WiFi does not start after firmware upgrade
Hello to all!
There is a problem with the NodeMCU v.1.0 board. I tried to flash versions: ESP_Easy_mega-20181117_dev_ESP8266_4096, ESP_Easy_mega-20181117_normal_core_241_ESP8266_4096, as well as versions 20190301, 20190311. For loading, I used ESP.Easy.Flasher and Nodemcu-flasher. After the reboot, the serial port displays the following: [attachment = 0] screen.jpg [/ attachment], however, the access point "ESP_Easy_0" is not created. After entering the serial port commands WifiSSID ..., WifiKey ..., Save, the module responds "OK", but after reboot it does not connect to the router. If you flash other sketches through ArduinoIDE, everything works fine, the AP is created, it connects to the router. What could be the reason?

Re: WiFi does not start after firmware upgrade
Old settings are still in use, try to do a clean (blank) flash before the real flash.

I was flashing blank_4MB.bin before each update.

Re: WiFi does not start after firmware upgrade
I thought that the board was faulty, but I tried to download many different sketches through the Arduino IDE - everything works fine, both in AP mode and in STA mode. Unfortunately, I can not compile ESP Easy via Arduino IDE v.1.8.7 - it gives a huge number of errors, I can not figure it out.

Why do you need to compile a custom build?

Re: WiFi does not start after firmware upgrade
No, I wanted to try flashing through the Arduino IDE, since other sketches are stitched normally.

Ok, if you have problems with that you should try our normal approach using the Flasher...
