Detailed Description

GATT Read parameters.

Field Documentation

union { ... } bt_gatt_read_params::@73

struct { ... } bt_gatt_read_params::by_uuid

end_handle

uint16_t bt_gatt_read_params::end_handle

Last requested handle number.

func

bt_gatt_read_func_t bt_gatt_read_params::func

Read attribute callback.

handle

uint16_t bt_gatt_read_params::handle

Attribute handle.

handle_count

size_t bt_gatt_read_params::handle_count

If equals to 1 single.handle and single.offset are used. If greater than 1 multiple.handles are used. If equals to 0 by_uuid is used for Read Using Characteristic UUID.

handles

uint16_t* bt_gatt_read_params::handles

Attribute handles to read with Read Multiple Characteristic Values.

struct { ... } bt_gatt_read_params::multiple

offset

uint16_t bt_gatt_read_params::offset

Attribute data offset.

struct { ... } bt_gatt_read_params::single

start_handle

uint16_t bt_gatt_read_params::start_handle

First requested handle number.

uuid

const struct bt_uuid* bt_gatt_read_params::uuid

2 or 16 octet UUID.

variable

bool bt_gatt_read_params::variable

If true use Read Multiple Variable Length Characteristic Values procedure. The values of the set of attributes may be of variable or unknown length. If false use Read Multiple Characteristic Values procedure. The values of the set of attributes must be of a known fixed length, with the exception of the last value that can have a variable length.
