Hello,
I am using Elixir/Nerves for a IoT project on a RPi3 and wanted to use a Hologram Nova for general internet access (HTTP requests, websocket connection, etc.), I read about how a PPP session can be established through both the CLI and Python SDK. I have the Python SDK installed with Elixir/Nerves running on a RPi3, I have a custom python script (foo.py) that I am using to run the commands I found in the online Python SDK documentation with some debug output:
from Hologram.HologramCloud import HologramCloud
def hello(arg):
print "running python/foo.py, hello()"
hologram = HologramCloud(dict(), network='cellular')
print "initialized"
result = hologram._networkManager.listAvailableInterfaces()
print "network manager interfaces: %s" % str(result)
result = hologram.network.connect()
print "network connect: %s" % str(result)
print "localIPAddress: %s" % str(hologram.network.modem.localIPAddress)
print "remoteIPAddress: %s" % str(hologram.network.modem.remoteIPAddress)
print "signal_strength: %s" % str(hologram.network.modem.signal_strength)
print "imsi: %s" % str(hologram.network.modem.imsi)
print "iccid: %s" % str(hologram.network.modem.iccid)
print "operator: %s" % str(hologram.network.modem.operator)
return 1
The above script leads to this output:
running python/foo.py, hello()
initialized
network manager interfaces: ['ble', 'ethernet', 'wifi', 'cellular']
network connect: False
localIPAddress: None
remoteIPAddress: None
signal_strength: 21,99
imsi: [IMSI #]
iccid: [ICCID #]
operator: Verizon Wireless Hologram

The Nova plugged into my RPi3 has a solid red and solid blue light, I believe that indicates a successful powerup and connection? I see a operator but no local and remote IP. However as you can see from the output when I call hologram.network.connect() it is getting False. I have looked on the Forum but there isn’t much related to what I am seeing, I don’t see any errors or any other output that indicates what went wrong. Does anyone know what I can try? Or what could be going wrong when trying to establish the connection?
Thank you.
