CC2640R2 Central 变成主从一体机

我在multi-role中加了pairing&&bond 的代码部分；

//dev_init
{
// The default passkey if no passcode callback function is registered with
// GAPBondMgr (in GAPBondMgr_Register()). The default in this application
// is to post an SBC_PASSCODE_NEEDED_EVT to the application where it will
// generate a random passcode.
uint32_t passkey = DEFAULT_PASSCODE;
// send a pairing request after connecting; the device waits for the
// application to start pairing
uint8_t pairMode = DEFAULT_PAIRING_MODE;
// use authenticated pairing
uint8_t mitm = DEFAULT_MITM_MODE;
// This is a display only device
uint8_t ioCap = DEFAULT_IO_CAPABILITIES;
// Create a bond during the pairing process
uint8_t bonding = DEFAULT_BONDING_MODE;
GAPBondMgr_SetParameter(GAPBOND_DEFAULT_PASSCODE, sizeof(uint32_t), &passkey);

GAPBondMgr_SetParameter(GAPBOND_PAIRING_MODE, sizeof(uint8_t), &pairMode);
GAPBondMgr_SetParameter(GAPBOND_MITM_PROTECTION, sizeof(uint8_t), &mitm);
GAPBondMgr_SetParameter(GAPBOND_IO_CAPABILITIES, sizeof(uint8_t), &ioCap);
GAPBondMgr_SetParameter(GAPBOND_BONDING_ENABLED, sizeof(uint8_t), &bonding);
}
注册回调也有加上
static gapBondCBs_t SimpleBLECentral_bondCB =
{
(pfnPasscodeCB_t)SimpleBLECentral_passcodeCB, // Passcode callback
SimpleBLECentral_pairStateCB // Pairing / Bonding state Callback
};
现测试连接某个peripheral，发现在multi-role端并没有pairing 事件触发，在 events = Event_pend(syncEvent, Event_Id_NONE, MR_ALL_EVENTS, ICALL_TIMEOUT_FOREVER);没有收到触发事件，而peripheral 是有pairing流程的，只要被连接后，若central端没有绑定，就会发起配对请求；我通过wireshark ，看到peripheral端已经发出配对请求，而multi-role 没有响应。

看下

  uint8_t pairMode = GAPBOND_PAIRING_MODE_INITIATE;

我测试可以自动发起绑定

 /*-----------------CLIENT------------------*/
    // Initialize GATT Client
    VOID GATT_InitClient();

    // Register for GATT local events and ATT Responses pending for transmission
    GATT_RegisterForMsgs(selfEntity);

    // Register to receive incoming ATT Indications/Notifications
    GATT_RegisterForInd(selfEntity);
  }

  // Setup the GAP Bond Manager
  {
    uint8_t pairMode = GAPBOND_PAIRING_MODE_INITIATE;
    uint8_t mitm = TRUE;
    uint8_t ioCap = GAPBOND_IO_CAP_DISPLAY_ONLY;
    uint8_t bonding = TRUE;
    uint8_t replaceBonds = FALSE;

    // Set pairing mode
    GAPBondMgr_SetParameter(GAPBOND_PAIRING_MODE, sizeof(uint8_t), &pairMode);

    // Set authentication requirements
    GAPBondMgr_SetParameter(GAPBOND_MITM_PROTECTION, sizeof(uint8_t), &mitm);

    // Set I/O capabilities
    GAPBondMgr_SetParameter(GAPBOND_IO_CAPABILITIES, sizeof(uint8_t), &ioCap);

    // Set bonding requirements
    GAPBondMgr_SetParameter(GAPBOND_BONDING_ENABLED, sizeof(uint8_t), &bonding);

谢谢！

我的主从一体机中设置pairMode = GAPBOND_PAIRING_MODE_WAIT_FOR_REQ，连接peripheral 后，原peripheral 的pairMode 是GAPBOND_PAIRING_MODE_INITIATE，正常情况下，peripheral 是会主动发起配对的，而我的主从一体机这端没有收到配对请求事件；

而我的主从一体机中设置pairMode = GAPBOND_PAIRING_MODE_INITIATE ，用手机ble app去连接主从一体机，主从一体机是会主动发起配对的，在手机上可以显示配对窗口。

现在就不清楚，为何主从一体机的central角色不能收到配对请求？

我按照你的设置测试可以绑定成功
