XM125 Exploration Tool - Empty Graphs

I just got the SparkFun XM125 breakout board, and am trying to get it set-up with the Acconeer Exploration Tool. I’ve been able to flash the XM125 with the correct binary file, and have connected the sensor to the exploration tool with a baude rate of 115200. However, when I click “start measurement” on any of the basic detectors (distance detector, presence detector, even sparse IQ), the graphs are completely empty. There doesn’t seem to be any data coming from the sensor. I’ve repeated this process about ~10 times, while trying and failing to debug the system. Any help would be appreciated.
