OK, well, I have yet to receive any usable console output from the Mark IV, just like control chars and gibberish.
But clearly, that is output. Again, I have set to 115,200, 8-n-none.
I have been told that is correct, but at the moment I am at the point of re verifying that by trying different port speeds.
Unless someone can verify that port speed.
Sebkinne says it's dead, but clearly there are degrees to that because it clearly comes on wifi as pineapple. So dead, that's relative.
There should be a failsafe reflash method for these, that is used at the factory. Does anyone know about that?
