@brief Initiate or continue a GATT Characteristic Discovery procedure.

@details This function initiates or resumes a Characteristic discovery procedure. If the last Characteristic has not been reached, this must be called again with an updated handle range to continue the discovery.

@note If any of the discovered characteristics have 128-bit UUIDs which are not present in the table provided to ble_vs_uuids_assign, a UUID structure with type @ref BLE_UUID_TYPE_UNKNOWN will be received in the corresponding event.

@param[in] conn_handle The connection handle identifying the connection to perform this procedure on. @param[in] p_handle_range A pointer to the range of handles of the Service to perform this procedure on.
