Hi. Dear,
I tried to do wifi communication as follow site.
https://www.brainy-bits.com/how-to-use-the-nrf24l01-2-4ghz-wireless-module/#comment-151
I did it. But I have a problem. I used 3 types of modules. (Attached)
A - NRF24L01+PA+LNA with Antenna
B - Black one (No antenna)
C - Green one (No antenna)
When I use A as Tx and B as Rx, It is working. When I use all other combination(B as Tx and A as Rx,C-A, A-B,B-B,..), it did not work.
What is the wrong.
Please help.
Have a look at this Simple nRF24L01+ Tutorial.

Dear Robin2,
I tried it. But It were this messages.
SimpleTx Starting
Data Sent Message 0 Tx failed
Data Sent Message 0 Tx failed
Data Sent Message 0 Tx failed
Data Sent Message 0 Tx failed
...
And this on the receiver:
SimpleRx Starting
Data received Message 0
Data received Message 0
Data received Message 0
Data received Message 0
No errors other wise. Please help.

How frequent were the messages on the RX device? They should be about 1 per second. If they are coming much faster then it usually means incorrect wiring between the Arduino and its nRF24.
Have you tried the connection-test program which IIRC is in Reply #29?

Dear Robin2,
Yes,the messages came about 1 per second.
I didn't try the connection-test program.
I am a newer for this section. Can you help me to test connection.
I tried again as follow site.

I used Arduino Uno and NanoV3.
A - NRF24L01+PA+LNA with Antenna
B - Black one (No antenna)
C - Green one (No antenna)
When I use A with Nano, It is working(Transmitting and receiving). The Nano doesn't work with other modules. (This example didn't work anytime)
Thanks
