I've been trying to configure WiFi networks which require EAP Authentication and Identify Certs on some TC70 and MC40 devices. I have been met with mixed results so far and cryptic errors from Android's WifiStateMachine. I need some help in understanding these log messages and come to a possible resolution for why these devices are behaving the way they are.
 
Network Name: FLQA NPS FOREST32 WPA
 
Device: MC40OS Version: 4.4Behavior: After setting up the WiFi network along with required certificates, connecting to network initially failed but was successful later on.
Logs: Attached, mc40_4.4.txt
 
Device: TC70
OS Version: 6.0.1
Behavior: After setting up the network along with required certificates, device immediately connected successfully.
Logs: Attached, tc70_6.0.txt
 
Device: TC70
OS Version: 5.1.1
Behavior: After setting up the network along with required certificates, the device was always unsuccessful in connecting to the network.
Logs: tc70_5.1.1.txt
 
The common recurring error in all unsuccessful scenarios is
07-07 10:50:16.368 990-990/? I/wpa_supplicant: wlan0: Trying to associate with SSID 'FLQA NPS FOREST32 WPA' 07-07 10:50:16.402 575-803/? E/WifiStateMachine: Error! unhandled message{ when=-33ms what=131221 arg1=2225 obj=FLQA NPS FOREST32 WPA target=com.android.internal.util.StateMachine$SmHandler }
This error is an internal Android error which prevents the device from connecting. To rule out a possible network issue we tried connecting to this network under identical conditions from other Android devices and they could connect successfully in the first try.
 
It would be great if someone from the Zebra team could help me understand these logs better and possibly come to a resolution for this issue. Thanks!
