The correction works. Now we got the PID value.

Wed Mar  8 10:15:25 2023 user.info LTEmodem: Waiting for ethernet adapter name
Wed Mar  8 10:15:26 2023 user.info LTEmodem: Waiting for ethernet adapter name
Wed Mar  8 10:15:27 2023 user.info LTEmodem: Waiting for ethernet adapter name
Wed Mar  8 10:15:28 2023 user.info LTEmodem: Waiting for ethernet adapter name
Wed Mar  8 10:15:29 2023 user.info LTEmodem: Waiting for ethernet adapter name
Wed Mar  8 10:15:30 2023 user.info LTEmodem: Release DHCP lease, PID: 4161

Maybe there is a better way to find out the process id, but I don´t know right now.
Of course , you can specify the ethAdapter manually, but I tried to make the script more generic.

Okay. I'll test the final config, and reply.

yodee13 · March 12, 2023, 7:47am

I think, we can mark this project succeded. There was more sucesessfully reconnect, reboot and all of these without fail. Thank you very much!

other thing: on these config, can You help me with GPIO?

frollic · March 12, 2023, 8:08am

Document the changes required?

Might want to create a new thread about the gpio.

yodee13 · March 12, 2023, 8:16am

Later I will attach all of the files and changes what is needed for working configuration.

mrhaav · March 12, 2023, 9:07am

Nice to hear!

I agree with @frollic, create a new thread.

In this, there are some important for me. I don't know exactly what packages are needed for the Mikrotik R11e LTE6 modem, but with this package list it is working. Beside that I use wireguard, DynDNS and many more extra. The interface called 'WANN' is a DHCP client and the config files are this:

Can I get signal strenght and other infos from the modem like this?

https://forum.openwrt.org/t/luci-app-luci-app-3ginfo-3ginfo-gui-info-about-3g-lte-connection/67893

yodee13 · March 14, 2023, 5:52pm

I've tested it with fresh build with firmware selector. Everything is works, no problem. I think we can close the thread.

yodee13 · March 14, 2023, 7:33pm

Just one thing! After fresh install, i restored the settings, and the mikrotikR11 service is disabled default. How can I set it enabled by default?

mrhaav · March 14, 2023, 8:13pm

But, isn´t that a one time thing to fix, or did I miss understood you?

yodee13 · March 14, 2023, 10:20pm

I think, i found something . If i backup the /etc/rc.d/, then i can restore the service.

Edit:

I tested it and works! I need to backup /etc/rc.d/

Sadly I have to find out the exact solution: too much irrelevant package was installed and the /etc/gcom/ncm.json file was also modified.

frollic · March 24, 2023, 2:07pm

then post your installed packages, and the diff for ncm.json
something is still better than nothing.

xabolcs · March 24, 2023, 2:13pm

I hope I could do it in the weekend!

Interestingly the proto '3g' mode is far more stable than the proto 'ncm': the ncm proto needs lot of love.

xabolcs · March 25, 2023, 5:28pm

I opened a pull request to use such a simple configuration.

In this pull request I publish my composition of all the information I collected… about Mikrotik R11e-LTE6 modem: * [Adding support for MikroTik hAP ac3 LTE6 kit (D53GR_5HacD2HnD)](https://forum.openwrt.org/t/adding-support-for-mikrotik-hap-ac3-lte6-kit-d53gr-5hacd2hnd/137555/) * [OpenWrt X86_64 + Mikrotik R11e-LTE6](https://forum.openwrt.org/t/openwrt-x86-64-mikrotik-r11e-lte6/151743/44) This modem has two quirks: * it writes a few message at startup which confuses the manufacturer detection algorithm * the `delay` option is a workaround * it boots into flight mode, so the first step should be to disable flight mode ---- Notes: I developed this PR with my hands on the modem borrowed from forum member **yodee13** (owner of the second thread). Now I sent the modem back.

PR landed with commit 91eca7b04ff1 and dbd6ebd6d84b!
The backport PR #12275 landed too! It will be included first in OpenWrt 22.03.4!

Using on SNAPSHOT builds and on OpenWrt 22.03.4+ releases

For `option proto '3g'`

# after opkg update
opkg install comgt kmod-usb-acm

Example configuration:

config interface 'mikrotik'
	option proto '3g'
	option apn 'internet'
	option device '/dev/ttyACM0'

For `option proto 'ncm'`

# after opkg update
opkg install comgt-ncm kmod-usb-acm kmod-usb-net-rndis

Example configuration:

config interface 'mikrotik'
	option proto 'ncm'
	option apn 'internet'
	option device '/dev/ttyACM0'
	option delay '20'

To ensure internet connecivity, ncm users may have exercise pingcheck's offline script.

Using on OpenWrt 22.03.3 and earlier 22.03.x releases

After installing the required packages one should grab the files from the PR:

save to /lib/netifd/proto/3g.sh on the device
save to /etc/gcom/ncm.json on the device

For option proto '3g' one should grab the runcommand.gcom file too (and put to /etc/gcom directory).

dchard · March 26, 2023, 8:51am

Looks good to me.

FYI, I tried to force the modem the QMI mode but that is not supported on this MikroTik modified Marvell crap, so PPP or MBIM (NCM) are the two options. For speed you definitely need the MBIM interface.

yodee13 · March 31, 2023, 5:03am

It looks fine. But the interface lease time is only 7200 s. How should we extend it?
