F.2 Commands

bStatus_t GAPBondMgr_SetParameter(uint16 param, void *pValue)

Set a GAP Bond Manager parameter.
Parameters

param – Profile parameter ID (see Section F.3)

len – length of data to write

pValue – pointer to value to set parameter. This depends on the parameter ID and is cast to the appropriate data type

Returns

SUCCESS: parameter was set

INVALIDPARAMETER: param was not valid

bleInvalidRange: len is not valid for the given param

bStatus_t GAPBondMgr_GetParameter(uint16 param, void *pValue)

Get a GAP Bond Manager parameter.
Parameters

param – Profile parameter ID (see Section F.3

pValue – pointer to a location to get the value. This pointer depends on the param ID and is cast to the appropriate data type.

Returns

SUCCESS: param was successfully placed in pValue

INVALIDPARAMETER: param was not valid

bStatus_t GAPBondMgr_LinkEst(uint8 addrType, uint8 *pDevAddr, uint16 connHandle, uint8 role)

Notify the Bond Manager that a connection has been made.
Parameters

addrType – address type of the peer device:

peerAddr – peer device address

connHandle – connection handle

role – master or slave role

Returns

SUCCESS: GAPBondMgr was notified of link establishment

void GAPBondMgr_LinkTerm(uint16 connHandle)

Notify the Bond Manager that a connection has been terminated.
Parameters

connHandle – connection handle

void GAPBondMgr_SlaveReqSecurity(uint16 connHandle)

Notify the Bond Manager that a Slave Security Request is received.
Parameters

connHandle – connection handle

uint8 GAPBondMgr_ResolveAddr(uint8 addrType, uint8 *pDevAddr, uint8 *pResolvedAddr)

Resolve an address from bonding information.
Parameters

addrType – address type of the peer device:

peerAddr – peer device address

pResolvedAddr – pointer to buffer to put the resolved address

Returns

Bonding index (0 – (GAP_BONDINGS_MAX-1): if address was found...

GAP_BONDINGS_MAX: if address was not found

bStatus_t GAPBondMgr_ServiceChangeInd(uint16 connectionHandle, uint8 setParam )

Set/clear the service change indication in a bond record.
Parameters

connHandle – connection handle of the connected device or 0xFFFF for devices in database.

setParam – TRUE to set the service change indication, FALSE to clear it.

Returns

SUCCESS – bond record found and changed

bleNoResources – no bond records found (for 0xFFFF connHandle)

bleNotConnected – connection with connHandle is invalid

bStatus_t GAPBondMgr_UpdateCharCfg(uint16 connectionHandle, uint16 attrHandle, uint16 value )

Update the Characteristic Configuration in a bond record.
Parameters

connectionHandle – connection handle of the connected device or 0xFFFF for all devices in database.

attrHandle – attribute handle

value – characteristic configuration value

Returns

SUCCESS – bond record found and changed

bleNoResources – no bond records found (for 0xFFFF connectionHandle)

bleNotConnected – connection with connectionHandle is invalid

void GAPBondMgr_Register(gapBondCBs_t *pCB)

Register callback functions with the bond manager.
Parameters

pCB – pointer to callback function structure (see Section F.4)

bStatus_t GAPBondMgr_PasscodeRsp(uint16 connectionHandle, uint8 status, uint32 passcode)

Respond to a passcode request and update the passcode if possible.
Parameters

connectionHandle – connection handle of the connected device or 0xFFFF for all devices in database.

status – SUCCESS if passcode is available, otherwise, see SMP_PAIRING_FAILED_DEFINES in gapbondmgr.h

passcode – integer value containing the passcode

Returns

SUCCESS: connection found and passcode was changed

bleIncorrectMode: connectionHandle connection not found or pairing has not started

INVALIDPARAMETER: passcode is out of range

bleMemAllocError: heap is out of memory

uint8 GAPBondMgr_ProcessGAPMsg(gapEventHdr_t *pMsg)

This is a bypass mechanism to let the bond manager process GAP messages.
Note

NOTE

This bypass mechanism is an advanced feature and should not be called unless the normal GAP Bond Manager task ID registration is overridden.
Parameters

pMsg – GAP event message

Returns

TRUE: safe to deallocate incoming GAP message

FALSE: not safe to deallocate an incoming gap message

uint8 GAPBondMgr_CheckNVLen(uint8 id, uint8 len )

This function will check the length of a Bond Manager NV Item.
Parameters

id – NV ID

len – lengths in bytes of item.

Returns

SUCCESS: NV item is the correct length

FAILURE: NV item is an incorrect length
