respeaker / get_started_with_respeaker Goto Github PK

hi,

i have tried fristboot and the other way copieing the script on SD Card for autorun which was explained in https://github.com/respeaker/get_started_with_respeaker/wiki/factory-reset, but both ways doesn't work. at firstboot i get error back "/dev/mtdblock6 is not mounted
/dev/mtdblock6 will be erased on next mount". sd autorun doesnt do anything. If i remove SD card and try to start without but respeaker wont work without sdcard. nothing is working. at df -h following is printed:

Filesystem Size Used Available Use% Mounted on

i dont know what to do anymore. at the moment respeaker is a very expencive paperweight. Nothing is working :-(

PLEASE help me,

Dear ReSpeaker team,

I am posting here, with more details, the issue that we are having reading ReSpeaker Mic Array data from HID on Raspberry Pi. (The REPORT_AUTO data can be read correctly though, so the problem might not be related to HID.)

Setup:

• Raspberry Pi 3 Model B V1.2:

$ uname -a
Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux

• pyusb:

$ pip show pyusb
---
Name: pyusb
Version: 1.0.0
Location: /usr/local/lib/python2.7/dist-packages
Requires: 

• respeaker:

$ pip show respeaker
---
Name: respeaker
Version: 0.4.2
Location: /usr/local/lib/python2.7/dist-packages
Requires: 

• ReSpeaker Microphone Array v1.0 08/29/2016
• ReSpeaker connected to Raspberry Pi MicroUSB cable

Description of the problem:

Problems appear when reading register values using the mic_array.py sample program.

$ sudo python mic_array.py w 0x0000 0x05050501
$ sudo python mic_array.py r 0x0000
[158, 55, 165, 16]

We would expect to receive [5, 5, 5, 1] in this case.
Also, reading any other address always returns the same values:

$ sudo python mic_array.py r 0x0003
[158, 55, 165, 16]
$ sudo python mic_array.py r 0x0004
[158, 55, 165, 16]

Also to be noted:

• After plugging the ReSpeaker Mic Array into the Raspberry Pi, the two first reads are always different, but from the third read, the same values are always returned:

$ sudo python mic_array.py r 0x0008
[0, 0, 0, 0]
$ sudo python mic_array.py w 0x0008 0x00010203
$ sudo python mic_array.py r 0x0008
[1, 0, 0, 0]
$ sudo python mic_array.py w 0x0008 0x000a0b0c
$ sudo python mic_array.py r 0x0008
[158, 55, 165, 16]
$ sudo python mic_array.py w 0x0008 0x00a1b2c3
$ sudo python mic_array.py r 0x0008
[158, 55, 165, 16]

• After modifying the mic_array.py sample program, the voice angle and VAD state where correctly read from the REPORT_AUTO message, but not when reading directly at the address of the value (0x44 for voice angle, 0x40 for VAD state).

Thank you in advance for your investigation into this. Please feel free to ask for additional information if needed.
Best regards,

I found two issues:

1. I have a dash character in the SSID of my access point. When I connect to ReSpeakerXXXXXX, it shows just the part of the text before the dash, and never connects. I setup an access point with no dashes, and was able to select that access point.

2. The new access point had a password with a dollar character '$' and an asterisk '*'. It accepted the password, but wouldn't connect. I looked at /etc/config/wireless, and the password field did not include those two characters. I edited the file by hand to add the characters and was able to connect.

how to change keyword ?

I went through the SD expansion instructions and was able to setup the overlay fs; however, the second FAT partition mentioned in the docs is not mounted.

root@ReSpeaker:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 5.2G 16.8M 4.9G 0% /
/dev/root 29.0M 29.0M 0 100% /rom

overlayfs:/overlay 5.2G 16.8M 4.9G 0% /
tmpfs 512.0K 0 512.0K 0% /dev

I see the following in the event log:

Wed Jan 25 22:24:13 2017 user.crit mountd[1698] /tmp/run/mountd/mmcblk0p2 has expired... unmounting
Wed Jan 25 22:24:13 2017 user.crit mountd[1698] finished unmounting

Wed Jan 25 22:24:13 2017 user.crit mountd[1698] finished unmounting

Mountd is automounting both partitions to /Media, but this is not what is showing in your example. Please update your docs.

UPDATE: I should probably start a new issue for this as I was confused about what was happening when I wrote this. But the instructions do need updating to explain how to connect to the Respeaker web app from a machine connected to your Internet Wifi (rather than the Respeaker Access point). For example, they should mention using respeaker.local.

My Respeaker worked for a while but is now giving

Access to 192.168.100.1 was denied

You don't have authorisation to view this page.
HTTP ERROR 403

I can log into it by a serial console, and it is getting an IP address from my router.

Speech recognition did not work for me as the Bing Speech recognition API seems to be down at the moment.

I often get this error when attempting to do speech recognition, e.g when using alexa:

root@ReSpeaker:~# alexa
Expression 'parameters->channelCount <= maxChans' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1513

IOError: [Errno -9998] Invalid number of channels

It usually goes away if I reboot the device.

Just to find does the microphone array removed background noise?
I also wanted to find out how to get final beamforming data.

So when I run the bing_speech_api.py I get this error:
INFO:mic:etected respeaker

I think this is an auth issue so I'm wondering where should the bing key go besides playmusic.py and if there's something else I'm missing. Thanks!

Recently I try to execute a Bing python file test.py on respeaker, and always when I try to run, receive the next message:

I reboot the respeaker and try again but always got the same error, any idea?

Asked this over on the forum but i guess we are supposed to ask here:

I am getting inevitable loud corrupted frames from the mic array while connected over USB after a certain amount of time. It varies. It will sound great for a while and then eventually start slowly corrupting the audio until you can't hear it, even after successive recording attempts. It feels like something in the XMOS firmware is not working properly. Here's an example of the noise I'm getting:

https://soundcloud.com/bwhitman/respeaker-mic-array-test

I am just saying "test" alone in a quiet room; all the other noises seem artificial.

gst-launch-1.0 playbin uri=http://music.163.com/song/media/outer/url?id=4898911&userid=122545507
will fail,
but
gst-launch-1.0 souphttpsrc location="http://music.163.com/song/media/outer/url?id=4898911&userid=122545507" ! mad ! alsasink
will work well.

The issue affects gstreamer based applications such as gmediarender and mopidy

which config file the openwrt used ?

Just opened the pack and connected first time.
Using iPhone Found my ReSpeaker's wifi which i connected...
Selected Wifi and added password...
But when using Laptop i go to the ip 192.168.100.1 using Chrome i get an error window....

and when clicked ok...

Also not able to find any documentation explaining the Light indication meanings and use of Navigation Button...

Thanks in advance

Hello

I am having problems to connect the respeaker to the wireless network.
I tried it via the Wifi settings page. It can see my wireless network. When i enter the password and try to connect it says: Failed to connect.

Afterwards i tried via the command line command wictl like they mentioned:

`root@ReSpeaker:~#wictl

2,WiFi-2.4-8220

anyone an idea?

Can I get multi-channel MIC data with the ReSpeaker Mic Array board thru USB to PC?
Is the MIC data just Raw from the microphone without processed?
Do I need to configure the board to get the Mic raw data? How to do it?

Summary

I changed the password for the router/respeaker GUI, did some more work, restarted and now cannot login to GUI, but can to SSH.

Background

I changed the password for the GUI, and then went through the SD Card setup. At the end, I did a "reboot" in the terminal.

Upon restart, I login to respeaker via SSH, and realized I don't have Internet connectivity. I go to the GUI to login, and get this error as the page opens:

I hit OK on the dialog (not shown above), and get this login screen:

Neither my old, new, or default root passwords work. (FYI I also changed the IP address, before all the above, and rebooted with that fine.)

Sum up

How I can:

1. Get myself logged in without resetting? I do have a backup of my settings prior, but if I don't have to run firstboot and understand the issue, I'd be a lot happier.

2. Figure out how to get my respeaker properly on the Internet?

Hi,

I have a BING_KEY insert to playmusic.py. but it return the following result.... how can i get it work?

When i setup Extend Storage, it always said "Read-only file system" what can i do?

There does not seem to be a documented way to tidily shut down the ReSpeaker.

I have tried halt and poweroff commands but they both reboot the device.

When I just remove the power I usually get a message on the next boot:

FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

The fsck command does not seem to be available.

I have formatted my SD card as extroot following the instructions.

Hi, I try to use your example to translate words in another language, (e.g. Spanish), I analyze your api file "bing_speech_api.py" and try to test with next modification:

compile the library and execute the example with the library, but only converts numbers not words, (e.g. if I say to respeaker: "uno dos tres", this show "Recognized uno dos tres", but if I say "Hola, ¿cómo estas?", nothing appears)

appreciate your help on this.

regards.

Bad flash from arduino, now no longer being detected as a device over USB.

Any thoughts on cause? Are the ICSP pins broken out?

"We’ve developed a plug-in system that would continuously expand ReSpeaker’s features and functionalities in the future " where is plug-in system

Is there a way to get the audio source direction from respeaker microphone array?
any api available?

I have added my ReSpeaker to Alexa. When checking it's status on the Settings-page in alexa.amazon.com it always is shown as offline:

I have 2 question:

1. Is there something we can do about this?
2. Is this the cause that Alexa doesn't work with TuneIn news or streaming music?

i have compiled the source and upgraded the Respeaker,it panic ! can somebody help to find what the issue is ?

Wondering if this is related or there is something else is wrong.

Is there something specific about the ReSpeaker and its WAN connection to the Internet. I do not generally have problems using the wifi on my Netgear R7000 which supports 2.4G and 5G wifi. I would expect the ReSpeaker to be able to detect the SSID of the 2.4G wifi on the Netgear but it cannot. The ReSpeaker can see the wifi on another model of router. How can the incompatibility be resolved.

Hi,

I installed Alexa on ReSpeaker successfully, but when i added the link of my google account in www.alexa.amazon.com setting page, it doesn't work. Alexa is not able to register any event to the calendar and always says (voice) there is no account linked to Alexa and asks to register from setting page of Alexa. registration is done but doesn't work.

Would appreciate if someone can help me on this.

Regards,

After flashing update from SD respeaker isn't booting correctly anymore.
See error log below.
Please advise on how to resolve this. Thank you

When calling:

mic = Microphone(quit_event=quit_event)

from python, I often get.

Expression 'parameters->channelCount <= maxChans' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1513
Expression 'ValidateParameters( inputParameters, hostApi, StreamDirection_In )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2813

I sometimes get a segmentation fault. Occasionally, it works.

It works OK if mopidy is not running, but as I am trying to control mopidy by voice command via an mpc client, this is not an option.

If there is a better place to raise these issues, please let me know.

Hi, as subject, can please help advice on this, below is the log record, thank you

I started a new issue for this.

When I try the sample python program and say "Respeaker play music" I get:

INFO:mic:etected respeaker
000000000000000000000000000000000000000000000000000Wake up
INFO:mic:Start listening
DEBUG:requests.packages.urllib3.connectionpool:"POST /token/issueToken HTTP/1.1" 401 143
0000000000000000recognition connection failed

I am using a key generated as explained in the instructions. There are two keys generated Key 1 and Key 2 as shown in the instructions. I am using Key 1. Is that correct?

It may be that the Bing Speech API is currently not available.

Hi, me again. Is there any method to install SOX or FLAC on respeaker, I assume that is necessary compile but I hope it is not so.

does anyone have change the wake up word ?

I have a problem during the respeaker test.
I work after a factory reset.

I currently go through the steps to install pyaudio. like this -> Python packages on Respeaker

However, the following error occurs.

building '_portaudio' extension
creating build/tem.linux-mips-2.7

creating build/temp.linux-mips-2.7/src

ccache_cc -fno-trict-aliasing -Os -pipe -mno-branch-likely -mips32r2 -mtne=24kec -mdsp -fn-caller-saves -fhonour-copts -Wno-error=unused-but-set-vaiable -msoft-float -DNDEBUG -fno-inline -DNDEBUG -Os -pipe -mno-branch-like -mips32r2 -mtune=24kec -mdsp -fno-caller-saves -fhonour-copts -Wno-error=used-but-set-variable -msoft-float -fPIC -I/usr/include/python2.7 -c src/_poaudiomodule.c -o build/temp.linux-mips-2.7/src/portaudiomodule.o
unableo execute 'ccache_cc': No such file or directory
error: command 'ccache' failed with exit status 1

It does not seem to "ccache_cc" on the current respeaker linux.
Please tell me the answer for this problem.

http://www.mkdocs.org/ Provides excellent support for documentation written in markdown.

I have forked this repo and made it compatible with MkDocs already, Check the final result here https://d34dman.github.io/get_started_with_respeaker/.

Advantages

1. Better browsing experience
2. Supports search
3. Provides Edit link on the document itself, while it is being viewed.
4. Cleaner navigation architecture (Autodiscovery of headings)
5. We get support for admonitions which are cool features that can be used to attract user attention. (for example special theming for "note", "alert", "warning" etc...)

The Catch

1. MkDocs doesn't fully support GitHub flavoured markdown. So far the only incompatibility i have noticed is the use of "```" along with "4 spaces" intend to highlight code. The workaround is simple. We have to stop using "4 spaces" intend.

2. To publish the document, we would have to perform an extra step. Basically mkdocs gh-deploy has to be run in the root directory to publish the document on GitHub Pages. Alternatively if we host the document on readthedocs.io then we don't have to worry about this. They implement a githook which automatically builds the document upon change.
   (Readthedocs integration can be tested at http://get-started-with-respeaker.readthedocs.io/en/latest/)

Let me know if you like the concept and i can help you port your latest document HEAD over to MKDocs.

I am excited to try out the Respeaker Pro I purchased, but I am having a difficult time understanding how to use it. I really just want to use the Respeaker to show the weather, but the instructions on the "instructables" website are unclear and files are missing. Can someone just put together a packet file with everything I need in it to get the Respeaker to work. I am very new to Arduino and I need lots of help understanding how to upload code. The use of this program called PuTTy is also very confusing. Without someones help, I just have an expensive piece of technology that doesn't do anything except light up when I talk to it.

Please help me, (a stupid and confused person), figure this out. Thank You!!

Hi, recently I tried to install a Pygame with command "pip install pygame" and receive the next error:

I understand that S.O. is OpenWRT, are any other method to install python-pygame into this version?

While Alexa.py is running, even though respeaker is still active as Airplay device , the sound doesn't go thru or does with very low quality / bitrate.

I tried to connect a mic array to Ubuntu / Fedora / raspbian.
but i can't find respeaker mic array.

arecord -l -> nothing
lsmod -> nothing
lsusb -> nothing

Q1. How can i connect mic array to Other Linux Stystem?

I tried to connect a mic array to respeaker core
but i can't find respeaker mic array.

Q2. What is the meaning of "MTK APSoC I2S" displayed on the respeaker core?
respeaker core on Mic? or Mic array?
