Pi -> USB -> ME906E

Thu Jan 16, 2020 2:47 pm

Good day,

I have a school project with GPS tracker. I have Raspberry Pi, HUAWEI ME906E (4G modem, GPS) and M2 to USB adapter with SIM slot. I need to read data from GPS and connect to the Internet through 4G modem. For now, I connect all hardware but I don’t know what to do next. I read different documentations in the internet but I couldn’t reach to read any data from GPS.

Command “dmesg | grep tty” show me:

[ 0.000000] Kernel command line: coherent_pool=1M bcm2708_fb.fbwidth=656 bcm2708_fb.fbheight=416 bcm2708_fb.fbswap=1 vc_mem.mem_base=0x1ec00000 vc_mem.mem_size=0x20000000 console=tty1 root=/dev/mmcblk0p7 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

[ 29.796363] qcserial ttyUSB3: Qualcomm USB modem converter now disconnected from ttyUSB3
[ 29.997963] usb 1-1.2: Qualcomm USB modem converter now attached to ttyUSB0

Command “lsusb -d 03f0:581d” shows:
Bus 001 Device 005: ID 03f0:581d HP, Inc lt4112 Gobi 4G Module Network Device

Command “cat </dev/ttyAMA0” stacks and show me nothing.

Thank you in advance for your help.

Have just chacked this hardware under Windows 10. Internet and GPS working fine. But still unclear how to setup this hardware on PI...
