Introduction

The NearLink driver module provides APIs for accessing and using the NearLink short-range communication protocol, including DLI initialization, data sending and receiving, and closing the NearLink DLI.

Constraints

The NearLink driver module is written in C++ and based on the DLI framework. It supports the standard system only.

Usage

NearLink DLI APIs are provided. The DLI APIs include initialization, sending and receiving DLI packets, and close.

DLI APIs

• Initialize the NearLink HAL:

/* Initialize the NearLink HAL and register the callback. */
int32_t SleHalInit(const sptr<ISleHciCallback>& callbackObj);

• Send a packet:

/* Send a packet to the chip. */
int32_t SleSendHciPacket(const std::vector<uint8_t>& data);

• Receive a packet:

/* Receive a packet from the chip. */
int32_t hciPacketReceived(uint32_t type, const std::vector<uint8_t> &data);

• Close the NearLink DLI:

/* Close the NearLink DLI and release resources. */
int32_t Close();
