Hi,

You can change the address type in the st_target_periph_addr. See the example in ble_app_hrs_c.

hi Amanda ,

the good examples address is 7C:9E:BD:CC:08:02

and the cannot match example is 34:AB:95:49:4B:62

I cannot make sure all devices are using the same type. even I wanted to chang the scanning address type . I don't know how to change it , please suggest how to adding the address type in the filter by using the Software device API , thanks.

What is the mac address? You cannot set the address as .addr = {0}.

You should know what is the address type of the peripheral device using. Please check the advertising address and type with the sniffer.

Hi,

how to add the address type in the filter? since I tried to change the variable to BLE_GAP_ADDR_TYPE_PUBLIC ,but there is same result.

     ble_gap_addr_t st_target_periph_addr ={
            .addr_type = BLE_GAP_ADDR_TYPE_PUBLIC,
            .addr = {0}
        };

Hi,

[quote user="Kawing"]but another just report as UUID match only. Address filter show not match. [/quote]

What is the address type of those devices? Are they random static addresses? How do you check the advertising mac address? Are you able to check their mac addresses by sniffer? Is it the same as you set for the filter?

Hi Amanada,

Thanks for your reply.

I checked the address ordering are correct. Acturally , I have few same device, they have difference mac address only, half of them can report in all match case. but another just report as UUID match only. Address filter show not match.
