channel masking in TIMAC

The coordinator in TIMAC uses a fix channel for communication after it forms the network. There is no way for multiple nodes in the same network to send message using different channels.

is there any mechanism using which we can make the coordinator  to accept data from multiple nodes using different channels.

CC253X only has one RX HW so the coordinator is not possible to accept data from multiple nodes using different channels.

Sir, what about CC2520,can it be used for data access from multiple nodes using multiple channels

CC2520 is a transciever and one RX is the same to CC253X.
