Hi,
Since there hasn't been no response to the original thread(https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/785065), I created a new thread. The problem description is found in the original thread.
This is my workaround. I modified gapBondMgr_SupportsCentAddrRes() as follows:

static uint8_t gapBondMgr_SupportsCentAddrRes(uint8_t *pPeerAddr, GAP_Peer_Addr_Types_t addrType) { uint8_t idx; // Check for valid input address if(pPeerAddr == NULL) { return FALSE; } // Try to find this device in the resolving list to see if an RPA will be // used if(MAP_LL_PRIV_FindPeerInRL(resolvingList, addrType, pPeerAddr) != INVALID_RESOLVE_LIST_INDEX) { // Device was found with a valid IRK. If the IRK is not all zeros, // RPA will be used. So, check to see if the device supports central address // resolution (i.e. it has the CAR char). // First, find the bonding table index: if(GAPBondMgr_FindAddr(pPeerAddr, addrType, &idx, NULL, NULL) == SUCCESS) { // Read the IRK from NV uint8_t tempIRK[KEYLEN]; osal_snv_read(DEV_IRK_NV_ID(idx), KEYLEN, tempIRK); // Check if the device has CAR enabled or the IRK is all zeros if((gapBondMgrGetStateFlags(idx) & GAP_BONDED_STATE_CAR) || osal_isbufset(tempIRK, 0x00, KEYLEN)) { // Device has CAR enabled or doesn't have to have it, // so OK to use RPA or IDA return TRUE; } else { // Device doesn't have CAR enabled so can't use RPA return FALSE; } } else { // Device wasn't found in bonding table. This means that the device was // manually added to the resolving list by the application and it is the // application's responsibility to check the CAR. return TRUE; } } else { // An RPA won't be used so no need to check for CAR char return TRUE; } } |
The workaround works on a TI Peripheral which is trying directed advertising towards TI Central initialized with ADDRMODE_PUBLIC and paired with the TI Peripheral.
Can somebody from TI please confirm if the idea makes sense?
