Easy flasher not finding USB COM port

#1 Post by bigegg » 10 Apr 2021, 00:39

I've spent a couple of hours on this, now...

(Win10)

I have a chinese eBay "nodeMCU" clone board: ESP8266, WIFI, .91" OLED built in.

I can upload the ssd1306 example sketch using arduino IDE - and it works fine (after changing the reset pin to -1)
I can "tasmotize" the board.

If I use "ESP.Easy.Flasher.exe", it will not find the USB port.

as I say the port is found and is used by tamsmotize and arduino IDE to upload to the board - It will find another ESP8266 connected using same (physical) port + same cable.

I have tried manually changing the port number of the USB port via devmanager - and all the front USB ports (I cant get to the rear without stripping out my desk)

FlashESP8266.eze DOES find the port but the upload fails on something else (I'm running it from within the "BIN" directory):

This is a known issue of the ESPEasy flasher as some 'funky' USB to serial chips do seem to register themselves in some strange places in the Windows registry, in places where ESPEasy flasher is not looking.

You can still use the included Espressif flasher. See: https://espeasy.readthedocs.io/en/lates ... g-software

Thanks for that!
I don't know why, but I thought that the espressif one was just for the ESP32 :oops:

Too late tonight, but I'll give it a try in the morning.

Thanks again1

Now working...
Bedside clock/calendar/temp gauge.
Reading time from pool.ntp.org, and temp/humidity via MQTT and wifi from an ESP32 in the garden.

Is there any way to stop the display powering down?
Or a quick pointer on how to power it back up - without having to reset?
