Read value by UUID

[peit]

Hi

If data is read by handle, it reads all the 20 bytes I need:

struct bt_gatt_read_params read_params;


read_params.func = read_func;
read_params.handle_count = 1;
read_params.single.handle = 14;
read_params.single.offset = 0;

bt_gatt_read(conn, &read_params);

but if it's read by UUID, it only reads 19 bytes..

struct bt_gatt_read_params read_params;


read_params.by_uuid.uuid = &uuid_128.uuid;
read_params.by_uuid.start_handle = 0x0001;
read_params.by_uuid.end_handle = 0xFFFF;
read_params.func = read_func;
read_params.handle_count = 0;

bt_gatt_read(conn, &read_params);

Why ?)

I needed to call the bt_gatt_exchange_mtu() function, now everything works.
