pub struct ble_gatt_chr_def { pub uuid: *const ble_uuid_t, pub access_cb: ble_gatt_access_fn, pub arg: *mut c_void, pub descriptors: *mut ble_gatt_dsc_def, pub flags: ble_gatt_chr_flags, pub min_key_size: u8, pub val_handle: *mut u16, pub cpfd: *mut ble_gatt_cpfd, }

Fields§

§uuid: *const ble_uuid_t

Pointer to characteristic UUID; use BLE_UUIDxx_DECLARE macros to declare proper UUID; NULL if there are no more characteristics in the service.

§access_cb: ble_gatt_access_fn

Callback that gets executed when this characteristic is read or written.

§arg: *mut c_void

Optional argument for callback.

§descriptors: *mut ble_gatt_dsc_def

Array of this characteristic’s descriptors. NULL if no descriptors. Do not include CCCD; it gets added automatically if this characteristic’s notify or indicate flag is set.

§flags: ble_gatt_chr_flags

Specifies the set of permitted operations for this characteristic.

§min_key_size: u8

Specifies minimum required key size to access this characteristic.

§val_handle: *mut u16

At registration time, this is filled in with the characteristic’s value attribute handle.

§cpfd: *mut ble_gatt_cpfd
