread: CC2650, Z-STACK,

Greetings,

I'm using CC2538 as a coordinator and CC2650 as an end device. I want to send some data from the end device to the coordinator. I opened the ZCL API document (in Z-Stack Home 1.2.2a) and it's all about using attributes.

1- How can I use attributes to send data from many end devices to the coordinator? For example, if I have many temp sensors send their readings to coordinator at the same time, would the attributes help?

2- Is there any other ZCL function to use to send data? or I should use one of the AF layer functions as AF_DataRequest()?

Thanks in advance

There’s temperature example for CC2650 in Z-Stack Home 1.2.2a. I suggest you to study it first.

Hi YiKai,

I have already studied it. It uses an attribute that the sensor writes the temp in.

My question is:

if I have many sensors, they will all override the same attribute. How can I read the attribute value of each sensor alone?
