Hi,
I have a similar (or maybe the same) problem. Using the chrome plugin under Linux I cannot connect to the device. Console shows:

>>> Connecting...
ForceThrottle option is set - set Slow Write = true
[object Object]
Connected [object Object]
ERROR: RECEIVE ERROR: {"connectionId":1,"error":"device_lost"}­
Disconnect callback...
WARNING: [notify_warn] Disconnected
>>> Disconnected
ERROR: executeExpression called when not connected!

Same happens without throttling. If I just use the ESPTool, I can connect without any problems (115200 baud as well) and execute code on it.

Is there maybe at least a way to get more information about what causes the "device_lost"?
