Unable to connect to vtrust-flash #551

jayanthb007 · 2020-02-22T20:42:42Z

Thanks for the amazing work you have done on this project and your continued support.

I'm having issues connecting to the SSID vtrust-flash which is being broadcasted, my phone says unable to connect.
I've tried with both Ubuntu 18.04 and Raspberry Pi desktop running on Oracle VM VirtualBox. For the wifi adapter I'm using Ralink RT5370. I've tried both docker image and regular start_flash.sh method and got stuck at the same step where I'm supposed to connect to vtrust-flash on my phone.

Let me know if you need more information. Appreciate your help and support.

Thanks
Jay

Connect any other device (a smartphone or something) to the WIFI vtrust-flash
This step is IMPORTANT otherwise the smartconfig may not work!
Put your IoT device in autoconfig/smartconfig/pairing mode (LED will blink fast). This is usually done by pressing and holding the primary button of the device
Make sure nothing else is plugged into your IoT device while attempting to flash.

Hi Jay,

Can you check your /scripts and /backup directories to see if you have any *.log files?

jayanthb007 · 2020-02-22T22:46:01Z

Hi Colin, Thanks for a quick turnaround on this. I'm attaching those logs. Jay

Are you able to successfully use the hotspot feature of the OS?

kueblc · 2020-02-23T16:01:05Z

If you have create_ap installed, you could also try the create-ap fork.

git clone -b create-ap https://github.com/kueblc/tuya-convert.git

@kueblc: I just bought a raspberry pi 4b and installed Raspbian Buster Lite on it and ran the start_flash but this time I don't even see the vtrust_flash ssid. Please see the log attached. Am I missing wifi drivers?

It's fixed and I was able to successfully flash one of the tuya switches I had. Not sure exactly what I did to fix it but couple of reboots and setting up wifi network through raspi-config fixed it for me.

I will attempt to flash it on the VM again just to see if it works and post my update just so it helps others who are having the same issue

I did note this in your log:

Which you can address with rfkill unblock wifi

Baldorian44 · 2020-02-24T18:04:41Z

Hello, I seem to have the same problem, i've attached my file - although it seems related to "wlan0 could not connect to kernel driver" error instead, any idea how to fix that mr wise kueblc :)

smarthack-wifi.log

I tried your command with "rfkill unblock wifi" which seems to have removed that block, now i have the issue with the kernel...

kueblc · 2020-02-24T18:08:03Z

Don't worry about:

wlan0: Could not connect to kernel driver

This is not a problem unto itself.

Do you see vtrust-flash SSID from another device?

Baldorian44 · 2020-02-24T18:26:26Z

Ok cool.
No i dont, i've tried to search for it under WiFi settings under two different android phones and 1 laptop.. nothing shows up in the available WiFi's, I have even tried to make a manual network, no luck.

It should just appear as a standard WiFi network right?

Baldorian44 · 2020-02-24T18:33:08Z

Yeah now i see it, seems like your command worked after a bit of patience :)
Now i just have to figure out the last step of flashing the Gosund plugs :)
Thanks!

@kueblc I noticed that if I remove the setting --redirect-to-localhost setting in the line 20 of start_flash.sh. I'm able to connect to vtrust-flash with the VM approach but I'm still unable to flash. Does this help to understand what could be causing the issue?

kueblc · 2020-02-25T17:33:31Z

This could mean that the device you are connecting with expects an internet connection, and disconnects when it realizes there is none. However this is intended, we do not want a connection to the outside internet, so you must force the device to stay connected anyway.

With my Android device, it might say something like "No internet connection, won't automatically reconnect", but if I manually reconnect after that it will stay.

Do any other logs show activity?

i'm using an iPhone to connect to the AP and it does allow to connect to networks which doesn't have internet connections. I have tried to connect to vtrust-flash from my windows laptop and it says unable to connect too. I know that the usb wifi adapter is capable of hosting an AP. I have tried following create_ap examples and I'm able to connect to the ap i made up.
Bridged Internet sharing:
create_ap -m bridge wlan0 eth0 testnet
Bridged Internet sharing (pre-configured bridge interface):
create_ap -m bridge wlan0 br0 testnet

Also if I comment the below line it aloows me to connect to vtrust-flash. My guess is there is something happening in redirecting to the fake webserver created at 10.42.42.1

$screen_with_log smarthack-web.log -S smarthack-web -m -d ./fake-registration-server.py

I will attach the logs in the next reply.

For me the whole procedure is not working and I've debugged it down to the vtrust-flash SSID

I understand that its using hostapd to create the SSID and dnsmasq to provide the dhcp addresses.

What happens for me is that when I first try to connect my smartphone to the vtrust-flash network I don't get a sustained connection under Android 10. Andoid 10 keeps trying and failing. I tired an iOS smartphone, but it too is having difficulty.

I am using a Pi 3B+ with Buster and all fixes applied

Presumably if the smartphone (first device) can get a WiFo connection with valid 10.42.42..x address then it is pointless going to the next step where you try to talk to the power switch (in my case)

I've got an RPi4, I seem to have similar issues as above, no vtrust-flash network appearing. And the same start_flash log:

I have the same issue on RPi 4. I have flashed many devices with no problem using Ubuntu running on an old MacBook Pro, but I cannot connect to vtrust-flash with the Pi. I can see vtrust-flash but a connection is never established. I have tried with iPhone and also with a script running on another ESP8266.

I managed to get it working, I confirmed hostapd was working ok by doing this. It seemed to take a lot longer to connect to vtrust-flash than it does with my Ubuntu box, so I am not sure if I was just being impatient.

therealhammer · 2020-07-04T18:50:47Z

I had kind of the same problem. I could (sometimes) see the SSID of the vtrust-flash.

What worked for me (after many hours of not finding the bug whatsoever) was changing the Wifi channel of the network. You can do this by changing the value of "channel" in the file "scripts/hostapd.conf" to a value between 1 and 14 that fits best for your environment/neighborhood. I used the Wifi Analyzer app for finding empty channels. (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en)

I live in a house with some shitty routers that wont search for empty channels but just use channel 1. So 3 other routers where simply just "louder" than the little wifi dongle I bought.

Thought i'd share it in case someone runs into the same issue.
