setup_ap.sh logs error "unknow option 'i'"

See original GitHub issue

In the scripts/setup_ap.sh https://github.com/ct-Open-Source/tuya-convert/blob/2cf2fa59ca04838da89b0c9ac273c1c4227676d3/scripts/setup_ap.sh#L35 there is a call to hostapd where the wifi interface option is given by the -i parameter. I’m using Debian 9.9 and getting the error unknow option 'i'. For me a quick fix was to directly manipulate the scripts/hostapd.conf by providing the correct wifi interface on my machine.

# interface file to control hostapd from tuya-convert
ctrl_interface=hostapd_ctrl

# our AP SSID
ssid=vtrust-flash

# manually specify channel, as ACS may not work on some systems
channel=1

# set log level to info to cut down on noise
logger_stdout_level=4

# added this line
interface=wlan0

Here’s the output of my hostapd -h command:
