Hmm, don't think so:
# ps | grep connman | grep -v grep
3465 root 8948 S connmand -d
# ps | grep ofono | grep -v grep
319 root 5656 S ofonod -d
# systemctl status connman
Active: inactive
# systemctl status ofono
Active: inactive
# kill 3465
# ps | grep connman | grep -v grep
# kill 319
# ps | grep ofono | grep -v grep
# OFONO_QMI_DEBUG=1 ofonod -d
# connmand -d
# ps | grep connman | grep -v grep
4912 root 8944 S connmand -d
# ps | grep ofono | grep -v grep
4910 root 5712 S ofonod -d
# journalctl -u ofono > ofono.log
# journalctl -u connman > connman.log
same contexts in the log files, what I could be missing?
Thanks Jonas
