If I catch all exceptions, how can I see what exception was raised?

I know that it's normally considered bad practise to catch all, but I would like to log the exception to somewhere (network or lcd) and not just freeze.

Data should be localized in UI. If you have a "dumb" sensornode then it should report values in machine readable format. If it has a user interface then it should localize data.

I consider mcu's more suitable for dumb sensor nodes, but I'm no expert on them.

It should be relatively easy to tell, if someone is connected, by calling uos.dupterm(). That's what webrepl does. If someone is connected, it will return True. That assume showever, that the only two possible REPL connections are USB and webrepl. Update: Just tested that. On REPL, not not uos.dupt...

That's similar how I currently do it. But it does requires to physically go to the sensor, which I would very much like to avoid:)

Can I somehow know in my script when someone is connected via webrepl? My use case is a sensor node that measures and then deep sleeps for a minute, and repeats. I would like to check if someone has connected via webrepl before the node goes to deep sleeps and if there is a connection then stop and ...
