Chapter 4 Sets the transmitting power and data transmission rate
4.1 Set the transmitted power of RF-NANO
The transmitted power of RF-NANO has four levels: -18dBm, -12dBm, -6dBm and 0dBm.The greater the
transmitting power, the farther the transmission distance;The transmitted power can be set in the software.
Open the rf-nano experimental routine program. In mirf. CPP, there is a function to set the transmitted
power :SetOutputRF_PWR(uint8_t val), which can set different transmitted power
void Nrf24l :: SetOutputRF_PWR ( uint8_t val ) //Set tx power :
0=-18dBm,1=-12dBm,2=-6dBm,3=0dBm,
{
configRegister ( RF_SETUP , ( val << RF_PWR ) );
}
void Nrf24l :: config ()
// Sets the important registers in the MiRF module and powers the module
// in receiving mode
// NB: channel and payload must be set now.
