Hello,
I managed to build a Raspberry image for Linto by following the documentation provided at https://github.com/linto-ai/linto-os-generator

But I am unable to make Linto hear me or speaking.

From the admin webui, I can see that the Raspberry client is seen "online" and I can ping it.
But when I try to wake it up by saying "linto" or if I try to make it speaking from the admin webui, it doesn't work.

Here is a screenshot:

Here are details about my config:

• Stack deployed with the linto-platform-stack script.
• Running containers and services on the Docker swarm

• Here are the messages on Mosquitto when I do a "ping" and a "speak" from the admin webui:
  {"enrolled":true,"sn":"raspberry1","connexion":"online","config":{"network":[{"name":"wlan0","ip_address":"192.168.1.195","mac_address":"b8:27:eb:e3:ee:a6","gateway_ip":"192.168.1.254","netmask":"255.255.255.0","type":"Wireless"}],"firmware":"0.0.1","ftp":{"host":"","user":"","use_secure":"","password":"","port":""},"sound":{"input":"hw:0,1","output":"pulse","volume":"100","sensibility":"100","ww-sensibility":"100","tts_lang":"fr-FR"},"disk":{"root_expand":true,"mounts":{"root":"","tmp":"","var":"","storage":""}},"mqtt":{"scope":"blk","frommetopic":"fromlinto","towardsmetopic":"tolinto","client_id":"","clean":true,"host":"linto.maison.lan","port":"1883","username":"mqtt","password":"mqtt","uselogin":true,"keepalive":"10","protocol":"MQTT","keyfile":""}},"meeting":{"sessionid":false,"sessionname":"","recording":false,"localrecording":false,"remoterecording":false},"on":"2021-03-05T13:09:52.988Z"} {} {} {"value":"bonjour"} {} {}

NB: it seems the device (raspberry1) is seen online on Mosquitto ("connexion":"online")

• Audio setup tests on the Raspberry pi 3

-- rec /tmp/test.wav] --> OK
-- aplay -D pulse /tmp/test.wav --> OK (I can hear my voice recorded from the previous command)
-- systemctl status pulseaudio.service --> OK (I had to install the respaker 4 mic-rray drivers + activation of the embedded Raspberry sound card)

• linto-client config on the Raspberry
• • /home/pi/linto-client/.envdefault

`# Components loading in this order, components are orchestration plugins for the LinTO client actions
COMPONENTS = localmqtt,logicmqtt,audio

Local MQTT bus setup

LOCAL_MQTT_ADDRESS = linto.maison.lan --> DNS name of the mosquitto server, running the Linto docker stack
LOCAL_MQTT_PORT = 1883
LOCAL_MQTT_KEEP_ALIVE = 15

Audio and Mic

AUDIO_FILE = /tmp/command.raw
TTS_LANG = fr-FR,en-US,en-GB,es-ES,de-DE,it-IT

Local meeting Recording

MEETING_FILES_ROOT_DIR = /media
MEETING_FILES_ROOT_DIR_FAILBACK = /home/pi
`

I noticed that other linto-client stack serices also had a .envdefault file, pointing to a local mosquito server
I changed the configuration to point to the mosquitto container provided by the linto-stack (linto.maison.lan)
But it didn't see any reference of this configuration on documentation. Do I have to let the default configuration ? (localhost)

I did these changes:

/home/pi/command/.env_default:MQTT_LOCAL_HOST=linto.maison.lan /home/pi/linto-client/.envdefault:LOCAL_MQTT_ADDRESS = linto.maison.lan /home/pi/linto_tts/.env_default:MQTT_LOCAL_HOST=linto.maison.lan

I also changed this file as requested in documentation:

/home/pi/linto-client/lib/terminal/linto.json

{ "enrolled": true, "sn": "raspberry1", --> adapted to reflect the name of the Linto client I created on the admin webui "connexion": "online", "config": { "network": [ { "name": "wlan0", "ip_address": "192.168.1.195", "mac_address": "b8:27:eb:e3:ee:a6", "gateway_ip": "192.168.1.254", "netmask": "255.255.255.0", "type": "Wireless" } ], "firmware": "0.0.1", "ftp": { "host": "", "user": "", "use_secure": "", "password": "", "port": "" }, "sound": { "input": "hw:0,1", "output": "pulse", --> adapted to the pulseaudio configuration working with aplay -D pulse "volume": "100", "sensibility": "100", "ww-sensibility": "100", "tts_lang": "fr-FR" }, "disk": { "root_expand": true, "mounts": { "root": "", "tmp": "", "var": "", "storage": "" } }, "mqtt": { "scope": "blk", "frommetopic": "fromlinto", "towardsmetopic": "tolinto", "client_id": "", "clean": true, "host": "linto.maison.lan", "port": "1883", "username": "mqtt", "password": "mqtt", "uselogin": true, "keepalive": "10", "protocol": "MQTT", "keyfile": "" } }, "meeting": { "sessionid": false, "sessionname": "", "recording": false, "localrecording": false, "remoterecording": false }, "on": "2021-03-05T02:09:59.400Z" }

I als noticed that the "client" representing the Raspberry device was red on the admin webui, even if mosquitto reports it as reachable and I can ping it from the webui.

I hope I provided enough information.

Can someone help me troobleshooting this please ?

Thank you for your help

Best regards

Hello,

First, in order to create the OS image, I had to modified the 'generator.sh' file.
I don't know if it specific to my computer or not.
mount /dev/mapper/loop${LOOP_ID}p2 ${MNT} --> mount /dev/mapper/loop4${LOOP_ID}p2 ${MNT}
mount /dev/mapper/loop${LOOP_ID}p1 ${BOOT} --> mount /dev/mapper/loop4${LOOP_ID}p1 ${BOOT}
I added '4' after 'loop'.

Second, I have some issue to connect to the raspberry hosting Linto through ssh, password is wrong. When I try to be super user, I have the same problem. Are credentials correct? is it really pi as password?

Third, Linto is open source but what is the exact licence ?

Kind regards.

linto-os-generator/base/root_part/usr/local/bin/waitforsoundcard.sh doesn't work for other language than french:

[...]
l=`/usr/bin/aplay -l | grep périphérique | wc -l`
[...]

Hello,

Je teste le generator sur une Ubuntu 2020.04, et je rencontre plusieurs problèmes. J'ai ce log lorsque je fait les étapes : 1, 2, 2.1 et 4 :
