Extra Serial data from Xbee to Xbee

Here's the setup:


Here's what I get when I open the serial monitor for COM8 (the xbee attached to the PC):

It also goes through different symbols and letters: (# ! " $) and (W X U V G) but always the cursivey 'f' at the beginning and a '~' at the end of each line.


I am running the example code PhysicalPixel to test which does not have any serial.print()[ing]. The spam repeats each line about once a second when and only when both Xbee's are powered. Is there some kind of keep alive/communication signal going on between them and if so how can I filter it out?

The sketch does work despite this oddity; H turns the light on and L turns the light off as it should.

Maybe this doesn't matter but the RSSI lights are solid green on both Xbee's.

For the project I am working on it does not work. I am trying to send multi character serial commands like 'compass' and 'light'.

Xbee's are configured as such from XCTU with latest firmware. They are Series 1 Xbee's.

I changed the IR field (sample rate) to 1, I'm not sure why it was 1388.

Does anyone know what is causing the spamming of gibberish when both XBee's are powered?
