question

Hi, The users need to have multicast enabled on the wifi network. One good way to check. would be to have them use the Fire TV remote app to see if they can see their Fire TV on there, and if they can there shouldn't be any issues with getting fling working. Otherwise, they may need to change their wifi network settings. Thanks, Nick

I don't think multicast is the issue because I launch the same version of the app on all my test phones (4 to 6 depending on what I'm testing) and some will find the Fire TV and some won't. Sometimes they switch, sometimes all find it, sometimes only one finds it, it is very unpredictable.

Hi, What devices and OS are you using on these devices? Also, have you experienced the same discovery issues using the Fire TV Remote control app or the Fling Sample app? Thanks, Nick

I only have one phone which has this issue frequently, the others have it too but rarely. It is a Moto G. Anyways, the FireTV remote app also has the issue. I am using the ConnectSDK and it is able to find the DIAL service of the FireTV but not the Fling service. I will see if I can get one of the sample apps working. I've had a few users also report this issue and I haven't yet found a way to get it to work for them. For example with the Chromecast usually if you reboot your phone, Chromecast and home wifi then it will show up, but that doesn't help with the FireTV.

Just tried the Fling sample app. On my Nexus 5 it found the FireTV really quick. On my Moto G the icon to connect never showed up.

What is the build number and android OS version? Logcat logs, especially from app start would also be very helpful in tracking down this issue. -Nick

My phone that usually has issues is: Moto G 4.4.4 KXB21.14-L1.41 Using Fling SDK 1.1.3 I'll collect logs the next time it doesn't find the Fire TV Stick, it found it fine right now.

Got a chance to capture some logs on my Moto G. 09-22 14:52:15.636 27274-27760/mypackage I/WhisperLink﹕ WPLOG - New log handler set is :com.amazon.whisperlink.platform.GenericAndroidLogHandler@41fb0740 09-22 14:52:16.132 27274-27760/mypackage I/WhisperLink﹕ GenericAndroidPlatform -

Thanks Carlos for the logs. We see from the logs that the discovery process started successfully on your MotoG. It found 2 Android devices on your network. However, it failed to find the Fire TVs on your network. The root cause of that is not immediately clear from the logs - it could be some as yet unknown network issue. This is a tricky problem that we would like to resolve with your help. What will help us greatly is: - Setup a dedicated network for testing your app (e.g. a dedicated router/mobile hotspot) - Convey to us the network setup/topology (Devices in the network, their IP addresses, etc) - Complete logs on the Android device and the Fire TV - Network logs on the Android device, if possible Thanks and Best Regards, Nick

It will probably take me a bit of time before I can setup an isolated network to test this but the other stuff I can probably get quicker. What do you mean by "network logs on the android device"? are you wanting packet captures or something like that?
