networking - NRF24L01 and arduino does not communicate correctly -

i trying exchange data between 2 atmega328p through nrf24l01.

1) library , sketch use tmh20 library here . , use getting started sketch start here .

i send first arduino witht code bool radionumber = 0; , second bool radionumber = 1;

but getting nothing ( 5 weird character on serial console).

2) schema , electronic

this image of schematic , picture of have on breadboard

also plug  ce -> d7 csn -> d8 sck -> d13 mosi ->d11 miso ->d12 

i add 10 micro farad capacitor between gnd , vcc of nrf24l01.

my voltage supply come power generator ( current consomption 0.6 2 arduino 2 nrf24l01 ). power supply provide 5 v , derive 3.3 v using lm3940 using first schema (simplied ) on datasheet here

3) symptom

nothing appear on serial console except 5 weird characters.i can't see light activity on nrf24 module.

if have idea debug thing ?

all best

if not see written setup part of code:

serial.begin(115200); serial.println(f("rf24/examples/gettingstarted")); serial.println(f("*** press 't' begin transmitting other node")); 

it related other things nrf communication itself. have remembered set baud rate in serial monitor 115200 baud? mismatch in baudrates common cause of weird characters shown in serial monitor.
