Detailed Description
GATT Attribute.

Field Documentation
uint16_t init_len |
Initial attribute value length in bytes.
Definition at line 130 of file ble_gatts.h.
uint16_t init_offs |
Initial attribute value offset in bytes.
If different from zero, the first init_offs bytes of the attribute value will be left uninitialized.
Definition at line 131 of file ble_gatts.h.
uint16_t max_len |
Maximum attribute value length in bytes, see Maximum attribute lengths for maximum values.
Definition at line 132 of file ble_gatts.h.
Pointer to the attribute metadata structure.
Definition at line 129 of file ble_gatts.h.
Pointer to the attribute UUID.
Definition at line 128 of file ble_gatts.h.
uint8_t* p_value |
Pointer to the attribute data.
Please note that if the BLE_GATTS_VLOC_USER value location is selected in the attribute metadata, this will have to point to a buffer that remains valid through the lifetime of the attribute. This excludes usage of automatic variables that may go out of scope or any other temporary location. The stack may access that memory directly without the application's knowledge.
