8.1 Setup and Configuration

Operating AP on DFS channel is done with the ‘user-scripts’ provided by TI. These scripts can be used as a reference of how to operate the AP DFS Master feature, and their usage is described below:

Note: These scripts are used also for running AP on non DFS channel as well.

The configuration parameters of the hostapd are located in a configuration file ‘hostapd.conf’. These files are provided by TI and may be modified to meet the product requirements. However, there are some parameters needed to be modified in order to support AP DFS Master, as mentioned in Table 8-1, and these parameters must be set in order for the feature to function correctly.

Table 8-1 Hostapd.conf File Parameters to Support DFS
Attribute/File hostapd.conf Comments
hw_mode a DFS is operational on A band only
country_code Pick a country For example: US
channel Pick channel according to the HW mode and the country code selected Channel must be supported in the selected country
