hannez0101 · July 4, 2024, 10:30am

Hi

I’m trying to get gpsd to work with my module but I’m having no luck. I have tried with gpsd /dev/tty/USB0 but it can not find any device whit that name. Anyone how know what to try? Kurt

Always start from checking with cat /sys/kernel/debug/usb/devices

You don’t have a modem [attached to USB], so you should not expect to see /dev/ttyUSBx

How do i connect my modem to USB?

Bean.Wang-Q · July 4, 2024, 1:03pm

If so, the nmea port should be

/dev/mhi_LOOPBACK

If so you should send the command to enable the GPS on AT port (/dev/mhi_DUN) .

hannez0101 · July 4, 2024, 1:26pm

hi
What command should i use for If so you should send the command to enable the GPS on AT port (/dev/mhi_DUN) .

i have tried with gpsd /dev/mhi_LOOPBACK
then gpsmon but no output

Bean.Wang-Q · July 5, 2024, 12:57am

Please send the AT
AT+QGPS=1

hannez0101 · July 5, 2024, 11:56am

Hi
I trying the command in my terminal but it doesent work Do i have to have some software to print the AT command in if so what is the command to use? Thankfull for answer!

Bean.Wang-Q · July 8, 2024, 12:48am

You should send the AT command AT+QGPS=1 in the /dev/mhi_DUN
and then you can check the output in the /dev/mhi_LOOPBACK port.

hannez0101 · July 8, 2024, 9:50am

i cant find the file /dev/mhi_DUN its not in the dev directory

Bean.Wang-Q · July 8, 2024, 1:22pm

Please try the pcie_mhi driver.

hannez0101 · July 8, 2024, 4:08pm

hannez0101 · July 11, 2024, 11:29am

Bean.Wang-Q · July 11, 2024, 12:58pm

Let’s test
AT+QGPS?
AT+QGPS=?

hannez0101 · July 11, 2024, 1:44pm

hi i try with AT+QGPS=? and AT+QGPS? give this output

Bean.Wang-Q · July 11, 2024, 3:34pm

If so it should support the AT+QGPS=1
