How to receive io samples from one specific node on a network?

[zgarnes17]

Currently, I am working on a project that has four sensor nodes with Zigbee Modules - 802.15.4 XBee, S2C hooked up to geophones sensors. My python code uses the add_io_sample_received_callback function and can receive all the incoming io samples from each of the different nodes on the network. However, I need a sample rate of around 150Hz, which can't be possible if I am receiving samples from every node at the same time. My way around it was to have to coordinator only listen to a specific node of a set amount of time, then rotate around the network. However, I am not coming up with any good way to achieve this. Is this even possible? If not, would anyone have a solution to my problem of achieving a fast enough sampling rate?
