I want to OTA my Mega 2560.
The first try was using an ESP-32 Dev Kit C V2 to connect to my WiFi, which worked fine, but the ESP32 refuses to upload and flash the SerialWiFiOTA sketch via IP address onto the Mega 2560 mostly. It seems to be that it is related to the current firmware’s fault (AT_Bin_V2.2.0.0) in passiv mode. Details can be found here:
https://forum.arduino.cc/t/wifiespat-serialwifiota-for-mega2560-via-esp32/940386
Currently I try the same thing, but using an ESP8266 NodeMCU v3 instead of the ESP-32 Dev Kit C V2. MY PROBLEM now: I can’t get the IP address of the ESP to choose in Arduino IDE. The fake programmer described by Juraj Andrassy doesn’t work either.
Here is the documentation on what happened so far:
Flash ESP8266 NodeMCU with AT 1.7.5
- Used „CombineBin“
- Flashed combined bin with “NodeMCU PyFlasher,” version 5.0.0 (115200 Baut, DIO)
