Yes. Take care, however: ESP8266 apps starts with the same byte.
Re: Magic Byte bin file
Hi ,
So is it safe to use this byte as the start of the bin to detect the end of http headers for OTA update?

As long as you don't mind people also being able to accidentally chuck an esp8266 firmware image into the OTA thing, sure. If you want more verification, you can check components/bootloader_support/src/esp_image_format.c which does some validation of images in the bootloader.
