Hi Denis, If we're going to get anywhere with this, the onus probably falls on you to do some cleanup work on these patches. I'll write some comments on the patches and maybe you can munge those into the commit messages...? Bing Jupiter has been running this modem (uBlox SARA R4) for well over a year with these patches so they are somewhat tested. That said, this modem isn't without issues, but it appears to me that those are mostly firmware related at this point. Yeah, not great advertising for the product; probably best to stay away from it altogether, really... /Jonas On 12/05/2021 09:40, Bing Jupiter wrote: > Cleaned up comments and resubmit > > Bing Jupiter (4): > Detect SARA R4 QMI device > Detect SARA R4 QMI device > Detect SARA R4 QMI device > Detect SARA R4 QMI device > > drivers/atmodem/vendor.h | 1 + > drivers/qmimodem/gprs.c | 10 ++++++++++ > plugins/gobi.c | 11 ++++++++++- > plugins/udevng.c | 42 ++++++++++++++++++++++++++++++++++++++++ > 4 files changed, 63 insertions(+), 1 deletion(-) >
