I have a 4 Zigbee node set up, 3 transmitters (identifiers are 333,444,555), 1 receiver. The reciever is read by Labview using the serial read. Each transmitter has a unique identifier and I can parse out who sent what packet when. Since I only have the one receiver, if I am getting a packet from one transmitter it ignores the other 2. My issue is that 1 of the transmitters runs at 20Hz, while the others at 1Hz. I think i am forced to run at the speed of my slowest component, so taht would mean my VI needs to be timed to run at 1Hz. What I would like to do is average all 20 samples from the faster transmitter, then record/perform calculations/display my data with the other two at a rate of once per second.
As far as I can tell from the packets received the data rate is fast enough that losing 1 or 2 packets from the faster sensor is a negligible loss if I do end up averaging them:

Since it is a stream that is continously running, slowing down the read loop with a wait crashes everything. The idea I have to make this work is to use reception of the 3rd sensor as my timing marker. So when 555 is received, take last 20 data points from 333, average them and then use that for other phases of the VI.
1) is this a good idea?
2) how do I implement it?
My VI is attached for reference. Ignore the switch case it does not work in this version, but everything is correct.
