RTOS/CC1350: How Collector is handling reception of multiple data coming from several different nodes ?

Tool/software: TI-RTOS

hello all,

Consider one collector is connected with 50 nodes and all nodes have joined the same collector and sends the data periodically.

My question is at same instance how my collector will take care of all the messages coming from 50 devices at a particular instance?

How the 15.4 MAC take cares of this ?

Thanks,
Ajmal

Where there is a message comes to collector, collector know which short address it comes from.

Thanks Chen for your fast response.

I am not getting the first point where the collector will receive any message from sensor.
Than i need to know how it is handling multiple messages at a time.

Collector receives messages from sensors in dataIndCB().

As YK mentioned, all the incoming messages to the collector will be received in dataIndCB it doeswnt matter if it is only 1 sensor sending data or 50 sensors sending data, all the messages will be received in the same call back. Also, all messages will have a source address which will indicate from which sensor this data came from.

Thanks Chen

i want to know if 50 nodes are sending data at 50 kbps and my data packets also high . how the collector will handle all data's at the mac layer.

is it having any queue, if yes i want to know en queue. d queue of all messages.

I don’t think it’s feasible to have 50 nodes doing 50kbps simultaneously.
