I have several Nova Sara-U201 systems deployed and I only use the PPP connection for communication to my devices. The system works extremely well!! and has for a couple of years now. I am very happy with the Nova Sara-U201.
I decided to try the Nova Sara-U410 as I was unable to acquire any Nova Sara-U201’s.
The first problem I found was I was unable to successful connect to the network.
The error reported was PPP session failed.
Upon reading many message here in hopes to fix the problem I came across a very helpful tip. Issue reset to the modem.
sudo hologram modem reset
After that I was able to connect and actually get a PPP session started.
Once I had the device connected to the network with an open PPP section I used another computer to establish a space bridge tunnel connection.
After starting the space bridge tunnel I attempted to log into the device.
It took a long time maybe a minute or so before the login prompt show and about the same for the password prompt and then after enter the password a minute or more wait until the prompt.
Ultimately the connection is made however it is so slow it is completely unusable. It can take 10-15minutes between exchanges. Now the transmission rate is great very fast but the time between messages.
For me this makes the current Sara-U410 implementation not usable. I would really like to see it work so that we can move forward with the deployment of new cell networks.
Any help would be appreciated.
