    change BLE MTU

    hinu_4327176

      Hello,


      Used in combination with WICED-Studio-6.4 (STM32F412 + CYW43438).
      Is it possible to change the MTU size of BLE by modifying the following definition?


        wiced_bt_cfg_settings.gatt_cfg.max_attr_len
                                                         .max_mtu_size


      Thank you.

          Hi hinu_4327176,

           

          You can configure maximum size using GATT settings in wiced_bt_cfg.c. You can try using API wiced_bt_gatt_status_t wiced_bt_gatt_configure_mtu (uint16_t conn_id, uint16_t mtu) to configure ATT MTU for LE operation. Please refer /43xxx_Wi-Fi/libraries/drivers/bluetooth/include/wiced_bt_gatt.h for more info.
