1) dfu library in wifi link is it used whatever the way of uploading ? IDE, Python, Avrdude ?2) is there another version compatible with Mega2560 ?3) how can we upload a sketch by OTA into Mega2560 ?4) is it possible, easy, to modify the Mega bootloader to make it listen on both UART0 (cable case) and UART3 (wifi case) ?
Running it (way python + arduino_mcuota), i got an error.
So that is two reasons not to use GPIO 15. Is it possible to choose a different GPIO ? where is that defined ?
With my mega 2560 board, i use two shields with SPI. I must use pins like in an UNO board (11,12, 13 and SS). For the SD card, i set SD.begin(9,11,12,13). In the WiFiSpiESP usage, how can i make the same ?
