ATE0--> Send Flag error: #0 #0 #0 #0 AT+BLEINIT=0-->AT+BLEINIT=0

Hi, I opened this thread
http://forums.sifive.com/t/modifying-zephyr-bootflow-to-skip-esp32-at-commands/3368 to understand where this bootloader code resides. Could you give some pointers to it, either here or in the other thread?

Thanks in advance!
Anthony
