| eduardas | hello, what is the state of 4G modem support in AGL at the moment? | 13:42 |
| dl9pf | eduardas: there is support for few modem types, see the telematics profile docs. iirc libqmi based. | 14:00 |
| dl9pf | @smurray do you remember the codenames ? | 14:00 |
| eduardas | dl9pf: why is libqmi used? ofono has its own qmi backend IIRC | 14:02 |
| smurray | ofono uses libqmi | 14:02 |
| eduardas | smurray: you use upstream ofono or fork it like Sailfish OS does? | 14:02 |
| smurray | eduardas: it's upstream only | 14:03 |
| smurray | eduardas: it's demoware, vendors wouldn't use this stack in product, likely | 14:03 |
| smurray | eduardas: ah, I am misremembering, we're not currently using separate libqmi | 14:04 |
| smurray | eduardas: but some libqmi bits are used | 14:04 |
| smurray | eduardas: outside of ofono | 14:04 |
| smurray | been 18 months since I seriously looked at it | 14:05 |
| eduardas | smurray: that is probably the case as libqmi is not listed among ofono DEPENDS | 14:05 |
| smurray | right | 14:05 |
| eduardas | smurray: http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-connectivity/ofono/ofono_1.31.bb?h=master | 14:05 |
| smurray | I'd have to dig around, we were tweaking it at one point to get support for a particular modem to work, but that's been dropped in icefish up | 14:06 |
| eduardas | smurray: those libqmi bits outside are critical for cellular connectivity or is it just some testing code? | 14:06 |
| smurray | eduardas: I can't remember right off. I do recall the tools were very useful for debugging why things were not working | 14:08 |
| dl9pf | i can't remember the modem board numbers | 14:08 |
| eduardas | smurray: I am currently doing an embedded Linux Yocto based project with cellular... if anyone knows a good developer for modem integration into the connman + ofono stack, it would be good to know | 14:08 |
| smurray | dl9pf: Sierra Wireless discontinued the ones we were using | 14:08 |
| eduardas | smurray: would also be good opportunity to cooperate as I can probably get AGL quite easily on our platform too | 14:09 |
| smurray | eduardas: the difficulty would depend on the modem, basically. Matt Ranostay that works with us did some work to get a couple working with ofono that weren't, but once you get away from Qualcomm ones, it's easy to end up with something with no upstream support | 14:10 |
| smurray | eduardas: we've had customers pick Sierra Wireless ones, they're more expensive but their Qualcomm module based ones do seem the easiest to make work | 14:11 |
| eduardas | smurray: I'm currently using Simtech SIM7500E via ofono's QMI backend, but with no modem-specific plugin which is probably not the right way to go about this | 14:11 |
| smurray | let me see if I can find the slides from ALS | 14:11 |
| eduardas | not competent enough to write the plugin myself | 14:11 |
| eduardas | smurray: I am actually following ELCE, ELC videos quite intensely, AGL included... however cellular on Linux is a very rare topic sadly | 14:12 |
| smurray | eduardas: yep | 14:13 |
| smurray | eduardas: here's our presentation from last year: https://tinyurl.com/y9v48d9u | 14:13 |
| smurray | eduardas: Digikey has been spamming Matt and myself about the SW modules being discontinued; I assume there are new models, but haven't looked | 14:14 |
| smurray | eduardas: both Matt and myself have dug around in the ofono code some (he more than myself), but we've not done a new plugin | 14:15 |
| *** bn_mobile has quit IRC | 14:19 | |
| smurray | eduardas: it occurs to me that Matt mentioned that Simtech module at one point, I'll ping him to see if he bought one to experiment with | 14:24 |

| eduardas | smurray: is there a plan to have a reference platform with 4G support? if so, how is this decided uppon? | 14:56 |
| smurray | eduardas: so far the AGL members haven't indicated a desire for one. They all have their own different criteria for modem selection for product, so getting consensus would be hard | 14:58 |
| smurray | eduardas: and there have been issues where some hardware they'd use for automotive isn't really purchasable for use in small quantities like dev boards | 14:59 |
| smurray | eduardas: that's definitely the case for radio tuners, I could see it being the same for modems, maybe | 15:00 |
| eduardas | smurray: does AGL care for NXP i.MX in any capacity? | 15:00 |
| smurray | eduardas: they're a member, but prefer customers directly engage with them AFAIK (they have their own AGL fork(s)) | 15:01 |
| smurray | eduardas: there's some community support for some i.MX6 and i.MX8 boards that uses what's available in the meta-freescale OE layer | 15:02 |
| eduardas | smurray: oh, that's interesting... perhaps I should try getting support from them, though I suspect they do not focus on 4G in any capacity | 15:02 |
| eduardas | smurray: did the decision to use connman + ofono in some way influenced by Tizen stuff? or did you have a serious discussion of NetworkManager/Modemmanager vs ConnMan/oFono? | 15:06 |
| eduardas | I think NetworkManager + ofono is also possible IIRC | 15:06 |
| smurray | eduardas: connman + ofono is the default in OE/Yocto, but I believe that does stem from the Intel folks who worked on Tizen/Moblin/etc. pushing it in as a lightweight solution | 15:08 |
| smurray | eduardas: iirc, Matt looked at the NetworkManager + ofono patches, and it looked like it'd take some work to get them going with current releases | 15:09 |
| smurray | eduardas: it's not something that works out of the box | 15:10 |
| smurray | eduardas: we kind of concluded hacking support for a particular modem in modemmanager would be easier if NetworkManager was needed | 15:10 |
| eduardas | smurray: good to know | 15:12 |
| eduardas | smurray: I am really thankful for you being generous with your time and answering my questions | 15:12 |
| eduardas | smurray: this is useful information for me | 15:12 |
| smurray | eduardas: no worries, good luck | 15:13 |
| eduardas | have a good day then, work hours have been over for me for a while now | 15:13 |
