I hope someone can help. I am suddenly unable to load sketches to my ESP8266 Huzzah breakout board. I have at least 7 of these devices working throughout the house, programmed with the same Surface Pro I've been using. (Windows 10). I've installed the new Arduino IDE hoping it would fix the issue but it did not. Might be something simple, but I have not been able to resolve. Thanks in advance for any help someone can provide.
So I copied that URL to the Preferences Additional Boards Manager URLs: That now seems to be ok.

I uploaded blink just to test and its not loading. Seems to end without error, but the sketch is not running... I loaded standard, then changed the delays to 250. Just to be sure. The blue light dimly flashes. Highly unlikely....but I wonder if the ESP is bad?. Arduino IDE is 1.8.10 Sorry, one last thing, the devices is Adafruit Huzzah breakout. I buy those instead of the feather because I don;t need the USB as the interface.

it doesn't blink after pulling io 0 HIGH and reset?
No, Sketch not loading. I added serial.begin, and a simple message. And that is not showing on the serial monitor. The Arduino IDE used to show progress loading the Sketch in segments. Its as if the ESPtool.py is not bypassing the IDE progress I used to see and does the new sequence. When I read about ESPtool it looks like its for the Arduino board with ESP WiFi. I dont have that. I have the Adafruit board. How do I get rid of the ESPtool, the python utility. I think that might be the issue.

in 2.5.1 esp8266 Arduino boards package the esptool-ck was replaced by esptool.py. the same esptool.py which was always used to flash the esp8266 without the Arduino IDE
This is what I see when it compiles and loads. It seems to work. Couple other observations...
The red light for prg mode lights but is somewhat dim. I think when I've seen that in the past it is not actually in the prg mode. But I am not sure now.
When the sketch is loading, the blue light used to flash quickly. Now it does not. It flashes maybe once every second, but very dimly.
Again, there do not seem to be any errors below, but the sketch does not seem to be loading.
