It seems your version of ModemManager is almost 2 years old. Is there a chance you can please update it?
Hi, that’s not correct. We are using v1.32.12 which was released in September 2021. A different thing is that the specific device type you are running has not yet been updated to the latest meta-balena. What device type are we speaking about?
Hello @jkridner could you please confirm us about the device type you would like to see a ModemManager update? Thanks 
Quectel E25 module

Hello @jkridner good to see you here in the forums again
What device are you using with the Quectel E25 module?
Thanks
Jason could you please confirm us the version of the balenaOS you are using?
Right now the beaglebone-black for example has the last final release at 2.85.16+rev1, so that has MM v1.18.4.
Let’s stay connected
Looks like I’m on 2.85.16+rev1.
I need to set some things up in the device tree and toggle some GPIOs to reset the modem at startup. I’m going to bite the bullet and start building my own OS images using Yocto. Once I get there, I’ll report back.
I may provide some patches upstream to avoid others needing to rebuild the OS just to:
- change the DTB (or add an overlay) or
- run some scripts to toggle GPIOs or other such tasks on startup
@jkridner keep us updated on this! And I’m following your other thread
Do you have any examples where a UART is used instead of a USB connection?
@mpous I’m stuck at a critical time. If I run BeagleBoard.org Debian, I can use shell-script/pppd/chat to enable the modem and make a cellular connection.
I’ve rebuilt the image using Yocto, but so far I’ve found it easier to manually edit the running image to change the device tree and add kernel modules than to make a new OS image. Eventually I’ll provide some updates for that.
I’ve fallen back to simply trying to add a whitelist UDEV rule to set the ID_MM_PLATFORM_DRIVER_PROBE flag
UDEV rule seems to be working:

I think I finally figured something out. There was magic implied that I should have considered a bit more…
I got the impression from the udev rules inside the container that some magic was going on to put those rules into the Host OS. This seems not to be the case and instead the event triggers are simply being based to the container and being accessed from within the container.
This means ModemManager won’t see the same udev environment in the HostOS that I see in the container.

All that talk about udev rules in the container sent me for a loop. I’ll work on manually copying them to the Host OS or put them inside config.json as some other folks have mentioned.
So close, yet so far…
Hacked in save udev rules into Host OS, rather than container, and surprise it actually probed.
I got here with ModemManager before, but I don’t know how to help it. I can give you the exact AT commands needed to establish a PPP connection, but this thing just wants to get in the way.
I think this was where I got to when I hoped a new version might help.

OK, seem to be getting to the other side of this. Hope someone will find all this useful.

Woot!
My install hack is nothing to copy, config.json looks like the right approach, but adding extra environment flags to my udev rules made a huge difference!

Hi Jason, just checking whether there are still loose ends we can help out with. Did adding the udev rules via config.json solve the problem?

I added the below to config.json seems to work for the udev rule, but I don’t have a way to update the device tree.
I need to fix the device tree to fix the pinmuxes. I think most people will need to fix the device tree for their applications. Is there a way I can do this on the images used to flash the boards?

@alexgg Seems I have 2 problems:
- I still need a way to update the device tree
- I need to run a script in the Host OS
Right now, I’m running the script to enable the modem within my application. I thought this was working, but instead it seems to be kicking the devices off the VPN. I’m guessing this is due to some kind of network race condition where the modem connection comes up after the local LAN and VPN, but I’m not sure.
OK, not sure why the VPN went down. I was able to get connected by updating my balena cli version and found out, despite what I added to config.js, I did not get any udev rules added to my system’s Host OS:
