Hello,
I need some information regarding the path in which Connman saves the
information. Connman saves the settings of each network under /var/lib/connman.
We are planning to use Over the air software update for our product. Since this
information are stored under /var/lib/ directories, these informations are lost
after the software update. Is it possible to change this directory in Connman
to some other location. We have a data partition which is not modified during
the software update. It would be helpful, if we store the connman and ofono
related information in this partition.
Any information on this topic would be useful.
I am currently using Connman version 1.35 and oFone 1.21. Linux kernel:4.9
Mit freundlichen Gr??en / Best regards

I use the same setup and my rootfs is set as read only.
I suggest to create a /data/var/lib directory at runtime.
You can
- have a symbolic link from /var/lib to /data/var/lib
- do a mount --bind
- use an overlay file system
I personnally use the 3rd solution
You can look at the systemd unit which mount this folder
