Getting password on Roomba j7+

Hello. I just got myself a Roomba j7+ and am having trouble fetching the username/password from it using the methods listed here. I’m also seeing the same thing on the dorita980 project, so I suspect this is more about the j7+ needing some new mojo vs. the older models, but that’s purely a guess.

Here’s the behavior I’m seeing when trying to fetch the username/password:

[jdiegmueller@nv-dc2-rproxy1 roomba]# ./getpassword.py -R 10.245.2.102
