Troubleshooting Wi-Fi Issues
- ADB command line Utility (Instructions)
Unable to connect to a Wi-Fi network
The Wi-Fi passphrase for your local Wi-fi network cannot have spaces (even at the end of the passphrase string), or the camera will be unable to connect to the Wi-Fi network.
Display the hardware MAC address
Use the ADB command line
adb shell ifconfig wlan0
and look for HWaddr in the output. The MAC address will be in a format similar to: 00:0A:G5:5B:20:9E
Display the assigned IP address
Use the ADB command line
adb shell ifconfig wlan0
Obtain the Wi-Fi access point passphrase
The Vision AI Dev Kit camera hardware should have a unique Wi-Fi access point passphrase found on a sticker on the bottom of the device. If there is no sticker, use the ADB command line
adb shell cat /data/misc/wifi/hostapd_virtual.conf
to display the access point configuration details. The output will be similar to this
> ctrl_interface=/var/run/hostapd
> interface=softap0
> #driver=nl80211
> #ieee80211d=1
> ieee80211n=1
> hw_mode=g<br/>
> country_code=US
> ssid=MSIoT_E72FA8
> macaddr_acl=0
> channel=0
> wpa=2
--- > wpa_passphrase=NhEtVE3D ---
> wpa_key_mgmt=WPA-PSK
> #wpa_pairwise=CCMP
> rsn_pairwise=TKIP CCMP
> ht_capab=HT20 SHORT-GI-20
> wmm_enabled=1
> ignore_broadcast_ssid=0
The line marked with three dashes above contains the passphrase, which is unique to each device.
Changing the configured Wi-Fi network
To change the Wi-Fi network your DevKit hardware connects to, long press the power button for 5 seconds to turn on the DevKit hardware access point. Connect your PC to the Wi-Fi access point by running the Configure the DevKit process again, using the new Wi-Fi network settings.
