XBee S2B Pro Sample Rate Question

I’m having an issue with S2B Pro IR Sample Rate.

I’ve set the IR Sample Rate to “0x32”, this means a 50ms IR Sample Rate or 20Hz.
Baud Rate is set to 9600.

I have a 3-axis analog accelerometer plugged into three different XBee ports, set as analog.

After I read the data I get 14 samples per sec instead of the 20 I was hoping for.
I understand I am doing something wrong, can’t seem to find where is the issue.

Thanks in advance,

Could be a throughput issue. The mesh based products are not well suited for streaming data. Try telling the system to transmit after taking two samples.
