miki991 Posted September 26, 2020 Share Posted September 26, 2020 Hi! Did anybody try setting modem port to 6 or 8 as described here?: https://osxlatitude.com/forums/topic/8006-sierra-wireless-qmi-modules-mcem73xx77xx8805etc-dell-dw557058085809etc/ Quote For Legacy use, Modem port must be enabled in configurations modules: example, USBCOMP = 6, or 8 @influenist this script that you mentioned sets the card in MBIM only (+AT) mode. If Im not mistaken for OSX and this kext we need to put the card in the mode that supports QMI mode also? Quote - Sets MBIM Mode with AT Commands Access https://www.ttl.one/2018/07/sierra-wireless-lte-autoflashing-em74xx.html So for example on this page that was linked scripts github page (https://zukota.com/sierra-wireless-em7455-how-to-enable-com-ports/) the modem supports mode 6,8, and 9, and was set in mode 8 that doesn't support QMI Quote 8 - DM NMEA AT MBIM SUPPORTED But if we set modem (manually, without script) to modem config 6, that mode support QMI Quote 6 - DM NMEA AT QMI SUPPORTED Can anybody please check if this solves this issue so I can go order this card on Ali? instructions here: https://zukota.com/sierra-wireless-em7455-how-to-enable-com-ports/ Link to comment Share on other sites More sharing options...

influenist Posted December 1, 2020 Share Posted December 1, 2020 Hey @miki991 , I tried all sorts of combinations yet can't remember exactly though if I followed up your notes. Even made the kext working for the 3 variants. I'll retry this at some later stage as I'm too caught up with work / private life. Why not buy the card and help the community ?! Attached the latest version I could find in my backedup EFIs. Legacy_Sierra_QMI.kext.zip Link to comment Share on other sites More sharing options...

I tried to connect manually using AT commands and ATD*99***1# gives ERROR Link to comment Share on other sites More sharing options...
