expected START_HEADER0 0xfe, got nothing

Hi

So I took the plunge, and bought a GEM WIFI. I've been tinkering with it a bit.

I'm trying to get btmon.py working. The GEM is in I guess "monitor" mode ---

btmon.py connects but gets this. Any idea:

^Csean@X~/p % ./btmon.py --ip-mode=client --ip --ip-host=X--print -p-port=80 --device-type=gem
2014/07/04 22:35:46 btmon: 3.0.7

2014/07/04 22:39:17 expected START_HEADER0 0xfe, got nothing

And thats it. Any ideas?

Did you really do "-p-port=80" or is that a typo? Should be --ip-port (with 2 leading dashes)

Is the gem in "real-time" mode or not? I think you need it to be if you want btmon to act as the client.

As for the port, I can't tell from the docs how to set the port that it broadcasts on in realtime mode, and I don't have a gem, sorry. but http://lancet.mit.edu/mwall/projects/po ... config-gem shows an example of --ip-port=5000 - so I guess that's settable somewhere in the gem config. I'm guessing 80 isn't correct, but I'm just guessing, sorry.

Did you happen to enter Setup Mode on the GEM and not exit after? It can take up to 5 minutes for it to start sending packets again if you don't click the "Exit Setup Mode" button.

Using the GEM Network Utility, can you attach a screenshot of your WiFi setup?
