Verifying the scaner's identity

Yes, I can see that the example stores the data of the previously paired device. But, my question is how these data can be checked on the scan request where we only have the address of the scanner?

Hello there,

In order to increase the quality of service, we want to trigger an event once a paired user sends a scan request. In other words, we don't want to block scanning from other devices, we only need to be notified once a paired device has sent a scan request.
The following code is what I'm using for this purpose but I'm not sure if this is the right method. (especiallly for legacy pairing)

bool user_check_bonding(struct bd_addr peer_addr, uint8_t addr_type) { const struct app_sec_bond_data_env_tag *pbd = NULL; uint8_t bdaddr_type; // Check if peer's BD address is public or random static bdaddr_type = app_get_address_type(addr_type, peer_addr); if ((bdaddr_type == APP_PUBLIC_ADDR_TYPE) || (bdaddr_type == APP_RANDOM_STATIC_ADDR_TYPE) || (bdaddr_type == APP_ID_ADDR_TYPE)) { if (bdaddr_type == APP_ID_ADDR_TYPE) { // Search DB by peer's BD address pbd = app_easy_security_bdb_search_entry(SEARCH_BY_ID_TYPE, (void *) peer_addr.addr, BD_ADDR_LEN); } else { // Search DB by peer's BD address pbd = app_easy_security_bdb_search_entry(SEARCH_BY_BDA_TYPE, (void *) peer_addr.addr, BD_ADDR_LEN); } // If peer has been found in DB if(pbd) { // Store device bond data to security environmen // Accept encryption return true; } // If peer has not been found in DB else { // Reject encryption, disconnect return false; } } // Check if peer's BD address is Resolvable Private Address else if (bdaddr_type == APP_RANDOM_PRIVATE_RESOLV_ADDR_TYPE) { // Start BD address resolving procedure if(!user_app_easy_security_resolve_bdaddr(peer_addr)) { return false; } return true; } // Check if peer's BD address is non-Resolvable Private Address else { // Reject encryption, disconnect return false; } }

Do you think this would cover all the cases of pairing (we might have to change the pairing methods and security level and therefore I want this function to be more generic)?

Ok, now I'm able to search for the device but I have a new issue. How can I identify the scanner's address type?
