Hi Hung Bui, Can we use nRFgo Studio to do development work or compile code on the nRF24LU1+ device? Is it a free software or require a license.?

Yes; the Product Page (linked earlier) clearly tells you that the MCU interface is SPI:

Thanks for the answers. carsonmorrow.com/nrf24lu1p.php The above link has some useful information of using SDCC for nRF24LU1+. I will check on that. As I see, nRF24L01+ responds to the commands from the MCU via SPI.

@awneil: We use KEIL C51 for that.

What compiler do you use for your 8051 examples?

@awneil: I am aware of SDCC but I haven't seen it worked with the nRF24LE/U or at least we haven't tested here, maybe someone else successfully managed to do I'm not sure.

SDCC supports 8051 and runs on Linux: sdcc.sourceforge.net/index.php

He said that the nRF24LU1+ is in an "RFID Tag" ...

Hi Pradeep,

Yes, they can talk to each other. All our nRF24L, nRF5x chip can talk to each other as they work in the same ISM band 2.4GHz.

The nRF24L01P is pretty easy to use, you can simply base on the datasheet to know how to use Shockburst protocol.

For the nRF24LU1+, we provide the nRFGo SDK with example for Enhanced Shockburst protocol. It should work out of the box.

I assume you will connect the nRF24LU1+ to a PC or something via USB when operating.

I'm not aware of something ready on Linux that you can use to compile code for the nRF24Lx.

As already explained in the other answers, they are radio transceivers - it is up to the system designer to choose & implement whatever protocol they wish to achieve their design goals.

If you're not designing the system, then you will have to ask the designer about their design!

I am reading about Enhanced Shock burst protocol in the data sheet pointed by nRF24L01+. I am not designing the system. I have to understand the protocol between the two chips. Are the two chips designed for communication with each other? Is it possible to have the library of the communication protocol and test code.?

Yes, there is an answer to the one pointed by you. But I was referring to the one pointed by RK.

RE: RFID application.(Reader and Tag)

awneil — Tue, 22 Dec 2015 08:24:23 GMT

Yes, there is an answer (and a comment to back it up) - look again: devzone.nordicsemi.com/.../

Your question doesn't seem to make sense:

Are you trying to design this system?

Or is this an existing system that you're working on?

Or what?

Have you studied the documentation for the nRF chips?

RE: RFID application.(Reader and Tag)

Pradeep Chl — Tue, 22 Dec 2015 07:38:45 GMT

there is no answer to the question that is mentioned by you, please try to answer by question which is specific to my application.

RE: RFID application.(Reader and Tag)

RK — Tue, 22 Dec 2015 07:07:46 GMT

Or this one .. devzone.nordicsemi.com/.../

RE: RFID application.(Reader and Tag)

Pradeep Chl — Tue, 22 Dec 2015 03:54:52 GMT

Okey, I have edited my question. The two chips I meant was nRF chips.

awneil — Mon, 21 Dec 2015 16:11:16 GMT

Are you duplicating this question: devzone.nordicsemi.com/.../ ?

RE: RFID application.(Reader and Tag)

awneil — Mon, 21 Dec 2015 16:09:09 GMT

You have mentioned three chips - so which "two chips" are you asking about?

Linux is hardly "bare metal"
