This page is a work in progress as the API is changing as we migrate to S132v5 (nRF52832) and S140 (nRF52840) and add better Central mode support.
BLEDiscovery is a helper class to make finding characteristics on a Gatt server (hosted on a BLE peripheral) easier. For service discovery, the BLEClientService's discover() API must be used, as shown below:
BLEDiscovery(void); // Constructor void begin(void); bool begun(void); void setHandleRange(ble_gattc_handle_range_t handle_range); ble_gattc_handle_range_t getHandleRange(void); uint8_t discoverCharacteristic(uint16_t conn_handle, BLEClientCharacteristic* chr[], uint8_t count); uint8_t discoverCharacteristic(uint16_t conn_handle, BLEClientCharacteristic& chr1); uint8_t discoverCharacteristic(uint16_t conn_handle, BLEClientCharacteristic& chr1, BLEClientCharacteristic& chr2); uint8_t discoverCharacteristic(uint16_t conn_handle, BLEClientCharacteristic& chr1, BLEClientCharacteristic& chr2, BLEClientCharacteristic& chr3); uint8_t discoverCharacteristic(uint16_t conn_handle, BLEClientCharacteristic& chr1, BLEClientCharacteristic& chr2, BLEClientCharacteristic& chr3, BLEClientCharacteristic& chr4); uint8_t discoverCharacteristic(uint16_t conn_handle, BLEClientCharacteristic& chr1, BLEClientCharacteristic& chr2, BLEClientCharacteristic& chr3, BLEClientCharacteristic& chr4, BLEClientCharacteristic& chr5);
For concrete examples of how to use this API see the 'Central' folder in the examples that are part of the BSP.
