How to use this library?

[MHamza81]

Hi,

I want to ask you how to use this library, I know this is a very stupid question but I am doing such kind of work for the very first time. I need to your help. I have 2 Raspberry Pi 3 model B, I want them to communicate with each other using NRF24L01 (not NRF24L01+). So far i have done the following things to make it work.

• Wired up the transceiver with both of the Raspberry PIs
• Installed node-nrf usinf "npm install nrf"

Now i need to know that how should I run the tests so that I can see if devices are communicating with each other. I get the following output when i run test.js on 1st device.

Output of first device:

PING out
Piping out 0
Piping out 1
Piping out 2
Piping out 3
Piping out 4
Piping out 5
Piping out 6
Piping out 7
Piping out 8
Piping out 9
Piping out 10
Piping out 11
Piping out 12
Piping out 13
Piping out 14
Piping out 15
Piping out 16

---

After this nothing happens. I keep the code running on other device at the same time.
Output of other device is something like

Output of second device:

Piping out 4091
Piping out 4092
Piping out 4093
Piping out 4094
Piping out 4095
Piping out 4096
Piping out 4097
Piping out 4098
Piping out 4099
Piping out 4100
Piping out 4101
Piping out 4102
Piping out 4103
Piping out 4104
Piping out 4105
Piping out 4106
Piping out 4107
Piping out 4108
Piping out 4109
Piping out 4110
Piping out 4111

---

It runs piping out for 4111 times.
The output of my test-details.js file of both the devices is as following:

Output of test-detail.js files of both devices:

I have no idea what am I doing wrong or how should i run the code on both devices or even if I am running the right scripts to test the libraries. I really need your help as i have no idea what I am doing and what i should be doing.

Thanks

@MHamza81, you'll need to change the value of the "role" variable in the program to anything but "ping" in the second device. By doing this, one device will send data while the other receives (or listens).
