hi guys
i have a nrf24l01 module and i am using it together with a pic18f45k20 and MickroC development tool.
here is the issue: i use flush RX command, the RX_EMPTY flag tells me it is empty, but the data that i read remains the first value that was first read.
for example, if i send 3,2,5,1,6 , i receive the same data, but after i flash RX, if i want to read again, it gives me 3 3 3 3 3.

Code: Select all

powerDown();
flushRX();

powerUP_RX();
//standby mode
enable();
//RX mode

delay_ms(2000); //wait for the transmition to take place (i send 9 integer numbers)

powerDown();

Chip_Select = 0 ;
SPI1_Write(0x61);          //R_RX_PAYLOAD  from RX FIFO
for(i=0;i<=8;i++)            // read the 9 integers sent
{
   read[i]= SPI1_Read(0xFF);  //send 0xFF dummy byte to generare de SPI CLK
  }
Chip_Select = 1 ; 

for(i=0;i<=8;i++){   //dispaly on the LCD.
GLCD_Fill(0x00);
IntToStr(read[i],value);
GLCD_Write_Text(value,40,4,1);
Delay_ms(50);}

if i transmit data, i get the good values. if i reset just the microcontroller and don't transmit anything, i get the first value that was send before reset in all the 9 values that i try to receive. If i reset the nrf24l01, RX_FIFO flushes and it's ok.

please help me

where you send flush rx command to the nrf?

I agree with JulsPower.

I don't see a flush rx command.

FLUSH_RX = 0xE2
