How to read manufacturer specific data

[Maxim]

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

Yes it works, i have add in the central example in the function is_uuid_present this code:

while...

else if (field_type == BLE_GAP_AD_TYPE_MANUFACTURER_SPECIFIC_DATA)
        {
		         SEGGER_RTT_printf(0,"type: 0xFF\n");
                 SEGGER_RTT_printf(0,"data: %02x:%02x\r\n", p_adv_report->data[index+2],p_adv_report->data[index+3]);
        }

Thanks a lot !

Hi Maxim/Jorgen

I have the same query as yours but could not locate the is_uuid_present function in the whole code ( central/ multilink ) example.

Thanks
