Reading MAC address

[Atul Bansal]

Hello

I just have some small queries.

Let's say that I am scanning continuously for advertisement packets. I think the MAC address of the devices sending these packets are part of the packet payload (though I am not sure! Please clear that out). If yes, is there any way of reading that MAC address from the packet without connecting to the device? If no, then how to get such a MAC address? Perhaps, sending it using the manufacturer data field of the advertising packet?

Also, I think that the sd_ble_gap_addr_get() function returns the MAC address of the device on which the code is running. Am I right?

Thanks

Hi,

The address of the advertiser is sent along with the advertising packet. During scan you will get BLE_GAP_EVT_ADV_REPORT events, where you get the address of the peer in the peer_addr field of the ble_gap_adv_report_type_t in the ble event. (In the BLE event handler it would usually be p_ble_evt->evt.gap_evt.params.adv_report.peer_addr.) See sd_ble_gap_scan_start() and the ble_gap_evt_adv_report_t Struct Reference.

Yes, sd_ble_gap_addr_get() returns the identity address of the device running the code.
