Wi-Fi Error Codes

If your Joan device is having trouble connecting to the Wi-Fi network, pairing it with your computer and running the Joan Configurator might give some insight as to what is exactly the issue in the form of an Error Code.

Joan 6 Error codes (CC3100 module)

Note: Newer Joan 6 models have CC3100 modules from Texas Instruments.

Most common error that could appear is:

E: Wifi Error: cannot connect to AP

If you encounter this error please makes sure:

Is the entered SSID of the access point correct?
Has the Joan device gone out of range?
Is the provided password correct?
Does the AP use WPA2-PSK encryption?
Is the AP on a 2.4 GHz bandwidth?

Joan 6 Error codes (Raspberry Pi modules)

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

The following list contains all the possible Error Codes that can appear in the Joan Configurator as well as a brief description of what they mean.

There are certain issues, such as Error Codes 0x0003, 0x0019, 0x0029, and 0x0041, which you can resolve on your own. Just make sure that your network meets the requirements of our Joan devices, the Wi-Fi information you provided is correct, etc.

Also, make sure to check out the most frequent causes of Wi-Fi connectivity problems in this article, where we also give tips on how to resolve them.

For other issues, we ask you to contact us at support@getjoan.com, let us know which code appears and we will do our best to help you resolve it.
