Have at it!. I have tried to make the host api as simple as possible, I was going to add virtual serial ports and rndis when I get back from vacation but if you guys wanna take a crack I am all for it.

I brought a CP210x usb -> serial device from spark fun. Ive started port bits of linux driver into your code, and things seems to work. As I have the 4 gpio pins working. But have no idea what the the usb urb structure is all about? Anyone been here before as looks like I will need to implement something like this

The CP210X uses 2 bulk endpoints for read/write. You shouldn't need much more than a USBBulkTransfer write on interface 0x01 and a async USBBulkTransfer on the in 0x81 endpoint. I have a few other serial cables lying about but won't have time to get to it until next week.

Hi Peter,

I am planning to have fun with BlueUSB and a wiimote. I have had a look to the documentation and LCP1768 mbed can be connected directly to the USB connector. I cannot figure out why you had to use 2x15k resistors ?

One question regarding the USB Bluetooth stick : you are using a CSR dongle, is this a limitation ?

I would be delighted if you could share more details on how to make the communication with the wiimote, that would help a lot.

Thanks

2 x 15k resistors are needed to pull the USB D+ and D- to ground when you configure the mbed USB controller as a host.

 

See Fig 35, page 274 of the NXP ref manual for the LPC1768.

(The 2 x 33R series resistors are already present on the mbed module.)

nice work,

anyone planning to use the BT stack from an Andriod powered phone ?

some work is progressing using it with an Arduino... http://code.google.com/p/android-bluetooth/  but im a Java noob, some it might be an uphill climb... :-/
Would be cool to control stuff using an mBed and an android phone though...

Pete or any other USB expert?

Ive got the baudrate settings working, and function to enable the uart. I would of thought the below would let me at least see an incoming stream. Stuck? it doesn't really error or give me any output.

for (;;)
{
         r = USBBulkTransfer(device,0x81,(u8*)data2,64);
    if (r > 0)
    {
        nBytes += r;
        printf("--> %d",data);
    }
    if (nBytes >= 1048575) break; // Break at 1MByte 
}

I am trying this out for the first time. It seems to be getting usb data ok judging from the normal hid stream from a usb keyboard (through a hub) but it is constantly printing the message " ProcessDoneQueue status".  Is this some kind of verbose message? When I plug in a bluetooth dongle, it does the same thing. At the start it sends "ProcessDoneQueue status  82 5  Inquiry Complete 1: 01  CALLBACK_INQUIRY_DONE then an infinite ProcessDoneQueue status  82 5 messages. Anybody got anything off the top of their heads?

regards

I did find the routine sending the message and commented it out and it does seem to work quite nicely. I am not a bluetooth expert. I would like to figure out how to make the mbed use what ever device it last paired with but I haven't figured that out yet. Following something with very limited debug features is kinda tough. Any suggestion would be appreciated.

Hi,

 

Great work ;-)  Got a wiMote connected, but im having problems using the Blueusb, when the mbed is powered 'normally' (w.o. the usb cable).

 

I thought it might be due to blocking getchar/putchar functions, but have em all commented out (rather timeconsuming using the mBed copile/editorr ;-/ ), and still i can only connect the wiiMote, when the mbed is plugged into mc PC's USBport.

Any ides, what causes it to hang ?

The plan is to use it as standalone, on a robot.....

How are you powering the USB socket? If you're using the VU pin, note that it's powered from the USB cable. If you use independent power, you'll have to power the USB socket separately.

That did the trick, thanx ;-)

I am new to Bluetooth. I have connected a Bluetooth USB onto mbed andI have the following msg (after commenting out the "ProcessDoneQueue status  82 5", otherwise, this msg loops forever). After the msg, I power on my WiiRemote and a Bluetooth headset, nothing happen. I tried to enter commands like list, scan and enquiry. Nothing happen. What is the normal behaviour when I power up a Wii Remote?

many thanks

Do I need to do anything such as pressing any key beside trying to pair a bluetooth device such as WiiMote to the mbed board?

 

I connected a USB mouse to it and it works fine. Only the Bluetooth USB thing doesn't work. I have confirmed the Bluetooth USB adaptor is working on a Windows XP. Do I need any specific Bluetooth USB adaptor. Mine is generic one with a half circle shape.

I had the same problem when I originally tried to use it with a keyboard and after looking around using printf statements it just suddenly started working. After I took out the printf statements it still worked. It has run for a few months now and worked great just so long as I re-pair it when I hit the reset button. I have never figured out how to get it to accept the last device used.

Wow! Amazing!

I'm new to USB. Could it be possible to access an USB camera, too? If so - how?

Thanks and regards.

Hi there!

I'm asking for an integration of an camera because I've rewritten the RPC stuff for .NET. Maybe the stream could be redirected over RPC from mbed to a microsoft device (phone7, micro framework, CE or something like this)? If you know something about how to handle a camera - let me know, please. Or is a cam no HID? Thanks.

Cheers!

Stanislaus

@Stanislaus Some usb cameras are high speed only and wont work on the lcp17xx. Others would work; did you have a specific device in mind?

http://read.pudn.com/downloads77/ebook/293318/USB%20Video%20Class%201_1/USB_Video_FAQ_1.1.pdf

 

Hi Peter,

no specific camera in mind. I want to use a serial camera - like Mr. Nakamura described in his article (http://mbed.org/users/shintamainjp/notebook/camera_c328_en/). But all (not to expensive) serial cameras are sold out. So I had the idea to use a USB camera and to redirect the data stream (320x200 pixel@8or15 if possible 20 FPS) to a Phone 7 app or to a PC - or only one picture. Don't know what's possible in general and with mbed? Thanks for the link you posted. I'll try to get more informations there. This is a starting point. Thank you for helping.

Hi Peter,

I have downloaded the USB COM port device deriver (mbedWinSerial_16466.exe) and tried to install.

The system “Windows XP 2002 SP3” says the following:

 

What should I do?

Hello all. I´m new on this type of host connection. Your BlueUSB it´s great . I test wiimote connection and move a servo with. I test usb hardisk and make a big datalogger and other programs. The only that  can´t is connect with a PC with a serial profile or other Bluetooth serial module  . Do you can do this with your library?

I have a circuit of quadcopter and mbed is perfect for this, now i use the standard radios i would use the bluetooth transport.

Have a nice day

Thanks

Hello all, Your library works well. Big thanks !!!

I'm trying to connect mbet to IMac with bluetooth on ubuntu with bluez and python.

I make a server listening for L2CAP connection  on channel 4097

Now i'm trying to modiffy your code.

I think the best place to insert mycode is in ConnectionComplete of testshell

But i'm new to c++.

I woult like something like

bt.open(server_addr, 4097);

bt.write("hello");

bt.close();

Please, could you give me some guidelines to achieve this ?

Should i make a  new class "Simple Bluetooth" like hidBluetooth ?

Or should i wait for RFcomm protocol ?

Thanks

 

 

Hi Peter, Your BlueUSB library is very good!! I controlled a m3pi with a Bluetooth keyboard. Thanks

Can you give some ideas how virtual serial ports would be added? Would it be feasible to make a bluetooth serial connection to a mobile phone (to make use of GPRS/GSM modem)? How does one go about pairing in this situation?

Thanks

I'm new to mbed and I would like to use this library. Can somebody  give me some advice on how to start using it?

Hallo,

where can I find how you to connect the mbed with the usb connector .

Fig 35.shows the USB OTG port configuration whithout pullup resistors.

Fig 36. shows the  USB host port configuration with 15K pull-up  but also with a LM3526-L for the VBus.

Did you connect VBus direct to 5 Volt ?

Thanks

Bernhard

Has anyone managed to write/integrate simple FTDI or similar drivers for serial comms yet?

I would like to use the USB pins for telemetry rather than wasting the second I2C port for my sensors in a port of some multicopter code (UAVX).

Thanks

Hi Peter,

 

I have got new mbed board. I want  to test blueUSB. How Can I power mbed board when I am using USB host. and how to load compiled bin file when using as USB host.

 

Thanks in advance

Has anyone managed to get Isochronous  transfers to work on top of blueusb?

Hi,

i want to know that can i use mbed as host device for usb modem stick (3G connection) it will be so amazing. But i dont know anything about usb modem sticks. I think Peter Barrett can figure it out.

Hi Peter,

I'm using your stack to interface to a CDC device. This type of device exposes two interfaces: a communication class with an interrupt endpoint and a data class with two bulk endpoints. Your stack only looks for interface zero and hence misses the two important bulk endpoints. I could easily fix it in your code but I was wondering why the restriction to interface 0 was there and if there is a way to use the second interface with API calls instead of meddling with your code.

regards,

Ad

Hi Paul,

It looks like you don't use the Bluetooth USB with CSR chip. I tried 2 USB Bluetooth, 1 can connect, other can't.  The working USB bluetooth is with CSR chip. I don't know the other one.

Hope that it helps!

An attempt to add PS3 Sixaxis support: http://mbed.org/users/BartJanssens/programs/PS3_BlueUSB/lq9h2h

Does it work with a particular USB hub? I've Gear Head 4-port USB 2.0 hub, and I don't see anything on serial terminal. I even tried without the hub, and nothing either. However, when I tried MSCUsbHost sample program, it works without the hub, but gave error message (I think) saying "In Host_Init Initializing Host Stack Host Initialized Connect a Mass Storage device".

Also, I tried with 15K pulldown resistors and without and MSCUsbHost program works either way. So do I need it? I'm using Cool Components workshop board, but my soldering for the two jumpers was a blob mess. :)

I use BlueUSB with hub and without and that works. The 15k resistors are to reliably detect plugging and unplugging. The example BlueUSB code of Peter Barrett is supposed to work with USB Mass Storage Devices. There are posts in the forum that this doesn't work. The code "as is" didn't work for me either. I haven't tried MSUsbHost but I think it is based on the same source (FatFileSystem).

@ Alex Chen // I even did not manage to get the Bluetooth System to run with a USB Stick. My system (myBLUEUSB from Ad van der Weiden) is also running on a Cool Components Workshop board with and without pullups. But the USB Mass Storage is not working at all. I am collecting Data from a Bluetooth GPS transmitter and a Wii Remote. Both work perfect. I also tried the BlueUSB code of Peter Barrett which also did not work. The only software is really the MSCUsbHost which works with several USB Sticks. So in lack of help i installed a second system system on the base of a normal second serial port, installed some new encoders and gyros, installed a 4Gb USB Stick and everything works perfect. It is really a pity but I am seriously thinking of forgetting the Bluetooth stuff but i am still not giving up.

Hey,

just simple question to make sure: Will this work on LPC2368 mbed board?  As I understand it wouldnt right?

Because I just wanted to use usb bluetooth dongle on it but cant get it working, and recently read some things that there is less functionality on USB on LPC2368. Is there any other way to use bluetooth dongle on LPC2368 to have conectivity via bluetooth?

Cheers,

Not 100% sure but it appears that the 2368 has no USB host interface so a standard USB BT dongle cannot be used. If you need BT, look for a serial to BT interface.

Yep, no host on the 2368 :/

I had a look into the MassStorage.cpp that comes with BlueUSB and apparently is not working right (File system borked error). The system was built for bulk-only transfers and some transfers return -102 (ENDPOINT_NOT_FOUND). My USB stick uses endpoints 0x02 and 0x81, the program from Barrett uses 0x01 and 0x81. Unfortunately these addresses are hardcoded and in one case even computed (flags|1). Nevertheless with a proper define of the endpoints and 3 little changes to DoSCSI, I got the listing of the root directory of my stick. It would of course be much nicer if the program would figure out the endpoints by itself. The functions SetConfigurationAndInterface and AddEndpoint in USBHost.cpp actually read the endpoint descriptors and even store the addresses in internal data structures, they are however not easily accessible to user programs.

I have it automatic now. The interface descriptor is parsed again in 'OnLoadDevice', the ep addresses are extracted and passed as extra parameters to 'OnDiskInsert'. USBFileSystem now also derives from USBSCSI which wraps all the non-OOP stuff in MassStorage.cpp. USBSCSI has the endpoints and the device as members, so the device parameter is removed from all members except 'SetDevice'.

'main' looks now like this:

<<code>>

    //int _device;
    u32 _blockSize;

After changing the 'main' module to your suggestions i cannot compile my source anymore. As i am C++ newbie it is difficult for me to understand what is wrong and what is right. These are the errors: "not a class or struct name" in file "main.cpp" pointing to USBSCI" "argument of type "u32 *" is incompatible with parameter of type "int" pointing to SCSIReadCapacity(&_blockCount,&_blockSize); and so on. Must the lib myUSBHost be changed completely ?

Yes, this is not the complete program but just an indication of how I solved it. As I said the underlying problem is the addresses of the endpoints. The endpoints are shown right after reset (something like A:81). These endpoints appear in DoSCSI in three places, the easiest solution is to fix it manually (for your stick). The automatic solution involves changes to MassStorage and AutoEvents as well.

@voy ager

I republished the program and libraries, I hope you can piece everything together.

@ Ad Thanks Ad, could put everything together. Works perfect.

After 11 Hours the mbed Bluetooth System stopped working. The BT GPS is still sending data. I can follow that on a second computer. But the mbed is just hanging. What a success. I really think the whole system is not very reliable.

Hm, sorry to hear that. Maybe there is a small memory leak. How about printing the available memory every 15 minutes. There can be a real leak or possibly huge fragmentation. The first one we have to find, the latter we may be able to solve with fixed buffers. On the other hand it may have a totally different cause.

BTW I think you are right about the reliability, the myBlueUSB is pieced together from different sources plus some of my own. If someone would pay me the right price I would invest some months to do it properly. But I guess a commercial stack would be a lot cheaper then. But hey, it's open source, I extended and improved the work of Barrett (who probably didn't start from scratch either), anybody should feel free to improve it further.

 

Hi

I connected the mbed in host mode to a keyboard. It works, but I have the callback function continuously called (AutoEventCallback) with the

u8 auto_keyboard[8]

 

structure updated, is there a way of decoding in ASCII and getting the sentence until a Key Enter press ?

my iinterest is to use a RFID USB reader (which works as a HID) but I have only this when I connect and the standard programm do not have an AutoEvent or so...

Hello Peter,

Is it possible to emulate a bluetooth HID keyboard? It would be really interesting to create bluetooth remotes for telephones.

Thanks, Raisin

Hello Peter, I think I want to send the state of the switch on the pc from mbed Blutooth. What should I do? Is it OK if you change the Testshell?

man, is it possible connect (using this program)a cellphone(through bluetooh) and the mbed which uses usb-bluetooth dongle?

is (1) connected to miniUSB mbed port?

Hi Hieu Bui,

The problem with the Nokia E71 and blue-tooth connections is well known, it's kind of general issue in the Nokia firmware of the E71,

i've got this problem too, sometimes it even works for a while. It drives you nuts. I've had this connection problem with my headset, with my Garmin-GPS and also with my CAR-kit. All the same; so start looking with google i've found the problem is the Nokia E71 (on their own forum), they only connect to stuff from Nokia, only the original frimwareversion wouldn't have this problem. So, when you'll have another phone you can start again ;-)

Nokia has even an free update for BMW to fix the connection problem with the GPS. Unbelievable.

Good day! I'm from Argentina and wanted to know if there is any explanation of BlueUSB code or a tutorial, because I find it very difficult to code and way too enteder especially complicated to me the translation into Castilian. From already thank you very much! Lucas E. Blanco

Hello, I'm having some problems that can not solve. I can't connect in other device and I don't know why. Does anyone have an idea? And soon, how can I accept a transfer of other device(Ex: A photo)?

Also, I want to connect a USB GPS device that normally presents itself to a PC as a USB virtual serial port, at 4800 baud, as I recall, to the hub to read lat, lon, etc.

Does BlueUSB support virtual comm type connections in some manner?

If so, does anybody have a working program to share?

Thanks a bunch.

Because it is not suitable for the new version of the compiler this program, please update

Greetings Guys:

I am interested in looking at and studying up on the class blueUSB.  Is it a cless that is already in the compiler?

I will try and keep a look for an answer on here but if you dow have the answer please send it to me at triad@wowway.com.

 

Thanks

There is a link directly under the picture with the code.

Hiya,

Apparently, CSR dongles will work and Toshiba chipsets won't. I accidentally bought a Toshiba one and it didn't work. I'll get my hands on a CSR one and give that a go instead!

Cheers,

Hi...

I got the WiiMote to work fine, but now I want the Nunchuck to work also. I tried to se if the data was on d[?] but it seems as there is only data from the Wiimote.

Anyone got an idea on how I access the data from the Wii Nunchuck?

Best regards

Hello,

Is Blue USB compatible with a newly added mbed board i.e. the FRDM-KL25Z ?

I am looking to connect a Thumbdrive to it to log analog measured data.

Thanks !
