Hey,
is there any way to increase the speed of recognition of the LTE-Modem?
It takes a while to connect and I wondered if maybe there is a faster way?

@Arrowtec Can you explain your use case a little more? Are you referring to the time it takes to get the initial Internet connection up or are you also including the time to connect to a VPN?

I am just referring to the time it takes for the modem to connect / the network interface to show up having a working connection.

@Arrowtec The issue is that the modem is held in reset until the Voxl software pulls it out of reset. Once it has been pulled out of reset it has to boot up and initialize it's interfaces before it is ready to set up a connection. So, it is important to start the process as early as possible in the startup sequence. Are you using a systemd service file to start your modem connection?

@Eric-Katzfey I figured that would be the case. Atm I am just letting it boot on it's own; the systemd service file is an idea that i will test and afterwards I will get back to you.
