Wi-Fi direct return to NULL


Hi all~

I have a problem about wi-fi direct. 

Now, I developing native app using wi-fi direct.

I use ' Tizen::Net::Wifi::WifiDirectDeviceManager::GetWifiDirectDeviceN() ' namespace.

However, I using that, I receive only NULL.

NULL is error mean. But I don't know cause. Please let me know.

Below included screen shot.

My development environment is RD-QP device. And I reference to Wi-Fi Direct sample app in SDK 2.2.1

Thank you for your concern :)

Hi,
You can check the following:
1. The specific error code can be accessed using the GetLastResult() method. 
2. Check whether the feature is supported by Tizen::System::SystemInfo::GetValue(const Tizen::Base::String&, bool&).

Hi, just fyi:
I was able to get valid pointer (on RD-QP device) this way in Native example->WifiDirectChat.

Really?

What is your develop condition?

Ubuntu? Windows? and SDK 2.2.1? Native app? Web app? 

Please tell me detail.

I have two RD-PQ devices. However I get to fail all devices when run as WifiDirectChat app.

Really is that sample a WifiDirectChat? So then, If you send to me your project and *.tpk package file?

I don't konw why I get Null pointer from all devices.

Thank you.

Hi,
I have checked with WifiDirChat on M0 (RD-PQ) and on M1 devices and just have added code in MainForm::Initialize to get logs:

result r;
WifiDirectDevice* pWifiDirectLocalDevice1 =null;
pWifiDirectLocalDevice1=WifiDirectDeviceManager::GetWifiDirectDeviceN();
AppLog("pWifiDirectLocalDevice1=%d",pWifiDirectLocalDevice1);
r = GetLastResult();
AppLog("_Result=%s",GetErrorMessage(r));

It was ok.
Do you have interrnet connection? Is wi-fi working? maybe you have not installed wlan driver on M0.
Alexey.

Hi,

Yes, I tried that all. And I checked internet connection. Wi-Fi working is success of course.

However.. I First hear about wlan driver. If you tell me detail?

Where I download the wlan driver?

 

Thank you.

Alex Dem

Hi,
If you have flashed 'M0 device' firmware by himself you should install this driver (wlan and other) after 'M0 binary'.
But if you have working wifi and access to internet , it mean that it is installed already.

Hi,

Thank you for your comment.

If you check the your devices model name?

My devices model name is GT-I9300.

Hi,
My M0 device is GT-i9300 too. My firmware is 2.2.1 (Settings->About phone->Version) latest for M0.
