Hi,
File '/20719-B1_Bluetooth/include/20719/stack/hcidefs.h' contains the "LE features encoding" settings:
/* Data length extension: bit 5 */
#define HCI_LE_FEATURE_DATA_LEN_EXT_MASK 0x20
#define HCI_LE_FEATURE_DATA_LEN_EXT_OFF 0
#define HCI_LE_DATA_LEN_EXT_SUPPORTED(x) ((x)[HCI_LE_FEATURE_DATA_LEN_EXT_OFF] & HCI_LE_FEATURE_DATA_LEN_EXT_MASK)
I think this are the flags controlling whether to enable DLE or not.
When and where to set the exact PDU payload size?
Is thers any sample about CYW20791 DLE?
Best regards.

Please check the parameter .max_mtu_size in the wiced_bt_cfg.c.
And then use the API wiced_bt_gatt_configure_mtu to configure the MTU size after connection.

As the document "CYW20719: Execute-in-Place (XIP) Application Support Guide" says, please configure the ConfigDSLocation based on the APP XIP Size. Then addd APP_XIP=1 to enable the XIP function.
