Simple Bluetooth Client Examples

Is there any public examples of a stm32wb Bluetooth client application. Where the stm32wb client does a few read's and write to a server bluetooth applicaion. What i was thinking of was a BLE_HeartRate_Client program to the BLE_HeartRate program which is a bluetooth server. The two types of examples i see from the client's view are the ANCS which has to do with with apple Bluetooth notifications and the BLE_p2pClient application which is a semi involved example and its hard to figure exactly whats happening.
