### Initialize the function
bool init(uint8_t NSSPin = NSS_PIN, uint8_t NRESETPin = RESET_PIN);
### Initialise rx mode
bool rxInit();
### Sending packet through RF
bool sendPackage(uint8_t* sendbuf,uint8_t sendLen); // length of data to send,less than 64 bytes
### Receive packet from RF
uint8_t receivePackage(uint8_t* recvbuf);
### Inquire interrupt
bool waitIrq(uint8_t irqMask = LR_RXDONE_MASK); // LR_RXDONE_MASK and LR_TXDONE_MASK
### Clear interrupt
void clearIRQFlags();
### Enter low power consumption
void sleep();
### Enter standby mode
void idle();
### Read rssi
uint8_t readRSSI(uint8_t mode = 0);
