I'm using 2 arduino unos, both of them are cheap clones but one of them uses smd atmega and other one doesn't...
I tried everything i could to make the smd one work with nrf24l01+ but it simply doesn't communicate 
I tried different power sources, soldered 10 microF capacitor but it didn't work...
I've completely checked my wiring multiple times but it denies to work
currently using the "checkconnection.ino" sketch to check for a valid connection
/*
If your serial output has these values same then Your nrf24l01 module is in working condition :
EN_AA = 0x3f
EN_RXADDR = 0x02
RF_CH = 0x4c
RF_SETUP = 0x03
CONFIG = 0x0f
This code is under public domain

#include <SPI.h>
#include <RF24.h>
#include <printf.h>
RF24 radio(7, 8);
byte addresses[][6] = {"1Node", "2Node"};
void setup() {
radio.begin();
radio.setPALevel(RF24_PA_MIN);
radio.openWritingPipe(addresses[0]);
radio.openReadingPipe(1, addresses[1]);
radio.startListening();
Serial.begin(9600);
printf_begin();
radio.printDetails();
}
void loop() {
// empty
}
the code i used
output on smd arduino (or arduino nano):
SPI Speedz = 10 Mhz
STATUS = 0x00 RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=0 TX_FULL=0
RX_ADDR_P0-1 = 0x0000000000 0x0000000000

TX_ADDR = 0x0000000000
RX_PW_P0-6 = 0x00 0x00 0x00 0x00 0x00 0x00
EN_AA = 0x00
EN_RXADDR = 0x00
RF_CH = 0x00
RF_SETUP = 0x00

DYNPD/FEATURE = 0x00 0x00
Data Rate = 1 MBPS
Model = nRF24L01+
CRC Length = Disabled
PA Power = PA_MIN
ARC = 0
I'm still kind of a noob so go easy :>
