The script freezes there for

I use orange pi Plus 2 with armbian ubuntu 18.04. I already kill wpa_supplicant process. I also make sure that I did't open tuya app on my mobile devices. Homeassistant instance was also stopped
192.168.2.82 is IP address when my 3 gangs wifi switch connects to myWiFi network.
the orange pi box is on the same network of 192.168.2.82. I couldn't find dhcpd on my OS. Is that maybe issue? I also have my DHCP service on my router on 192.168.2.x network. Do I need to disable it or something?
When the script froze and stopped at that. The led on my 3 gangs wifi switch indicated that it is working with static green led. Flashing green led is connecting/searching wifi. Gang is turned on: red led, gang is turned off: blue led. Since the device is at static green led, I need to hold the button for 20 seconds to reset it, I then can add it to tuya app.

Thanks for help or let me know step to debug.

Can you run the script again and in a second terminal ping the device while the script is running?
You should see the pings stop after the following appears in the output.

Redirecting device 192.168.2.82 to use Access Point ZAGDU-789
**** Redirect appears successful

That would mean the device has been successfully redirected to the ZAGDU-789 access point and that the problem might be with the access point.
If that is the case then run the following without the script running:

hostapd hostapd.conf

Then try connecting to ZAGDU-789 with your phone. This will fail, but the output from the hostapd command will tell me something.
You should see something like this:

wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED 
wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: authenticated
wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: associated (aid 1)
wlan0: AP-STA-CONNECTED xx:xx:xx:xx:xx:xx
wlan0: STA xx:xx:xx:xx:xx:xx RADIUS: starting accounting session 07EB2952226E564D
wlan0: STA xx:xx:xx:xx:xx:xx WPA: pairwise key handshake completed (RSN)

You don't need to have DHCP or DNS servers running on the machine the script runs on because it has its own cut down DHCP server built in.

Thanks SynAckFin

I have just tried
root@orangepiplus: /TuyOTA# cat hostapd.conf
interface=wlan0
wpa=2
ssid=ZAGDU-789
wpa_passphrase=un49fqxc
hw_mode=g
channel=1
root@orangepiplus:~/TuyOTA# hostapd hostapd.conf
Configuration file: hostapd.conf

Using interface wlan0 with hwaddr 28:f3:66:b6:10:ce and ssid "ZAGDU-789"
wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED
wlan0: STA xx:xx:xx:xx:xx:xx IEEE 802.11: disassociated

Both of my phone can't connect to the ZP ZAGDU-789. It said incorrect password although I make sure that it is un49fqxc. Tried to change to password but it had the same result. I will recheck this.

[SynAckFin]

If you comment out the wpa=2 and wpa_passphrase=un49fqxc lines with a # then the access point wont require a password

[hungpr0]

Thanks. I tried to comment out those 2 lines but my phones still ask for password!. I tried to rename the SSID to make sure it using the current config file.
interface=wlan0
#wpa=2
ssid=ZAGDU-7890
#wpa_passphrase=un49fqxc
hw_mode=g
channel=3

Thanks. I tried to comment out those 2 lines but my phones still ask for password!. I tried to rename the SSID to make sure it using the current config file.
interface=wlan0
#wpa=2
ssid=ZAGDU-7890
#wpa_passphrase=un49fqxc
hw_mode=g
channel=3

I'm surprised at the phone asking for a password. Type in any password it should still connect to the access point and then fail to get an IP.

Same problem with default AP ARMBIAN armbian-config command line. Password is incorrect. Not sure if it is hardware issue or not...
