regarding connectivity framework

[flicker82]

hi!

im trying to run applications using bluetooth. i do not have any bluetooth cards on my pc, so i just downloaded the nokia connectivity framework 1.1.

i have series 60 sdks already installed, namely: version 1.2 nokia edition, version 2.0 nokia edtion, and version 2.1 for codewarrior. i have already changed the bt.esk of each sdk as follows:
for version 1.2:
hcidllfilename = hci.dll
port = 4
for version 2.0:
hcidllfilename = hci_h4.dll
port = 5
for version 2.1:
hcidllfilename = hci_h4.dll
port = 6

after this, i started the environment (in the nokia connectivity framework), and tried to run a bluetooth application. my problem is that whenever i try to run the multiplayer mode for the version 2.0 emulator, it crashes on me, saying that epoc.exe has performed an illegal operation and will be shutdown. i tried tinkering with the communications>>bluetooth folder in the emulator (i thought that if i switch on the bluetooth for 2.0 emulator, it will all be fine) but again, it crashes!
the version 2.1 emulator, does not crash and i think it works fine.

also, i have recently downloaded series 60 sdk version 2.1 nokia edition. i tried the example BTEnvironment of the connectivity framework. i tried sending a note via bluetooth on the emulator from the 1.2 nokia edition to the 2.1 nokia edition emulator. It says "Cannot establish bluetooth connection". I tried it the other way around (from 2.1 emulator to 1.2 emulator), it also shows the same error. On the connectivity framework, it says "Failed to create connection handle from 000036127B35 to 000034127B35. Another connection handle is already..." What does this mean?


has anybody experienced this? please help. thank you very much.

hi ruchaitu!

sad to say, i haven't found a solution to my problem. i resorted to debugging on the actual devices instead of using the emulator. could you please inform me if you get the chance to resolve this problem? thanks!

I got mine to work just fine! Make sure you do the following:

* Download Setting_Up_And_Using_Bluetooth_HW_With_Development_Tools_v1_1_en.pdf
which is titled "Setting up and using bluetooth hardware with development tools". It looks like they just updated this document this month to work with Series 80 devices as well.

* Then go to section 7 "Setting up the emulator", and follow the instructions *exactly*. It is not enough that you made the changes you mentioned in your post. The port numbers have to match what the connectivity framework sets them to, and you also have to watch out for the fact that there is a "-1" issue with the port settings. For example, if your bluetooth COM port is 5, then you need to put 4 in the bt.esk file.

If you follow all the instructions, it works. I haven't done too much testing, so I don't know how far you can get with the emulator, but at least the BT example applications do work.

Good luck!

hi entell!

i made sure that the port in the bt.esk matched the COM port settings in the connectivity framework. i was able to pair the two devices (test 1 on the "Setting Up" document), but i could not do the test 2, that is sending the note to the other device. The sending device says that it "could not establish a bluetooth connection".

Do you have a bluetooth hardware in your PC? Maybe the reason why i could not test bluetooth connections on the emulator is because i do not have a bluetooth hardware?

I don't have any BT hardware. I am running the NCF on my laptop running WinXP.

I did this last week. I remember running at least a few of the example BT apps and I remember them working, but I didn't try every single one. Maybe not all of them work.

Hi flicker,
i faced the following error on the connectivity framework when i tried to run my own BT program using obex objects,

"Failed to create connection handle from 000036127B35 to 000034127B35. Another connection handle is already..." What does this mean?

now it is working fine, the reason is :
when i opened the connectin for the first time, i need to close it so that i ccan use the connectin later, but if u dont close it gives an error for the next attempt,
(i am a newbee, i am not sure wether this is the right answer are not, i feel this should be).,

one more thing is for ur BT environment to work make sure that
one single bi-directional arrow exists b/w the two emulators
or
2 uni-directional arrows exists b/w the two emulators

refer the connectivity framework for how to connect thses devices.

I am sorry
i have posted some wrong imformation,

>one single bi-directional arrow exists b/w the two emulators
or
>2 uni-directional arrows exists b/w the two emulators

the link which i mentioned in the earlier message need not be present, as a default connection b/w the emulators exists and it works.
