CC2541如何减少收发连接间隔?  要修改哪些参数?

  • 这些参数里应该改哪些? 尝试改过 DEFAULT_DESIRED_MIN_CONN_INTERVAL ,但通过示波器观察,发送间隔并没有改变。

    // What is the advertising interval when device is discoverable (units of 625us, 160=100ms)
    #define DEFAULT_ADVERTISING_INTERVAL 160

    // General discoverable mode advertises indefinitely,origin GAP_ADTYPE_FLAGS_LIMITED
    #define DEFAULT_DISCOVERABLE_MODE GAP_ADTYPE_FLAGS_GENERAL

    // Minimum connection interval (units of 1.25ms, 80=100ms) if automatic parameter update request is enabled
    #define DEFAULT_DESIRED_MIN_CONN_INTERVAL 80

    // Maximum connection interval (units of 1.25ms, 800=1000ms) if automatic parameter update request is enabled
    #define DEFAULT_DESIRED_MAX_CONN_INTERVAL 800

    // Slave latency to use if automatic parameter update request is enabled
    #define DEFAULT_DESIRED_SLAVE_LATENCY 0

    // Supervision timeout value (units of 10ms, 1000=10s) if automatic parameter update request is enabled
    #define DEFAULT_DESIRED_CONN_TIMEOUT 1000

    // Whether to enable automatic parameter update request when a connection is formed
    #define DEFAULT_ENABLE_UPDATE_REQUEST FALSE

    // Connection Pause Peripheral time value (in seconds)
    #define DEFAULT_CONN_PAUSE_PERIPHERAL 8

    // Company Identifier: Texas Instruments Inc. (13)
    #define TI_COMPANY_ID 0x000D

    #define INVALID_CONNHANDLE 0xFFFF

  • 您指的是connection interval?

    您可以参考下论坛之前的帖子 http://www.deyisupport.com/question_answer/wireless_connectivity/bluetooth/f/103/t/18625.aspx

    希望对您有所帮助。

  • 这个参数是跟功耗紧密关联的,如果对功耗有更高的要求,推荐 TI 的新一代 BLE 产品 CC2640。
