Failed to connect to ESP8266: Timed out waiting for packet header (Sonoff iFan03)

[rubenkr]

Hi there,

just wanted to say thank you very much for making this code publicly available! May I ask for help flashing on following environment:

Device: Sonoff iFan03 DIY
Kernel: Linux arch200x 5.6.14-arch1-1 #1 SMP PREEMPT Wed, 20 May 2020 20:43:19 +0000 x86_64 GNU/Linux
Serial: Using FTDI

[ 2559.447673] usb 8-2: new full-speed USB device number 20 using uhci_hcd
[ 2560.075762] usb 8-2: New USB device found, idVendor=0403, idProduct=8a8a, bcdDevice= 6.00
[ 2560.075769] usb 8-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2560.075775] usb 8-2: Product: FT232R USB UART OPAS_UNIV
[ 2560.075779] usb 8-2: Manufacturer: FTDI
[ 2560.075783] usb 8-2: SerialNumber: A6PVTAWC

Tasmotizer proposes /dev/ttyS0 as Port which I followed. Before I set the rights to flash over it with sudo chmod a+rw /dev/ttyS0. Jumper Pins of FTDI are on 3.3V.

When bringing the Sonoff in Pairing Mode and trying to flash I get the following error:
Failed to connect to ESP8266: Timed out waiting for packet header

Could you please give me a hint? Thank you very much !

Broken FTDI Adapter. With another one it worked.
