Dear community,
I am new to the community so I will shortly introduce myself.
My name is Dirk and I am working as IT developer in a small team.
We are using Mikrotik's KNOT devices for several IoT projects.
We are encountering some issues with utilizing LTE-M and GPS on the KNOT devices.
We have tried configuring the devices both with the stable version of routerOS (6.48.3) as well as the development version (7.1beta6).
A demo video for the KNOT shows how to configure LTE-M on the device, using the PPP-out1 interface. Double clicking this interface in the interfaces list in Winbox opens a configuration menu. In the demo a port called ‘modem’ is selected. That is because the demo is using RouterOS 7.1 beta 7, which is not yet released. In the current versions, the correct port for LTE-M is called 'usb2', which is shared with GPS initialization and data.
When requesting cellular info for the PPP-out1 interface (by pressing 'info') a window is opened that shows some information. However, it returns error for 'Current Operator', 'Access Technology' and 'Signal Strength'. Perhaps this is common and it concerns info that cannot be retrieved. However, when closing the window and enabling the ‘ppp-out1 interface’, I am not able to successfully ping an address such as “8.8.8.8”. These attempts were done using several LTE-M sim cards and their corresponding APN’s. We have also made sure that the ppp-out1 interface is disabled when requesting the info, because this can not be done simultaneously.
As for GPS, we were informed that it uses channel 2 for initialization and channel 1 for data. So in our configuration we set 'init channel' to 2, and 'channel' to 1, and checked the 'enabled' checkbox. The GPS is now initialized, but it is not returning us any values except for 0.
I think we may be doing something wrong here, but find it hard to figure out what exactly.
Perhaps someone in the community has encountered this issue before and/or knows how to resolve it.
Any feedback would be greatly appreciated.
