Multilink central scan problem

[Akshat]

Hi,

I am using the nRF51-DK board as a central running with ble_app_multilink_central_s130_pca10028 sample application. I am using SDK version 9.0 with Keil 5.14 version. I have third party peripheral devices like Estimote, Sensor Tag. With the central device, I am not able to scan these peripheral devices. Can you please help me to scan these devices with the central board ?

Hi Akshat,

How did you test that ? Note that the multilink_central example only connect to and print out log when the device that has the short or complete name matches target.

What you should do is to print out the advertising data you receive when BLE_GAP_EVT_ADV_REPORT occurs.

Make sure you are scanning without any whitelist (selective scanning)

The current ble_db_discovery.c module doesn't support generic discovery of the att table. You would need to register which service you want to discover in advance. So the 128 bit UUID should be known. If you want to do generic discovery, you can base on what we do now, and implement the mechanism to follow every service to discover all the characteristic of each service.

Calling sd_ble_uuid_vs_add() should not return BLE_GATT_STATUS_ATTERR_ATTRIBUTE_NOT_FOUND please double check.
