I can transfer some Embarcadero builder xe7 examples to my xperia si18 phone with 4.0.4 android version ( api 15 ). Tethering, LOcationDemo, webbrowser ... works well BUT all of the Bluetooth examples doesn't worK. I have tried to select some different "SDK bluetooth permission" on the IDE option, switch on bluetooth on my phone .BUT
a black screen appears or just the firemonkey icon when i launch the application . if i use a new project with a simple button and just add as header : #include and develop on my device, the problem is the same !!!

I would like to realize an Android application that would be able to display an AirPlay, Miracast or Chromecast stream.
This application will be a basic Viewer of these 3 technologies.
I would like that when you launch it, you can see it on your iPhone, Android or Windows Phone or even from computers (PC or Mac). So you can project your screen on an Android.
I've seen some apps on the Play Store that were able to show AirPlay or Google Cast streams but I have not found them for Miracast.
Do you have links to send me SDK of these 3 technologies ?
Thank you all !
I'd like to test apps on device in the same way like on simulator - app runs on real device but I see screen on mac and I can interact with it using mouse. Im just tired of putting phone to my hand all the time. Developing on windows phone allows it, so It would be nice to have it here. Thank you

I just found this. You can control device via mac.
We are users of POS printer Bixolon SPP-R200II which we use for realisation of one of our projects. In the specification of this model it is listed that printer supports printing on iOS devices (iPhone & iPad) but until now we have not succeeded to achieve that. We switch the printer onto iOS mode with a required combination we fonud in official documentation and we got confirmation message. Then we connected to the printer from bluetooth interface inside iPhone Settings app.
After that we tryed to print on this device in various ways - using official test app from AppStore (https://itunes.apple.com/us/app/bixolon-printer-utility/id647125968?mt=8) and using official Bixolon SDK (http://www.bixolon.com/upload/download/software_all_bixolon_printer_sdk_for_ios_v3.1.8.zip) but unfortunately we havent managed to get any result. In this sample apps printer was not even listed as a possible connection point.
Can you direct us in any way to get the printing on iOS devices working? Thank you!
To connect to the SPP-R200II you need to enable MFi Mode for the printer.
Turn on printer
Open the cover and press the power button and paper feed button at the same time for 2 seconds
Close the cover when the buzzer sounds
The printer should now print "iOS mode enable!!" [sic]. If not, you just turned off MFi mode and need to repeat the steps to turn it on again.
Unfortunately the sample application distributed with the Bixolon SDK 3.1.8 is broken and when you press "Lookup/Targeting" nothing will happen. To fix it add this line to didFindPrinter in ViewController.h:
_uiTextFieldAddress.text = [NSString stringWithFormat:#"BT_%#", printer.macAddress];
It should now be possible to connect the printer simply by pressing "Lookup/Targeting" and then "Connect" when you se the Bluetooth address in the text field.
We had the same problem and after contacting technical support, concluded that the model we have is not compatible with iOS, the part number must be 3 letters i, for example SPP-R200IIIK/USA. After making the switch equipment provider, everything works perfectly.
Is the printer paired with the device in settings? It must be paired before the application can interact with it.
I have developed mobile application with Devexpress DXTreme, i need to print that data using bluetooth by a bluetooth printer.
help me, how to print!!!
It is not currently possible to access bluetooth devices with DXTREME out of the box. Instead you can use PhoneGap. Here are some related links from the DevExpress Support Center which is the best place to ask.

I'm trying to use a makey makey (a device based on the Arduino Leonardo) as a keyboard for an iPad. I know that it has already been done, but I'm not able to reproduce it. My guess is that some versions of the iPad don't recognize this device.
Since I can use a USB keyboard and I know that mice are not recognized, I'd like to program the makey makey in such a way that it is "recognized only as a keyboard" (the original device can be used as a mouse and as a keyboard). I'm very new to Arduino, could someone give me a hint please?
A colleague helped me for this issue and we were able to solve it. We just erased this line about CDC:
#define CDC_ENABLED
in the file "USBDesc.h" (in the folder available on github: "firmware/Arduino/hardware/MaKeyMaKey/cores"). After doing this, there is a problem when compiling the code on the device, because the Arduino is not recognized anymore. You can still add your code to the Arduino, but you have to reset the device just after compilation start.
Using the ProMicro 5v and a "Case Logic 2.0 USB Hub" and the Camera kit I was able to get the programed keyboard commands to be recognized by the iPad without modifying "USBDesc.h" file.
ProMicro has built in HID emulation support very similar to Arduino Leonardo. Besides the "USB IO Board: The connected device is not supported" error, the device is apparently unofficially supported. I believe this has something to do with the hub.
In my arduino code I am using the "Keyboard_ascii.h" library and am using Keyboard.print, and Keyboard.write commands to send the key commands / text to the iPad.
