SX1280,问下大家官方历程中BUFFER_SIZE和SendPayload的size有啥区别啊？

Xiuer666

packetParams.Params.LoRa.PayloadLength = BUFFER_SIZE;

void SX1280SetPayload( uint8_t *buffer, uint8_t size )
{
    SX1280HalWriteBuffer( 0x00, buffer, size );
}


void SX1280HalWriteBuffer( uint8_t offset, uint8_t *buffer, uint8_t size )
{
    uint16_t halSize = size + 2;
    halTxBuffer[0] = RADIO_WRITE_BUFFER;
    halTxBuffer[1] = ( offset ) >> 8;
    memcpy( halTxBuffer + 2, buffer, size );

    SX1280HalWaitOnBusy( );

    SpiIn( halTxBuffer, halSize );

    SX1280HalWaitOnBusy( );
}
