assistant stop working after losing internet connection temporarily #188

Open daverck opened 7 years ago

daverck commented 7 years ago

Hi,

I have this issue with my raspberry.

When I ask something and the pi doesn't have internet, google tell me "there was a glitch", "please try again in a few seconds", ect. That's OK, but the when my internet connection come back up, google assistant keep saying it. I have a poor internet connection so this append quite often.

Is there any solution for this ?

Here are the service logs :

Thanks for reporting this! Could you try and reproduce this by disabling and enabling the Raspberry Pi's WiFi, instead of waiting for your connection to drop out?

If that behaves the same way, you can file an issue for the Assistant SDK including instructions on how to reproduce.

From the logs, it looks like the error is in an authentication thread created by the Assistant SDK, so that's almost certainly the place to fix it.

I think internet has to be down for a relatively long time. I cannot reproduce this right now bc I have a roommate and I don't want to annoy him.

Although I had the same error a few day back and that was also after I lost internet connection :

Hi, I've also experienced this. I've got a dodgy wifi area where the voice kit sits and if the connection drops then the assistant hangs.

LondonSi72 commented 6 years ago

My local Internet provider (BT) have provided a useless service recently with the internet dropping regularly. If I try to use the Assistant even after the Internet service is back up, the Assistant fails with a 'hmm, something went wrong, please try again in a few seconds'. I have to reboot to correct it. I'm thinking of running a service to check the internet access and rebooting if it detects it's dropped...

@LondonSi72 If you just restart the assistant instead of a reboot does that work?

@divx118 Sorry - missed your query. Yes restarting the service also works.

divx118 commented 6 years ago

@LondonSi72 Well I know it will be a workaround, but a simple shell script that pings www.google.com every 15 or so seconds and if it fails just restart the service.

@divx118 - yes. That's kind of what I was looking at doing as a workaround - I was just hoping for something programmatic :)

divx118 commented 6 years ago

@LondonSi72 Didn't test it, but something like below should do it. 

#!/bin/sh
OFFLINE=false
while true; do 
    if ping www.google.com -c 1|grep -q time; then
        echo online
        # Only restart service when there was an offline
        if $OFFLINE; then
            systemctl restart voice-recognizer.service
            OFFLINE=false
        fi
    else
        # Set restart service flag
        OFFLINE=true
        echo offline
    fi
    sleep 15
done

I corrected it a bit (was missing then and $)

#!/bin/sh

OFFLINE=false

while true;
do 
    if ping www.google.com -c 1|grep -q time;
    then
        echo online
        # Only restart service when there was an offline
    if $OFFLINE;
        then
            systemctl restart voice-recognizer.service
            OFFLINE=false
        fi
    else
        # Set restart service flag
        OFFLINE=true
        echo offline
    fi
    sleep 15
done

It would be better if the assistant handled losing internet connection correctly but that will do for now.

divx118 commented 6 years ago

@daverck oops sorry, corrected in the above code. I agree with you that the api should handle this. Thanks for keeping the issue open.

As I'm relatively new to Linux and creating init.d or rc.local or systemd started tasks is still a bit of a mystery, for me the simplest way of implementing your (really useful) script was to create it as an executable bash script and add it to crontab to start at reboot.

I removed the INIT related content, updated the systemctl command to run with sudo, saved the script as restart-voice-recognizer.sh, made it executable (chmod +x) and updated crontab as follows:

crontab -e

I chose nano as my editor of choice and added:

@reboot /home/pi/restart-voice-recognizer.sh

Here's the script I used (thanks to @divx118 for pointing out how to format this correctly):

#!/bin/sh

OFFLINE=false

while true;
do 
    if ping www.google.com -c 1|grep -q time;
    then
        echo online
        # Only restart service when there was an offline
    if $OFFLINE;
        then
            sudo systemctl restart voice-recognizer.service
            OFFLINE=false
        fi
    else
        # Set restart service flag
        OFFLINE=true
        echo offline
    fi
    sleep 15
done

@LondonSi72 You can post code as follows on github:

```sh
#!/bin/sh
OFFLINE=false
while true; do 
    if ping www.google.com -c 1|grep -q time; then
        echo online
        # Only restart service when there was an offline
        if $OFFLINE; then
            systemctl restart voice-recognizer.service
            OFFLINE=false
        fi
    else
        # Set restart service flag
        OFFLINE=true
        echo offline
    fi
    sleep 15
done
``` start with 3 back ticks and end with 3 back ticks after the first 3 you can add the 
language used so you get highlighting.

Result of the above

#!/bin/sh
OFFLINE=false
while true; do 
    if ping www.google.com -c 1|grep -q time; then
        echo online
        # Only restart service when there was an offline
        if $OFFLINE; then
            systemctl restart voice-recognizer.service
            OFFLINE=false
        fi
    else
        # Set restart service flag
        OFFLINE=true
        echo offline
    fi
    sleep 15
done

@divx118 Cool :) Thanks
