Most GPS receivers don't have enough precision for any timing.
Would you recommend a specific one?
Apparently, this last part cause the WWAN card not to be handled by
thinkpad-acpi, which would otherwise provide rfkill support (usefull to save power, something I'd like to improve)
Soft rfkill is always available through wwan driver.
What should I do to enable it? At the moment it is not showing in rfkill list, even while I monitor the lack of satellites fix with:
echo 'AT^WPDGP' > /dev/ttyUSB0
cat /dev/ttyUSB3|grep GPGSV|grep -v 00
*$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
I read http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module which mentions /sys/devices/platform/thinkpad_acpi/rfkill/rfkill0/state, but I believe it depends on the ACPI entries to show up.
Thanks
