So recently I tried to bring back my previous setup back to live. sh*t happens..

The blue LED seemed to be on constantly and nothing seemed to work.
I checked all the stuffs, and previous set up worked fine but this time isnt...

Anyway i took a short video to show u what happened.

It's my personal blog, so u can check it out. the issue is inside.

i just noticed that. it seems to be on when you don't use Serial comms. i removed all my Serial.println() calls to reduce the memory footprint and noticed that the blue led stays on all the time.

you should be able to turn it off manually with digitalWrite(1, LOW);

Nope. digitalWrite(1, HIGH) does not turn it on. Nor does any other pin. For me it seems to come on when something bad is going on and all hell is breaking lose. Unfortunately, I have not yet figured it out.

Meant to say that digitalWrite() does not turn it off either.
