Bluetooth and MIDP-2.0 compatibility?

Hi
I'm very new with Java ME Platform SDK 3.0.
It is also possible develop bluetooth application using MIDP-2.0 and
CLDC-1.1 or only for MIDP-2.1?
I read http://developers.sun.com/mobility/apis/articles/bluetoothintro
but I don't know the compatibility of them.

Hi.
If you read the JSR-82 specification you find out that the Bluetooth doesn't depend on any version of MIDP.
Check here: [http://www.jcp.org/en/jsr/summary?id=82|http://www.jcp.org/en/jsr/summary?id=82] - it's chapter 3.3.2 in latest final revision.

Great problem with bluetooth and MIDP devices

Hello all,
I'm making a client/server application with bluetooth JSR82 Serial Port Profile (SPP). The clients are mobile phones (J2ME application) that want to get informations from a server (J2SE application) that publishes a service.
My system works well with Sun Wireless Toolkit: it works fine also if I try to start a lot of servers and a lot of clients and a lot of other bluetooth device.
When I install it on actual environment like a personal computer with BlueCove stack and mobile phone like Nokia 6600 it works ONLY if there are 1 client and 1 server.
The problem is that the mobile phone doesn't find the server if there are other Bluetooth devices enabled!!!
I've made a lot of changes in my code but it don't work!
At first my client application works in this way:
1) start finding Bluetooth devices
2) a device found -> start finding services on this device
3) a server service is found -> stop device inquiry and connect to the server
4) else client continues to search devices and iterates like above
This solution works WELL on Sun toolkit but not on Nokia 6600 and Bluecove. So i changed it in this way:
1) start finding all bluetooth devices
2) after device inquiry stops:
3a) start finding all services on first device found... waiting for end
3b) start finding all services on seconddevice found... waiting for end
3x) ....
4) connect to the first service found
Also this solution doesn't work with Nokia 6600 and BlueCove!!!!!!!
I'm getting crazy!!!
Thanks,
Renato
ps Sorry for my English...

Hi guys, Im new here and its the first time i get to develop something using J2ME and J2SE toogether via bluetooth! You seem to be more expert than me so i was wandering if you could help me with some literature or even with some code.
I even tryed BlueCove but Im having some trouble! Please help me!!!

MIDP/CLDC Device Compatibility...

Hello everyone,
I am performing some research on the compatibility of MIDP/CLDC and current devices. It is a well known fact that some applications (MIDlets) will operate fine on some devices, while other devices require 'tweaking'.
Mikko Konito (writting for IBM) says "manufacturers often deviate from the [MIDP] profile" (link: http://www.ibm.com/developerworks/wireless/library/wi-design.html) which explains why these tweaks are necessary.
I would like to hear your views on what else could cause such "incopatibilities" with mobile devices and MIDP.
Many thanks,
P.M

Hi,
I worked about 5 years in J2ME development and porting. From the beginning of J2ME (MIDP-1.0 and beginning of MIDP-2.0) porting was a great business - every manufacturer and almost every handset type was different in many aspects.
Now the situation is a little bit better and also handset manufacturers are more responsible for their work.
But still - you must care:
- different display sizes
- different media capability (sound formats)
- diferent sets of API implementations
- ...and different BUGS in the MIDP implementation!
While the basic MIDP was implemented poorly at the beginning, now it seems that the MIDP itslef is implemented well on most of the new handsets, however the situation repeats with various new and non standard APIs (PIM, M3G...).
Simply - it's always good to test particular application on particular handset to be sure...

Addressbook Bluetooth and iSync - Get numbers off phone to AB

Greetings,
There were many topics on this after a search but I couldn't find an answer I could understand. Forgive me if I am a little slow.
I plan to buy the iPhone here in the next few days. My old Motorola RAZR V3 has bluetooth and works flawless by syncing AB with the phone by using iSync. However, none of the phone numbers from my phone (Which weren't in AB before) end up in my AB. Am I doing something wrong here?
I never used any type of sync before since I didn't need a media device but now I guess I do? Apparently iPhone has a new built in SIM card and I can't transfer my numbers if I don't do this?
Thanks.. Oh... What is really the difference between iSync and the Sync in addressbook? Everytime I click the bluetooth icon in AB it asks to pair then nothing happens?
//Cheers

That happens if you've got your contacts stored on your SIM card in the RAZR. Transfer them to your phone, then they'll magically appear in address book. I've found as well that for some reason the bluetooth pairing in address book doesn't do much, iSync does though.

TS3048 Bluetooth and USB ports aren't working can't connect mouse or keyboard.

Bluetooth and USB ports aren't working, so am unable to use Imac past turning it on. There's no way to connect mouse or keyboard, it started right after a software update for Maverick (OS X bash Update 1.0 – OS X Mavericks), bluetooth symbol not showing in the task bar at all.

Hi SBrwn,
Thanks for visiting Apple Support Communities.
The symptom you're describing can be frustrating to troubleshoot as our options are limited. I do suggest resetting the System Management Controller (SMC) if you have not already. This step can help you regain use of USB and Bluetooth.
Follow these steps to reset the SMC on your iMac:
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer. [by holding down the power button]
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
You can find these steps and more information at this link:
Intel-based Macs: Resetting the System Management Controller (SMC)
All the best,
Jeremy

TS3280 How can i enable both paired bluetooth and ios keyboard input at the same time?

How can i enable both paired bluetooth and ios keyboard input at the same time?
This is needed for the app im working on. Need some user input via keypad as well as scanner input via a paired bluetooth scanner.

You probably should not be using a keyboard bluetooth profile for a scanner, I am not a developer for apple so do not know the location for you to find out the correct profile you should be using for an input device that is not a keyboard. Sorry,
I am sure if you navigate the apple developer site you will probaly finmd what you're looking for.

Short-sighted approach to Bluetooth and Wi-fi.

I've just bought an Ipad - which I think is a truly amazing bit of kit. However within 36 hours I've discovered some very basic shortcomings in the software design in respect to both Bluetooth and Wi-fi. I was so shocked at their absence that I ran these past the Apple Support team who confirmed my worst fears.
The Ipad Bluetooth will not work with my Blackberry 9000. The Blackberry pairs with the Ipad but the Ipad syncs with nothing. Given that Blackberries are probably the most used smartphone in the business community - this seems like a really serious oversight?
Wi-fi printing I'm told only works with Airprint 101 - but then is limited to a narrow range of HP printers. Why? I have an HP Photosmart 3310 which is wireless and can accept wireless connectivity from any Windows based PC. I did evetually find a messy solution to the problem which I'll detail because I'm sure there are clever enough people working at Apple who might just be able to fix it better!!
You need to create a directory in the Programs Directory called 'Airprint'. You then need to download the three files that Airprint 101 uses and locate these in the directory. As soon as you rum 'Airprint.exe' your Ipad will show you any printers that are attached through wi-fi. However you must keep the directory with the Airprint files open because as soon as you close it - the printers disappear.
I improved the situation slightly by creating a task in the Task Sceduler to run when the PC opens and which automatically runs the 'Airprint.exe' file. Now all I have to do is to ensure that my Windows PC is on befire I use my Ipad!!
There has to be a better way than this and I feel it detracts from the Ipad as a potentially super piece of kit.
Perhaps someone from Apple would like to look into this and give some feedbasck? Thanks.

No. It doesn't work with any cell phones.
The iPad Bluetooth works with only with headphones and keyboards.
Wi-fi printing I'm told only works with Airprint 101
Dunno what *AirPrint 101* is. AirPrint was incoporated into iOS 4.2.1
but then is limited to a narrow range of HP printers. Why?
Besause printer manufacturers have not updated their printer firmware to speak "AirPrint". It is up to them to make their printers compatible, not he other way around.
You need to create a directory in the Programs Directory called 'Airprint'. >You then need to download the three files that Airprint 101 uses and locate these in the directory. As soon as you rum 'Airprint.exe' your Ipad will show you any printers that are attached through wi-fi.
This has nothing to do with Apple. It's somebody hack to get iPads to print through a computer.
AirPrint does not talk through a computer.
It talks directly to the printer on the network.

I have a dv4-2180us and I want to change out the wifi card for one w/ bluetooth and 5G

Product name dv4-2180US. My wifi card is intel wifi link 1000 BGB, and I'd like to switch it out to an intel 6230 that has both. Is it possible to modify the BIOS? I have upgraded my BIOS to the most recent 55454 hoping that would correct the problems with the keyboard...which it has not...but I'm far more interested in making full use of my network., Thanks.

I can tell you that you need to make sure the form factor is the same on the new as the existing one.
The bios really has no bearing on it. Its hardware thats compatible with hardware.
Parts like that are not readily available to swap from machine to machine. There are standards for which the card interfaces to the machine and thats why I mentioned the form factor of the card.
Physical dimensions are also to be noted, as some cards are larger than others with the same form factor.
You really have to do your homework and research to see what will work.
Your machine may already have a slot availble for a bluetooth board, or fingerprint reader as those are both viable options.
You are not likely going to get bluetooth and wireless n on the same card anyways. I would suggest looking for a dual band wireless n card and seeing if you have another slot to put a blutooth module into.
Another option is to get a type 2 cardslot module and just insert it when you need it. If your machine has this type of external cardslot it may be your cheapest option.

I have a problem with my Iphone 4s since I did my first update at your Itunes, the bluetooth and the WiFi it is not workinhg anymore.
It is sad that companies like apple are not able to support thier sofware and business.
I went to a apple store at South Park, Charlotte NC,
and found out the worst customer service (in my case)
They don't have answers and don't understand about "dont let any customer go away sad or mad"
I explain to them that I did everything they said to fix the problem, even to dounload the iOS 6.1.3
that was supposed to fix the problem.
they said fix the problem in other phones but not in mine.
So here I am with no wifi and bluetooth, with apple technicians and experts that don't know what to do with the problem that the sofware they developed cause in my iphone 4s.
and the solution is for me to pay $199.00 US dollars for a problem that I did not cause.
wich means to buy something else from apple to fix a problem that it is not my fault.
Great! what a convenient solution.
I would like to have an answer from you guys and see if someone there have a better answer for me that shows support, values and integrity as a grest company with solutions for your customers.
Dont think that I want a new phone, I want mine fixed if is possible.
Thank you very much and God Bless you!

Apple isnt here. this is a user based forum for technical questions. The solution is to restart, reset, and restore as new which is in the manual after that get it replaced for hard ware failure. if your within your one year warranty its replaced if it is out of the warranty then it is 199$

Not working WI-FI, Bluetooth and quickly discharged battery on my iPhone 4S. Не працює Wi-Fi, Bluetooth і швидко розряджається батарея на моєму iPhone 4S.

Not working WI-FI, Bluetooth and quickly discharged battery on my iPhone 4S (MD234 / A).Switcher WI-FI is not active(gray color), Bluetooth always search(badge"network activity") and total time to completely discharge the battery is about 4-6 hours.
I'm trying to cast network configuring, reset all settings, erase all content and settings and nothing helped. I also tried to restore the iPhone, restore from backup, restore DFU mode and also nothing helped. My iPhone does not fall, not shock and not get water.
The problems started after updating to IOS 6.1.3. In all previous firmware it worked good.
I never put Jailbreak! And I buy his new!
Updates to IOS 7 will fix all the problems?

Проблеми почалися після оновлення до IOS 6.1.3. На всіх попередніх прошивках він працював добре.

Hello Everyone, I just bought a HP Photosmart Premium All-in-One Printer - C309g but i find it very difficult to connect to it via BLUETOOTH and WIRELESS on my IPAD 3...i will be very greatfull if i'll get a solution as soon as possible. Thanks

Hi Tomiwa,
You cannot print from the iPad to that printer. AirPrint and Bluetooth are completely different.
There may be apps you can buy that will enable using that printer, but that is not an ideal solution.
That particular printer has had many bad reviews, and is unreasonably expensive for its features. Considering that you just bought the printer, as well as its lack of AirPrint, I suggest you return it and buy a printer that supports AirPrint.

Intel iMac; upgraded adobe flash; bluetooth keyboard no longer pairs but magic mouse still OK. With Bluetooth switched on the screen splits into 4 areas and open windows seperate and shrink. Switch off Bluetooth and problem disappears and iMac works OK

Intel iMac; upgraded adobe flash; bluetooth keyboard no longer pairs but magic mouse still OK. With Bluetooth switched on the screen splits into 4 areas and open windows seperate and shrink. Switch off Bluetooth and problem disappears and iMac works OK with plug-in keyboard and mouse

Hi, Derek -
...the screen splits into 4 areas and open windows seperate and shrink.
Sounds like Spaces is being activated somehow. With the wired keyboard and mouse in use, select the Exposé & Spaces control pane in System Preferences, click the choice in that pane for Spaces. See what the settings are. There are some activation settings in that pane - by default, F8 activates it.
It could be that the bluetooth keyboard has some stuck keys and is activating Spaces; or that the activation command has somehow been reset to something that the bluetooth mouse, or bluetooth itself, is triggering.

IOS 7.0.4 iPhone4s Bluetooth and WiFi "Off" but Bluetooth spinning

As title mentions, I have an iPhone 4S, running iOS 7.0.4 (the latest as of this writing).
After a holiday trip to Mass., my bluetooth and wifi won't turn back on. The settings screen shows Airplane mode Off (switch), WiFi Off (word), Bluetooth Off (word).
When I tap on Bluetooth, instead of seeing the switch, I have a spinner. It says "location accuracy and nearby services are improved when Bluetooth is turned on." and nothing else on the screen...
Soft reset, hard reset, reset network settings, backup and restore, so far none of these processes have helped. Neither has reactivating airplane mode, using the pop-up control center (it will light up the bluetooth B and say "bluetooth: on", but when I visually check on settings, it still says "off" and has the spinner instead of switch). I've even tried things like rebooting the phone with airplane mode on to see if that would help.
Due to bluetooth being down, the WiFi switch on it's second screen under settings is disabled and will not activate, even though the pop-up control panel will report the activation of WiFi as well just like it does bluetooth...
About phone will give me a hex bluetooth address, but wifi address is "N/A". The one time I found the diagnostics logs, I found a bunch of "bluetooth crashed" messages, cannot find them as of this writing again...
Not sure if this has any influence or not, but while I was in MA, at my mom's house who has a very old router, I used my iPad mini to do a Facetime call, and during said call my phone was "ringing" like it wanted to take the call, but I ignored it. WiFi seemed functional at my mom's house, my nephew had no problem playing angry birds before I left, but I didn't do anything else but imessage my wife and make a phone call at the airport until I landed in St. Louis, where I found the bluetooth non-functional. iPad is, as of this writing, still fully functional.

I have experienced the same problem and tackled the solutions in very much the same way but to no avail. Can anyone help as this is very annoying.
