Abstract: This application discloses a Bluetooth connection method, and relates to the field of short-range wireless communications technologies. The method includes: A terminal sends a service inquiry request to a Bluetooth device after the terminal and the Bluetooth device establish an asynchronous connectionless ACL link. The service inquiry request includes information about a service supported by the terminal. The Bluetooth device sends a service inquiry response to the terminal in response to the service inquiry request. The service inquiry response includes information about a service supported by the Bluetooth device. The terminal performs pairing with the Bluetooth device after the terminal receives the service inquiry response sent by the Bluetooth device. The terminal establishes a connection based on a first service to the Bluetooth device when both the terminal and the Bluetooth device support the first service. This reduces a period of time for establishing a Bluetooth service connection.

Abstract: An Internet of Things data transmission method includes sending, by a terminal device, a first data request to a server, and continuously receiving, by the terminal device, N data packets from the server. The first data request instructs the server to continuously send a plurality of data packets. The first data request includes a quantity N of data packets, that the terminal device is capable of continuously receiving, and a time interval for sending two consecutive data packets, where N is an integer greater than 1. The N data packets include at least one non-confirmable Constrained Application Protocol (NON) data packet, a sending time interval between two consecutive data packets in the N data packets and the at least one NON data packet indicates that sending a receiving response from the terminal device to the server is unnecessary.
