Troubleshooting#

Wi-Fi Connectivity problems#

Depending on the manufacturing date your device has one of the following Wi-Fi modules:

  • CC3135 module (latest)

  • CC3100 module

  • Silabs modules (RS9110, RS9113, RS9116)

CC31XX Modules#

Most common error that could appear is:

E: Wifi Error: cannot connect to AP

If you encounter this error please make sure:

  1. Is the entered SSID of the access point correct?

  2. Has the Visionect device gone out of range?

  3. Is the provided password correct?

  4. Does the AP use WPA2-PSK encryption?

  5. Is the AP on a 2.4 GHz bandwidth?

For all the error codes regarding the CC3100 module, please follow the link here.

Silabs Modules#

Note: Due to different Wi-Fi module, the codes below will appear only for Visionect devices manufactured and purchased in the period from 2016 until 2017

0x0003, 0x0019 No AP found#

  • Has the SSID of the access point been entered correctly? Try entering the SSID again.

  • Has your device gone out of range? Try reducing the distance between the device and the access point.

  • Is the provided password correct? Try typing in the password again.

  • Is your access point using WPA2-PSK encryption? Reconfigure your access point if you’re using WEP or WPA.

  • Is the access point on 2.4 GHz band? Visionect Products currently support only 2.4GHz, so you might need to reconfigure your access point.

0x0008 Deauthentication received from AP#

Is the provided password correct? Try typing in the password again.

0x0028,0x0041 PSK length less than 8 bytes or more than 63 bytes, Wrong PSK length#

Is the provided password too long? The password should be 31 characters maximum.

0xFF87, 0xBB38#

Has the device tried to connect to a non-existent TCP server socket? Check if your server can be accessed from the same network your device is connected to.

0xFF9C DHCP handshake failure#

  • Are there enough IP addresses available on the DHCP server? Your device can’t obtain an IP address - perhaps you can extend the DHCP range or configure a static entry for the device.

  • Is your Wi-Fi signal poor? Try moving the device closer to confirm it is not signal related.
