The Hologram Nova is a cellular modem purpose-built for IoT development with single board computer compatibility and Hologram software tools.
This guide will walk you through setting up the R404 Nova. Once you plug the device into a Linux machine, you will probably need to enumerate it. The R404 has a Qualcomm chipset which can have inconsistent enumeration. To manually enumerate the Nova use the following commands:
sudo modprobe option
lsmod | grep option
You should get the following response:
option 32845 0
usb_wwan 9483 1 option
usbserial 29943 2 option,usb_wwan
Next enter
sudo sh -c 'echo -n 05c6 90b2 /sys/bus/usb-serial/drivers/option1/new_id'
ls /dev/ttyUSB*
This should result in you getting the following message:
/dev/ttyUSB0 /dev/ttyUSB2 /dev/ttyUSB3
If your LEDs are working you can skip the following three commands
screen /dev/ttyUSB2
at+ugpioc=23,10
at+ugpioc=16,2
Exit the screen session using 'Control+a' followed by 'Shift+k' and finally hitting 'y'
You should now be able to use our Hologram SDK and CLI.
Specifically,
curl -L hologram.io/python-install | bash
sudo hologram network connect
Alternatively, you can also open up a terminal to the new COM ports and type in AT commands directly.
Note: The Hologram Nova is no longer in production.
