Just curious to know if this 4G module is compatible with Raspberry pi board?.
probably not, but if you add driver to the code, possibly yes.
Hi. I am using Ubuntu 16.04 image and run the quectel program with 4G module. I am getting the following which I could not understand why the wwan0 disappear when we call dhclient,

Helloļ¼it looks strange, when you use dhcp to get IP, but /quectel-CM exit, let me have a look.
Helloļ¼Could you please show these logsļ¼
-
Do this command to check deviceļ¼ls /dev/ttyUSB*
-
After you execute ./quectel-CM &ļ¼and after you dhclient wwan0ļ¼if wwan0 is downļ¼please check device againļ¼ls /dev/ttyUSB*
-
if /dev/ttyUSB* is exist, please do minicom -D /dev/ttyUSB2, and do these commands to check 4g module statue:
- at+csq
- at+ccid
- at+cgreg?
Hi. Check my reply.
-
ls /dev/ttyUSB*
ls: cannot access ā/dev/ttyUSB*ā: No such file or directory
-
quectel-cm quit, because of no wwan0 device and gives same result for āls /dev/ttyUSB*ā.
-
Not able to do since there was no wwan0.
so your image donāt recognise the 4g moduleļ¼ you donāt have /dev/ttyUSB*?
@Jackzeng No. The module initially mounted on the ttyUSB0-3 and automatically unmounted only after I call quectel-cm & dhclient wwan0. My dmesg message is as follows,

It is even automatically disconnected shortly after I reinserted the 4G module. Check my updated dmesg log.

@Jackzeng Thanks. I also found another issue is that, whenever I use the soft reset ārebootā command, the BPI-R2 reset without any issue. However, the 4G module is mounted even after mounted and got the IP address; But internet is not working. I use hard reset or power ON/OFF, then the 4G module is working fine with internet facility. Let me know your input if any on this issue and If I have any other better way to reset the hardware by some other command?.
TIA.
Hello,
- these are update files & tool
-
update fileļ¼https://drive.google.com/open?id=1BdZ6-4T7QNXzvhD_YQ8C-vbjQobjm05o
-
update toolsļ¼https://drive.google.com/open?id=1F88FThUudUSrXZGN2bDbOgAvKfCfwGNm
- Did you mean when you reset the R2, you also want to reset 4G module?
@Jackzeng Thanks for these updated files. Let me check it and get back to you.
- Yes, I want to reset the 4G module as well.
Also like to know whether I should update the firmware on the 4G module by using this update tool?. Any kind of instructions is appreciated.
TIA.
is here any plan to support multiple 4G /LTE cards/connections on this module, after all , this is a router , one 4G connection may not be enough to be shared among those interfaces ?
or is there any solid workaround for this ?
Hello,
I have just bought the BPI-4g module, however there are no instructions or any documentation with it at all.
It seems to be a newer model with two USB connectors. What is the purpose of having 2 ports? Which one to use?
I plan to use the module on the R2 OTG port, which cable would i use? I cannot find any MicroUSB male to MicroUSB male cable anywhere.
With the added second USB connector, the two holes to fix the board are gone. How do you expect to secure the board? Is there any area of the board where holes can be drilled to fix the board without damaging it?
Thanks
I know that page, however none of my questions is being answered there.
