I am having some issues with getting the Hologram Nova to function after a system reboot. I am using the Hologram Nova U201 with a Raspberry Pi 4 with a 3A power supply.
When I plug the device into the Pi after it has been booted, everything works fine. Running
sudo hologram network connect works and brings up ppp0, and I see U-Blox AG LISA-U2 after running
If I reboot the pi, either by running
sudo reboot or by physically power cycling the device, running
sudo hologram network connect returns
ERROR: Modem not detected and it also the usb device doesn’t come up after running
Unplugging and replugging the Nova into the Pi will correct the error, and everything will come up.
I am searching into methods to cycle the power on the usb port or refresh it in some way, but haven’t had much luck on this front yet.
Any help here would be much appreciated. I have done extensive searching online and most of the time these issues come down to a power problem, but with the power supply I am using I just think that isn’t the case, especially since it works every time after I unplug and replug the device.
