android - BluetoothGatt showing 10,000 identical characteristics for service -

-

i've got problem i'm flummoxed about, because of how persistent is.

i writing small android app communicate bluegiga ble113. i've connected device before, i'd made gatt modification not being reflected on android device (in none of apps tried - , verified desktop , ios app gatt updated expected).

i tried turning off/on bluetooth , restarting nexus 7, , still nothing. finally, got desperate , tried solution mentioned here: https://stackoverflow.com/a/22709467/992509 uses reflection hit private bluetoothgatt method called refresh.

it seemed work perfectly, new service showing up, however, ran service (with 1 characteristic) showing few hundred characteristics same uuid. number of identical characteristics climbed everytime ran app, , through device restarts , bt cycling.

finally, got desperate , did factory reset on nexus (it's test device, don't care). didn't fix thing, , image shows i'm seeing (10k characteristics):

bluetoothgatt 10k characteristics

my ble113 gatt looks this:

<service uuid="deadbeef-cdcd-cdcd-cdcd-cdcdcdcdcdcd">     <description>debugging service</description>     <characteristic uuid="deadbeef-0000-0000-0000-000000000000" id="xgatt_debug">         <description>debugging output</description>         <properties read="true" notify="true" />         <value length="20" />     </characteristic> </service>

the android code bluetoothgatt.discoverservices() (that's first time see happen).

and again, have tried resetting bt, restarting nexus, , doing factory reset. also, i've confirmed ble peripheral works expected via desktop app , ios.

i'm on nexus 7, running 5.0.2, , targeting 4.4 in app.

you implementing hack in order call method not made publicly available. don't know modifications have been made method customized firmware.

the hack worked (as in q&a showed), cannot guaranteed work everywhere.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
