Yes it seems this GNSS implementation is different from the one provided by gobi. > Anyway, Tony, is there newer version of this patchset? It would be > good to get something in... Sorry it will likely be few more weeks before I can look at this stuff again. > Can I help somehow? I think I'm pretty clear on what needs to be done regarding this patchset. Probably taking a look at if we could implement a minimal raw /dev/gsmtty* read/write access in ofono using ell instead of gatchat would help most :) So something that mbim modem is already doing I think, sorry have not had a chance to look at that either. The /dev/gsmtty* devices should not change even with the further changes to this patchset. Regards, Tony
