Can anyone help me?

What is the answer of the following commands?

cm radio cm data
The default PDP type used for the data connection is “IPV4V6” which is not supported by some network operators.
Try to modify it with this command:

cm data pdp IPV4

Then retry to connect with

cm data connect


The problem is gone after I updated legato framework by executing the command:
$ instlegato build/ar7
