Embedded wireless modules

Hi, I want to use qmi_wwan and qmicli with WP76 module, but I saw the following that no response on QMI message. Any idea?

Hi @jyijyi,

I have reproduced your steps on my WP7601, this error does not happen.
log.txt (7.3 KB)

  1. Which WP76 device do you use?

If your device is not running on latest FW, please upgrade it latest firmware and try it again.

Thanks,

#3

Ok, i will try your fw.
May i know if you are using the default qmi_wwan driver in ubuntu?
If so, which ubuntu version are you using?

#4

Hi,

Does all WP series support qmicli?

#5

Hi @jyijyi,

I use Ubuntu 18.04.2 with Sierra Linux QMI Driver (https://source.sierrawireless.com/resources/airprime/software/usb-drivers-linux-qmi-software-s2,-d-,38n2,-d-,59/#sthash.QusgYo4o.dpbs), you can install this driver and try it again.

Thanks,

Hi @fashionshow0,

Currently, Sierra Wireless is selling WP series, include: WP7605, WP7607, WP7608, WP7609, WP7611, WP7702. All the devices support qmi mode.

If you have other issues/concerns, please create a new topic.

Thanks,

Hi @jerdung

The gobinet driver is for enumerating /dev/qcqmi0 port.
And qmicli is using /dev/cdc-wdm0, are you using generic qmi_wwan driver?

#8

@jyijyi

thanks, so the qmi-firmware-update is also supported?

#9

Hi @jyijyi,
I think your kernel lacks this patch:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/usb/qmi_wwan.c?id=97dc47a1308a3af46a09b1546cfb869f2e382a81
(“qmi_wwan: apply SET_DTR quirk to Sierra WP7607”).
