unable to connect nrf52832 dk as central to peripheral device(sensortile)

[Waqar Ahmed]

i am trying to connect nordic nrf52832 dk as a central to my custom peripheral(sensor tile) .peripheral is advertising different services and uuid of the one of service is (00000000-000f-11e1=9ab4-002a5d5c51b).i have run uart_central example from sdk 15 on nrf52832 dk.as nordic scan for its own vendor specfic uuuid.i have also changed the nordic base uuid with peripheral uuid(00000000-000f-11e1=9ab4-002a5d5c51b).still i am unable to connect.i

Hi,

It may have something do to with endianness of the UUID, maybe you can set a breakpoint in adv_uuid_compare() in nrf_ble_scan.c to find the cause. This function is called in nrf_ble_scan_on_adv_report() when there is an BLE_GAP_EVT_ADV_REPORT event from the softdevice. The actual UUID to filter for is set in scan_init() in the ble_app_uart_c example project.

Best regards,
Kenneth

thanks for answer.peripheral(sensortile bluetooth 4.0) advertisement packet does not contain any uuid .it only contain manufacturer specific data and power level.although i successfully make a connection between nrf52832 dk and sensortile by altering code ble_uart_c but nrf5832 doesnot discover any service.what will be the reason
