Adafruit IO Data Uploads - Red LED error light activated (Enviro Weather and Enviro Grow) about enviro

I think that the responses to issue #77 may assist you understanding the red LED. Essentially it's telling you that the upload failed for one reason or another, let it try again and it may go, and that it will be continuing to try whilst it is on.

To get back into the board once it's gone red, connect it, hit the reset button on the back, wait for it to cycle and then press stop within Thonny. That should get you back in.

@MrDrem, I'm not sure what you are doing differently to me, but I've tried 50+ times (over multiple days) to access the board via Thonny once the red LED has been activated, and I've not been able to connect once. (connect via USB, use the reset button.) The only way I've been able to gain access to the board is by putting a fresh version of the firmware onto the board thereby wiping out the upload files.

I'm close to the point of ditching the official firmware and writing my own scripts.
