Hi Ana, There are quite a few things that catch my eye here. First there are many AT cmds that need to be updated for this specific modem, many proprietary AT cmds have changed. Still the SWWAN connection interface is pretty basic and as-is I think it should be able to work. It'd be great if you could verify your connection settings(APN) to start with, as I'm seeing a mismatch in information. The first log you gave shows 'internet' being used for the APN during your connection attempt, while the second log show's 'surfo2', but your actually registering to a home network on the E-Plus carrier. Online searches on my end show settings for that carrier more like, but please confirm with your carrier: <apn carrier="E-Plus Internet" carrier_id = "1453" mcc="262" mnc="03" apn=" internet.eplus.de" user="eplus" password="internet" authtype="1" type="default,supl" /> > > With this command, connecting the modem to a different device > (ModemManager version 1.6.4-1 and different hardware, USB 2.0), the > modem connects normally.
The different versions use different connection methods, the SWWAN interface (added in 1.8) is to support LTE bandwidth data transfers. Since this modem is a CAT1 device though, ie more limited LTE bandwidth, it might be okay to use the generic Cinterion setup with ppp. Before attempting an out of band patch to force that it'd be great to: 1. Get logs of 1.6 where the connection attempt works 2. Verify the connection settings above Cheers On Tue, Jan 29, 2019 at 5:39 AM Ana Rodriguez Lopez < rodrilopez....@gmail.com> wrote: > Hi Matthew, > > I attached to this email a longer log.
