EHS6 SYSLOADING loop | Telit Cinterion IoT Developer Community

Hi all, I've been attempting to work with the EHS6 but I'm running into some trouble that i was hoping someone could help with. The device powers up using the auto-on pin and outputs ^SYSLOADING roughly every 2 seconds and won't respond to any AT commands which I send over the TX/RX pins. V180 stays constant in the specified range. Vcore starts out in spec but drops to ~0.2V in sync with the sysLoading messages. I don't believe this is due to variations on the Vbatt line as it happens with both a 1S lipo as well as a benchtop supply and from my understanding it doesn't even get far enough along to pull anything over 70mA.
I realized I left the ON pin floating since I am using Auto_on to start. Should I pull ON low or is floating ok if I don't plan on using it?
