If is this case valid, is there a possibility to keep GPS chip running while
CPU will be supended? I need this in case when I'm on a trip recording a
track and I stop in a pub for a few hours and I want to save some power
meanwhile.
I made /etc/apm/resume.d/ script which powers up GPS but I can't test it right
now becase it is too bad wather to get fix here.
BTW: What do you think is the best way to detect that GPS should be powered up
after resume: seach for tangogps process or save GPS state in suspend.d
script to some file (i. e. /var/run/gps_state) and enable GPS accordingly?
Thank Mike for exhaustive explanation.
(Sorry Cédric)
