LTE MC7710

Hi all.

I am trying to run MC7710 LTE card at RB411UAHR.
At 5.15 router os i cant do scan.
It shows info that modem did not respond.

I have tried 6.0beta2 instead.
Beta worked fine untill i plugged in modem at mpcie.
After power on, all interfaces has gone.
Only way to get in is by COM port.

Help :slight_smile:

Please use v5.15 for this modem.
You used winbox or webfig for the scan option. We have seen some posts on the internet that they say that scan isn’t working on those cards when they are in the lte mode.
Please downgrade to v5.15, enable async,debug logging and make a support output file when you are testing that LTE card. Then send us that file to support@mikrotik.com
Also send us the info commands printout so we could check the firmware version that you use.

I have done downgrade.
But still modem is not workik as it shooud.
I’m sending support file to you. Thanks.

I have made it running after modem firmware upgrade but only in 3G mode.
But modem can not scan for networks at all.
Desspite the fact that operator declares that LTE can work,
LTE mode does not connects to the network at all.

There is obviously more than one thing going on. Judging by recent developments in the linux kernel,
the MC7710 supports different interface communication types. The old was QMI and the new one is called MBIM.

We got many MC7710 working great in our Routerboards 411UAHR,
but the recent batch of MC7710s is not working.

I assume the firmware on the module does interfere, so,
possible the old ones had QMI and the new ones speak MBIM.
I have no way of further debugging but turning on async in logging on the Mikrotik boards.
This just tells me, the module is not responding at all.

Sadly there is no public firmware release for those Sierra Wireless cards,
so thats also a dead end. Also I couldn´t find any documentation if it is possible to switch from one standard to another.

I hope as the linux kernel dev goes on, also Mikrotik will implement both interfaces and everything works like a charm soonish :slight_smile:

Hello,

I received a new batch of MC7710, which have newer firmware (SWI9200X_03.05.19.04) than in the past. These seem really do not work on RB411.

The problem seem to be in the modem boot procedures or somewhere there. The modem works, if you are able to power it up AFTER the OS is running. You can test this with RouterOS x86 / laptop with wireless power switch, or if you have minipci-e => USB adapter.

The problem is not even Linux problem. On the Windows laptop I have Anite Outdoor analyzer software, which uses also Qualcomm diagnostics port connection. The analyzer cannot start/connect to the modem after power up, unless I let Win to boot and only then put the wireless on or flip to wireless on-off-on when windows is running. This setup uses normal Sierra Wireless Watcher & USB drivers.

Anyway the normal Windows connection with the watcher (or Win7 embedded mobile broadband) seem to work though!!

btw. just joined this forum, but the topic is well known. I was the guy getting Uldis&co to port MC7710 drivers to RouterOs quite a while ago.

Hi all,

Where did you find the firmware and tools?

I have an older MC7710 with firmware SWI9200X_03.00.08.02AP that works as expected with ROS 5.22, 5.25, 6.0rc13 and 6.0rc14.
Now just ordered a new one, but it does not respond at all, can’t event get the firmware version.

Any clues are appreciated.

Ahto

well, sadly there is no way to get the firmware directly from Sierra Wireless without having a contract with them.
So the only chance you have is asking the people you bought the modules from, to look into getting you a more recent firmware.
