Hello, I recently bought Hologram Nova 3G/2G Cellular IoT USB modem (Sara-U201), attached data module with SIM card to Raspberry Pi 3+, activated the SIM card, used CLI to send SMS and data messages to cloudsocket.hologram.io and it works with Raspberry WiFi tuned on. It doesn’t send data messages with WiFi turned off. Response message says “can’t resolve cloudsocket.hologram.io” which makes sense as there is not internet connection.
How should I tell Raspberry to use USB modem (Sara-U201) as internet gateway ?
Trying to apply your experience with what I’m trying to do…, basically the same thing with the SARA-R410M.
So by simply issuing the “sudo hologram network connect” command, does “iwconfig” reflect a fully functional ppp0 or usb0 port? My system certainly does not.
Yeah iwconfig won’t work because it doesn’t consider it to be a real wireless interface like wifi. Try ifconfig when you can. You should see ppp0 on there with an IP address.
