Opermode Parameters#

In rsi_wireless_init() API, configured feature bitmaps are internally processed and sent to firmware. Default configurations (for reference) are available in rsi_wlan_common_config.h. Based on the features required for a specific example, modify the rsi_wlan_config.h provided in the respective example folder. The following configuration parameters are used to configure feature bitmaps.

Disable	Enable	By default this bit value is zero. When `BIT[26] = 0`: For a LTCP socket when maximum clients are connected if a new connection request is received, then this connection request will not be rejected. Instead device will maintain this connection request in LTCP pending list. This request will be served when any of the connected client is disconnected.

Note! 32KHz external clock connection and power save pins

From May 2019, the 32KHz external clock and the power save pins connections changed. To keep software compatibility between initial designs and new designs, there are currently 2 options for connecting the 32KHz external clock and the power save pins:

Option 1 External 32KHz clock connection pins : XTAL_32KHZ_P & XTAL_32KHZ_N Power Save connection pins : HOST_BYP_ULP_WAKEUP & UULP_VBAT_GPIO_3

Option 2 External 32KHz clock connection pin : UULP_VBAT_GPIO_3 Power Save connection pins : HOST_BYP_ULP_WAKEUP & UULP_VBAT_GPIO_0

Option 2 must be used for External 32KHz external clock and Power save connections in new designs.

- In 2.4GHz, USA is configuerd as default country domain and in addition to this, channels 12 and 13 are passively scanned.
- Country inforamtion is updated as per connecting AP's beacon before authentication.
- Upon disconnection with the AP, STA will switch to USA domain along with channels 12 and 13 are passively scanned.
- While doing passive scan (channel 12 and 13) if any beacon is found in that channel STA will switch to active scan.

- If there is no country IE in the beacon of the AP to which STA is going to connect, STA will switch to USA/EU country based on the channel in which the AP exists. For example if the AP in channel between 1 to 11, STA will configure to USA else if the current channel number is 12 or 13 STA will be configured to EU.#
