How to add manufacturer specific data filter inside the nrf_ble_scan module ?

[Vashi]

Hi,

I want to add manufacturer specific data filter in nrf_ble_scan module.

I have gone through the nRF SDK. But  the manufacturer specific data filter related fields are missing.

Kindly guide me how to configure the filter for manufacturer specific data in nrf_ble_scan module.

 

Regards,

Vashi

Hi Vashi

Please check out this case where an example on how to add a manufacturer specific scan filter with the nrf_ble_scan_filter_set() function. See the Multirole LESC example for more details.

Best regards,

Hi Simonr,

I have gone through the code which you shared. I found that following filters are available in the file nrf_ble_scan.h

Here the Manufacture specific data filter is missing.

typedef enum
{
SCAN_NAME_FILTER, /**< Filter for names. */
SCAN_SHORT_NAME_FILTER, /**< Filter for short names. */
SCAN_ADDR_FILTER, /**< Filter for addresses. */
SCAN_UUID_FILTER, /**< Filter for UUIDs. */
SCAN_APPEARANCE_FILTER, /**< Filter for appearances. */
} nrf_ble_scan_filter_type_t;

Below function is used to set filter type:

ret_code_t nrf_ble_scan_filter_set(nrf_ble_scan_t * const p_scan_ctx,
nrf_ble_scan_filter_type_t type,
void const * p_data)

Suppose if i want to enable "Manufacture specific data filter"

Related flag is not defined in the enum ------> "nrf_ble_scan_filter_type_t"

Please guide me how to enable this flag ???

Hi Vashi

As mentioned in the case I linked to, you will have to use the SCAN_UUID_FILTER to scan for manufacturer specific data, as the manufacturer data also has a specific UUID you can use to scan for. You will need to know this UUID though, and put both the UUID and the manufacturer specific data into your advertising packet.
