I am investigating Android Wifi Direct and Network Discovery.
I have followed the Google Android examples and come to the same conclusion on both implementations.
They are completely and utterly Unreliable.
I have followed this training tutorial https://developer.android.com/training/connect-devices-wirelessly/wifi-direct.html
WiFi Direct issues.
My call to
mManager.discoverPeers(mChannel, new WifiP2pManager.ActionListener()
ALWAYS returns success
however my Broadcast receiver either doesn't receive
WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION
at all
or when it does receive WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION the peer list is alway empty (e.g size() = 0).
I have four Android devices available to be "discovered"
and very rarely some of them are discovered.
The link I have shared seems pretty basic and simple to follow. I have passed listeners to all possible method calls and have never seen I fail error log.
What is the secret to developing a reliable WiFiDirect Android application.
The code I have developed matches EXACTLY that documented in the above link.
What debugging tools can I use to identify what my issue(s) are/is?
