Bluetooth and sensor Tag Texas: list of services of the gatt evil?

Hello

I have some experience with my Dev C ALpha and the Texas sensor tag.

In fact I am following this guide: https://www.bluetooth.org/en-us/Documents/Bluetooth%20SIG%20developer%20Training%20day%20-%20Woolley...

I would like the list of all the services available on the sensor Tag

I have a function within my app that does something like this:

the initialization of the BT
{if (bt_device_init (ApplicationUI::btEvent)==0)}
qDebug()< "device="" init="">
If (bt_ldev_get_power ())
bt_ldev_set_power (true); turn on the bt
{if (bt_gatt_init(&m_gatt_cb)! = 0)}
qDebug()< "gatt="" init="">
}

searchLab-> setProperty ("text", "investigation of departure!"); a label

{if (bt_disc_start_inquiry (BT_INQUIRY_GIAC) == 0)}
deviceCount int = 0, i, z;
bt_remote_device_t * remote_device_array = bt_disc_retrieve_devices (BT_DISCOVERY_CACHED, & deviceCount);
QString newDevs is QString ("devices found % 1") .arg (deviceCount);.
searchLab-> setProperty ("text", newDevs);
{if(deviceCount>0)}
for (i = 0; i
devName char [256];
bt_rdev_get_remote_name (remote_device_array [i], devName, 256);
qDebug()< "found:="" "="">< devname="">
const bt_remote_device_t * found = remote_device_array [i];

If (bt_rdev_get_type (found) == BT_DEVICE_TYPE_LE_PUBLIC) {}
{if (bt_rdev_pair (found)! = 0)}
qDebug()< "failed="">
}
char * gattServices = bt_rdev_get_services_gatt (found);
qDebug()< "...services="" for:="" "=""><>

{if (gattServices)}
z = 0;
{while(gattServices[z]!=null)}
qDebug()<>
z ++ ;
}
} else {}
qDebug()< "no="" gatt="" services="">
}
break;
}
}
bt_rdev_free_array (remote_device_array);
}
}

} else {}
qDebug()< "device="" bt="" init="">
}

This code for a Bluetooth device search THE autour and he's trying to list on the console of each service on the devce.

The result is:

I have 2 problems:

1: it is necessary to Pairing? If I try to use a Linux bluetooth usb dongle by following this guide: http://joost.damad.be/2013/08/experiments-with-bluetooth-low-energy.html it works and there is no need to make matching Tag and Dev Alpha C sensor... If I don't pair the devices... I have 0 return services.

2nd: running the unit with the order explained here http://joost.damad.be/2013/08/experiments-with-bluetooth-low-energy.html I have these lists of services

It is different from my request... why?

Thank you

1 matching is not always necessary. It depends on the device. What you should do in general is to go into settings Bluetooth on your BlackBerry and when you see the Tag TI sensor for the first time, select it. If you are required to enter a PIN, you will need to at this point. The status of the device in the settings must now move on to the connected mode or matched depending on whether or not he had a PIN. Other devices in the list will probably have a status of 'Saved' which means that they have been connected to or matched with previously and their details recorded in the cache device Bluetooth BlackBerry. If a device is in the correct state (connected or combined) in the list of parameters, then you need to perform a pairing programmatically.

2. regarding your apparently different service lists, they are in fact equivalent. I'm interlaced the BlackBerry API output with that of your Linux tool below:

The reason why some of them are "short" is that the two 16-bit 128-bit UUID and UUID are defined and the specification defines a UUID of base to convert 16-bit versions in the 128-bit versions. It is probably making your Linux tool.

  • Is it possible to remove the &lt; inbuf &gt; and &lt; outbuf &gt; tags of a Tuxedo Service exposed salt?

    Hi all

    Currently I have to expose my tuxedo Service in a WSDL file pre-created (with all the field names and namespaces already defined). Search the web and the examples in the tuxedo and salt package, I was able to configure most of the fields but still can't remove the inbuf wrapper tag.

    Y at - it no setting or configuration that I can use to remove this tag, so I can expose the WSDL generated salt as I wish? Or is it an obligation for each service in Tuxedo to have his entry exposed in this way using salt?

  • I've been playing with services.msc now I can't download anything and I do not know what services allows the download

    im sure it is a result of deactivation and activation of services, I was also a lot so just trying to figure out which are useless and I can't run restore system or something like that, I just need help so that I can download an anti virus and updates, so the download controls? What service? This isn't a problem of IE. If anyone has any ideas for me that does not involve downloading something else, or the copying of files from drive of windows or putting forms those are all out of the question.

    even when services are basic, only 3 services are enabled, and I can't even access the internet, so I just need to know what essential services are Internet ONLY.

    To repair the damage you have done, run system restore to get the best results.

  • Problem pairing and using Bluetooth THE TI sensor Tag with Z10

    I can't pair and use THE TI Bluetooth sensor Tag with my Z10 on OS version 10.1.0.273.

    I can find out the sensor with bt_disc_retrieve_devices Tag, but when I try to pair with bt_rdev_pair, I get an "Operation not permitted" error (EPERM). If I skip the step of pairing and just the list of services with a bt_rdev_get_services, I get an error "No such file or directory" (ENOENT). Same thing happens in the settings menu bluetooth where I can see the device, but it fails to the pair.

    And then, when I try to connect directly to a service with bt_gatt_connect_service, I get an error 'No such device' (ENODEV), which leads me to believe that I have to be paired first to connect to a service.

    The sensor Tag I pairs and connects very well with an iPhone 4S and on the flipside, my pairs fine Z10 with other devices THE bluetooth so I don't know which side prevents matching. I was actually at the session of JAM62 to BB Live 2013 and devices we were seemed to pair well with the TI sensor tag. Not sure if the version of the OS has nothing to do with it.

    Anyone else having these issues with the TI sensor Tag matching or know of ways to solve this?

    Updated the Tag TI with TI WHEAT SDK 1.3.2 sensor and now it matches successfully. Thank you!

    This is how it works in CS6, too.  And it's not just for definition lists.  This is the result expected any list type that you use.   DW knows not where the DTs and DDs begin and end because you have highlighted an entire paragraph and asked DW format as a distribution list.

    I code my own definition of lists in general.  It is faster.

  • Profiles BlueTooth scale and the GATT

    Hello

    I use an example of GATT BlueTooth to activate connection with scale of Wahoo. The scale is the utility (after it is combined and registered in the BlueTooth settings UI). It lists several standard services and the other (0 x 1901) is not in any of the documents of the GATT on the site of BlueTooth.

    In addition, under this service, there are three characteristics listed, one of which is 0x2A1C, TEMPERATURE_MEASUREMENT...

    Now, since there is no profile of the GATT for WEIGHT, Wahoo using temperature profile of the GATT to pass the measure of weight through?

    I've heard of Wahoo. It turns out that the service of weight exist, but it is not official. Example of application of the GATT sniffed out correctly, but not could not name it
