4.2 Set RF-NANO data transfer rate
RF-NANO data transmission rate has three levels, namely :1Mbps, 2Mbps, 250Kbps;Data transmission
rate can be set in the software. Open the rf-nano experimental routine program. In mirf. CPP, there is a
function to set the data transmission rate :SetSpeedDataRates(uint8_t val)
。
void Nrf24l :: SetSpeedDataRates ( uint8_t val ) //Select between the high speed data
rates:0=1Mbps, 1=2Mbps, 2=250Kbps
{
if ( val > 1 )
{
configRegister ( RF_SETUP , ( 1 << RF_DR_LOW ) );
}
else
{
configRegister ( RF_SETUP , ( val << RF_DR_HIGH ) );
}
}
