This section explains how to set and retrieve the country code for a Wi-Fi device. The
            country code is used to determine the available Wi-Fi channels.

## Setting the country code

Use the following function to set the country code:

    int wifi_mgmr_set_country_code(char *country_code);Copy to clipboard

Function parameter
- `country_code`: A pointer to a string representing the country
                    code.

## Retrieving the country code

Use the following function to retrieve the currently set country code:

    int wifi_mgmr_get_country_code(char *country_code);Copy to clipboard

Function parameter
- `country_code`: A character array with enough space to receive
                    the current country code.

## Supported country codes

When setting the country code for a Wi-Fi device, it is important to note the range
                of country codes supported by the current API. The country code is primarily used to
                determine the number of available Wi-Fi channels for the device in different
                countries or regions. Here are some supported country codes and their corresponding
                channel numbers.

## List of country codes

| Country code | Number of channels |
| :---: | :---: |
| CN | 13 |
| JP | 14 |
