Can’t connect to vtrust-flash

[sominaik]

Hi,

I'm unable to connect to the AP from any other device. Pls help

[Mrnt]

Did look at the log files generated in the tuya-convert/scripts folder?

[sominaik]

No logs available in the folder. Do I have to initiate them?

[Mrnt]

What are you running this on: OS? python version? python virtual environment?

Did you see the following show up in the console?:

check_eula
check_config
check_port udp 53 "resolve DNS queries"
check_port udp 67 "offer DHCP leases"
check_port tcp 80 "answer HTTP requests"
check_port tcp 443 "answer HTTPS requests"
check_port udp 6666 "detect unencrypted Tuya firmware"
check_port udp 6667 "detect encrypted Tuya firmware"
check_port tcp 1883 "run MQTT"
check_port tcp 8886 "run MQTTS"
check_firewall
check_blacklist

I had trouble getting it to work on Debian Buster - even after installing all the dependencies it would just not do anything. It turned out that on my install the command "ping" required sudo so I had to modify start_flash.sh

changing
while ! ping -c 1 -W 1 -n "$GATEWAY" &> /dev/null; do
to
while ! sudo ping -c 1 -W 1 -n "$GATEWAY" &> /dev/null; do
and
while ! ping -c 1 -W 1 -n 10.42.42.42 &> /dev/null; do
to
while ! sudo ping -c 1 -W 1 -n 10.42.42.42 &> /dev/null; do

Thanks for your response. Following is my setup

1-Virtual machine using Virtual Box --
2- Ubuntu 16.04 installed as an OS
3- TP-LINK_Archer_T4UH is used as wifi dongle .. driver succesfully installed
4- Python installed on the ubuntu system is 2.7.12

when i start the flash, I can see normal output on the console. The problem is that i cannot connect to the wifi dongle from my phone or laptop. how to capture the logs?

[Mrnt]

Does the WiFi access point show up on your phone/laptop?

I think if you get as far as the access point starting then you should start getting some logs.

[sominaik]

Yes, I can actually see that and can click on it to connect
it just does not get connected

[Mrnt]

It is supposed to be using python 3 I think. Check you have that and then you may want to set a python virtual environment using python 3 if it is using python 2 by default.

[sominaik]

any guide would be helpful

[Mrnt]

https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/

So something like this in the tuya-convert folder:

python3 -m venv env
source env/bin/activate

Which will create a python 3 virtual environment and then activate it.

Then rerun install_prereq.sh to make sure the python files are in the virtual environment you just created.

Then run start_flash.sh

[Mrnt]

I’m not sure that setting the virtual environment will help you here, I got into the habit of doing it to have more control over what python modules are installed, but the tuya scripts will use python 3 anyway.

Have you checked your Linux is up to date?

Hi guys,

I'm having trouble to connect to the vtrust-flash wifi, too.
When I tap it on my phone or tables it seems to try to connect, but seconds later the network disappears. After refreshing the wifi list it shows again but I won't connect.

My setup:
Raspberry Pi 4 with fresh installed Raspberry Pi OS Lite from 2021-01-11

This is my smarthack-wifi.log :

Everything seems fine but I get an instant disconenct after the connect.
Can anybody help?

Had this issue also on a RPi (2b), it was solved by setting WiFi country via
$sudo raspi-config
After that my mobile was staying in the vtrust-flash wifi network.

Just to add this worked for me on a fresh RPI4 using latest Raspbian :)

[zeddski]

Ran into this (apparently) same issue.
Seemed that Wifi was being blocked by the Raspberry software, which is the default setting on some OS-es.

Fixed it with: "sudo rfkill unblock wifi" (if that doesn't work, replace "wifi" with "all").
Second: Although not the issue of @YannikW, make sure DNSMASQ is running, otherwise you won't get an IP address - which would explain why you cannot connect.

I am also experiencing this issue and none of the sugestion in the comments seem to have worked. Here are my log outputs when starting flash. Anyone have any ideas? By the way I am on Raspberry OS 64bit.
