Does Spacebridge work properly for anyone?

[alxjsn]

I have tried using an E303 and Nova R410 modem and when there is no activity over Spacebridge I stop being able to communicate with my device. It’s as if the modem becomes idle and doesn’t accept any inbound connections until I initiate network traffic from the device to wake it up.

Support has not been helpful either since they said that my modem might have a limitation and I would need to send a ping every once in a while. The alternative they recommended was to purchase a Nova, so I just got the R410 and I now I am in the same position as before.

The only thing I have been able to do is force my E303 modem to only use 2G: Keeping pppd connection alive? - #7 by alxjsn

No documentation talks about any limitations of modems going into an idle mode or how we are suppose use Spacebridge without losing connectivity. Am I just doing something wrong? I would just like to hear from someone who has actually had no issues using Spacebridge.

It also looks like there are a lot of people having issues with Spacebridge and there is never a clear conclusion/response to the issues. Here are a few examples of these threads:

Huawei E353 & SSH

Hey Guys, We’re using an E353. We have a good connection to your network and can reach the outside world. Great… but how can we ssh into the device. ifconfig shows only the local IP from your network and we need to be able to login the the device. rock

Keeping PPP connection alive while Tunneling without SpaceBridge

So I’ve just followed the instructions here: https://hologram.io/docs/guide/cloud/spacebridge-tunnel/#tunneling-without-the-spacebridge-client And managed to get a connection going. I am connecting to a Pi 3B+ with the NovaM (NB-IoT turned off), from a Windows 10 machine. The Pi is also connected on a wifi network, running headless. I am able to SSH into the Pi using PuTTy on the wifi (using the Pi’s local IP address on port 22), and then sign in and start the PPP connection using sudo holog…

Keeping pppd connection alive?

Hi! I followed the tutorial on the documentation with the Huawei E303 modem— everything works great, I can stand up a new connection, hit the internet, and tunnel back with spacebridge. (I’m using the stock configs from your documentation for pppd) The problem is that the connection seems to go idle after about 15 seconds of non-use. So, if I try to connect with spacebridge, it basically sits waiting until it times out OR I do something on the device to re-establish the connection, like ping o…

spacebridge tunneling down?

For the last 12 or so hours I’ve been unable to tunnel into my device. I can get out, but not in. No changes, just stopped working. Restarted ppp, nothing. Nova, RPI3, ppp Thanks.

Problems connecting to our devices via Hologram

Hello, We are trying to connect via SpaceBridge / tunnel our devices (we have three prototypes with SIM cards and hologram modems) but it throw us an error like this: ssh: connect to host tunnel.hologram.io port 999: Connection refused. It happens suddenly, 1 hour ago, it was working without problems but now we can not connect to any device

Additional notes about my situation:

• My device is running a small HTTP API and that is what I am accessing over Spacebridge.

• I am setting up my PPP daemon using the files from here: hologram-tools/ppp at master · hologram-io/hologram-tools · GitHub

• I have also tried using the hologram CLI directly and also get the same issues.
