Hi, I tried to use MC7304 or MC7430 in embedded linux 3.14.2 (ARM), with the latest driver, the modem was detected, but I don’t know how to make it online.
Modem driver S2.27N2.41(GobiNet & GobiSerial),
With MC7304, I detected /dev/ttyUSB0~2, /dev/qcqmi0, and eth2
With MC7430, I detected /dev/ttyUSB0~2, /dev/qcqmi0, /dev/qcqmi1, eth2 and eth3.
I checked SIM card (has ip address) is in the slot, no modem manager and network manager in my controller.
Reference to the “Technical Note - Migration from DirectIP to RMNet on MC73xx.pdf”. I sent some AT commands (copied from the doc) to /dev/ttyUSB2, but I still could not get the ip.
# ifconfig eth2 eth2 Link encap:Ethernet HWaddr 06:EF:1D:30:9F:08 BROADCAST NOARP MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Reference to the “Linux QMI SDK Application Developers Guide Rev1.26_1.pdf”. I unziped SLQS04.00.05.bin and copied it to my controller. Then run “connectionmgrarm”, “LTE Data Session started successfully” was show up, but the modem still offline and no IP address.
I confused how to use this modem. SLQS04.00.05 is over 900M, do I have to use this packet ? Is there any easy way to make the modem online?
I would appreciate if anyone can help me out here.
