Hi, i'm working a BLE gateway with NRF52DK and S132 by using the demo example central uart.
The peripheral equipement advertise manufacturer data like this: 0x0001 during 5sec then 0x0002 during 5 sec and stop advertise.
But I want my gateway can only connect if the device advertise 0x0002 and not 0x0001.
So my question is how to get the manufacturer specific data in ble_app_uart_c ?
Thanks you for your answers !
Hi,
You can check if manufacturer specific data is present in the advertising report using the function adv_report_parse(BLE_GAP_AD_TYPE_MANUFACTURER_SPECIFIC_DATA,&adv_data, &dev_name), which is defined in the BLE Multi-link example. If found, the length and pointer to data will be stored in the argument dev_name.
Best regards,
Jørgen
Hi Jorgen,
I am using SDK 15.2.0, and I have the same query to display the manufacturer specific data.
I could not find the function adv_report_parse(BLE_GAP_AD_TYPE_MANUFACTURER_SPECIFIC_DATA,&adv_data, &dev_name in the Multi-link example.
Thanks

There was a new scanner module introduced in SDK 15.2.0, that use filters to only pass devices that fit the filter parameter to the handler. You will have to remove the scanner module and use the old method if you want to display any Manufacturer specific data. You might be better off with porting the example from SDK 15.0.0, where the module was not used.
Do you mean that there is not API that can parse a scan data in new SDK like SDK 15.3 for a manufacturer data ?
The filter feature only supports the following types:
/**@brief Types of filters.
*/
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;
This is for 15.3.0, but you might find it helpful:
