Serial Protocol ESP32 => Download Mode UART
Analysis of dump esp32_after_boot_Keep_Boot_IO0_Pressed_win7_esptool_py_flash_id_OK.sr

See https://github.com/themadinventor/esptool/wiki/Serial-Protocol
The bootloader protocol uses SLIP framing.
Each packet begin and end with 0xC0, 
all occurrences of 0xC0 and 0xDB inside the packet are replaced with 0xDB 0xDC and 0xDB 0xDD, respectively.

Repeat Opcodes 0x08 Sync Frame each 300ms until we have an answer from ESP32 (until ESP32 is ready)
