I have a mangOH board with primary and secondary wp modules inserted. I’ve configured the resistors according to the mangoh user guide to route the second sim slot to the secondary module.
But how can I control the secondary module with legato ? If I save the apn details for the secondary to a new profile, for instance, I can’t use the cm tool to start a data connection with that profile. But can I do it programmatically via the legato modem service, and how ? Is it even possible to associate a data profile with a secondary module, then use the modem Service api with that profile ?
And, on the mangOH, the secondary is connected to the primary via the on-board usb hub, but the secondary doesn’t get an address from dhcp so what exactly is the point of that usb connection and how is it used ? Is it via AT commands ?
Update: ok, so I detect it as a usb device, dmesg says its a Sierra modem and it gets a tty port, but how then to configure it, eg set the apn or change network options ? This would require some kind of driver on the primary surely ?
Is there an equivalent of qmi-network.conf or a way to send AT commands to the secondary module ?
