Hi
I try to make a simple network application to use Easylink.
But, I don't know what differences between Easlink and TI 15.4 Stack are.
I'd like to compare with TI 15.4 stack and Easylink.
Maybe, some of the functions are not supporting such as security.
Could you let me know the difference refer to table as below ?
I try to use rfWsnConcentrator and rfWsnNode example when I can make a sensor network to use Easylink.
1. Do rfWsnConcentrator and rfWsnNode have security feature? If not, what example can I follow to implement security feature?
2. Do rfWsnConcentrator and rfWsnNode have device association and disassociation feature? It is because I cannot find any easylink API related to device association and disassociation.
3. Could Clear Channel Assessment (CCA) Cofiguration replace CSMA/CD or LBT function ?
