Hi all, I am building an application that will maintain a wifi connection and a cellular connection via the Nova R410M. I have two issues that I believe are due to the boot configuration and the ip routing.
First on how the booting is setup:
I am establishing the wlan connection using wpa_supplicant on boot and running hologram network connect using systemd
`debian@beaglebone:/etc$ cat /etc/systemd/system/holConn.service
Description=Connect Hologram Service
ExecStart=/usr/local/bin/hologram network connect
There was a periodic issue where the serial port was unable to be reached so the ppp connection failed. I believe I was able to overcome this by adding
nodefaultroute to /etc/ppp/options. This was in hopes to prevent the wlan connection from competing with the ppp connection at boot. This has appeared to work, but I was hoping someone with some experience with this can shed light onto if my suspicion was correct.
The current issue has to do with having two gateway connections. I run into an issue where the wlan connection becomes dormant and the ppp connection becomes the default gateway. In this configuration the system is unable to reach the internet at all. I am working on understanding building the routing tables for each connection and the associated rules to ensure that the wlan connection is the default gateway, and the ppp connection is simply available if wlan fails or if I need to tunnel into the device in the field.
Has anyone had experience with either of these issues? Any help on how I might maintain this multi home configuration will be helpful.
Thanks in advance!
