I’m trying to parse this string:

+CGDCONT: 0,”IP”,”free”,”10.158.88.34“

In bold are the items i’m interested in.
My first attempt was to use this pattern:

"+CGDCONT: %d,"IP","%*s","%d.%d.%d.%d""

with it, only 1 variable is parsed.

Then, I tried:

"+CGDCONT: %d,"IP","free","%d.%d.%d.%d"  // the string "free" is hard coded

It works but “free” might not be always “free”, so I need a way to ignore it.

Then, I tried:

"+CGDCONT: %d,"IP","%s","%d.%d.%d.%d"  // the string "free" is no more optionnal

with it, 2 variables are parsed. The second one (%s) is parsed as

free","10.158.88.34"8  // 8 is ascii char 8.

How should I do?
