Battery Service Configuration, BLE PTS requirements

Question

Have configured battery service as the example ble_app_hrs. 
 This works well, but the BLE PTS fails. 
 The battery service has been configured for multiple instances.
It is mandatory to support presentation format descriptor if supporting Multiple Instances. 
 How to disable battery service multiple instances configuration?
Or how to provide the presentation format descriptor? and What should this presentation format descriptor be set too?

Hi Tim, 
 according to the Battery Service Specification v.1.0, section 3.1.2.1,
when a device has more than one instance of the Battery service, each Battery Level characteristic shall include a Characteristic Presentation Format descriptor.
This is an optional feature. 
 The Battery Service module supplied with the nRF51 SDK v.7.1.0 does not include a Characteristic Presentation Format descriptor.
Therefore, it does not support multiple instances. 
 The PICS (Profile/Protocol Implementation Conformance Statements) selection in PTS should reflect the capabilities of the implementation. 
 Please see the attached screenshot for PICS that apply to the Battery Service module supplied with the nRF51 SDK v.7.1.0. 
 
 For further details please refer to the Battery Service Test Specification v.1.0.1.
