BBB & NRF24L01+

[flagadajones]

Hi Every body,

I'm newbie  on BBB  and i search  sample code & schematic  for use  NRF24L01+ with my BBB, i try many solution from RPi orums but it doesn't works.

thanks for your help.

What do you want to do?

What did you try?

What happened?

Hi,

I want to make communication between an arduino and a bbb.  Both have an nrf24l01+ module.

I have plug a nrf24  to  the spi0 on my beaglebone. 

and enabled SPI via  http://elinux.org/BeagleBone_Black_Enable_SPIDEV

I use then node-nrf module  and this script :

var NRF24 = require('nrf'),

    spiDev = "/dev/spidev1.0",

    cePin = 16, irqPin = 19;        

    pipes = [0xF0F0F0F0E1, 0xF0F0F0F0D2],

    role = 'ping';

var nrf = NRF24.connect(spiDev, cePin, irqPin);

//nrf._debug = true;

nrf.channel(0x4c).transmitPower('PA_MAX').dataRate('1Mbps').crcBytes(2).autoRetransmit({count:15, delay:4000}).begin(function () {

nrf.printDetails();

    if (role === 'ping') {

        console.log("PING out");

        var tx = nrf.openPipe('tx', pipes[0]),

            rx = nrf.openPipe('rx', pipes[1]);

        rx.pipe(tx);

    } else {

        console.log("PONG back");

        var rx = nrf.openPipe('rx', pipes[0]),

            tx = nrf.openPipe('tx', pipes[1]);

rx.pipe(tx);

    }

});

but nothing append on my BBB.

the call of nrf.printDetails()  print ll default values and not my configuration result.(.channel(0x4c).transmitPower('PA_MAX').dataRate('1Mbps').crcBytes(2));

cePin is plug on P9_15  and irqPin on P9_16

thanks for your help.

Hi,  

I've solve a part of my problems.  my cePin and irq Pin was incorrect.

Now NRF24 is recognize by bbb  but i haven't any communication between arduino and BBB.

My  BBB  printdetails: 

SPI device:      /dev/spidev2.0

CE GPIO:         51

IRQ GPIO:        48

STATUS:          0xe RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0

RX_ADDR_P0–1:    0xf0f0f0f0e1 0xf0f0f0f0d2

RX_ADDR_P2–5:    0xc3 0xc4 0xc5 0xc6

TX_ADDR:         0xf0f0f0f0e1

RX_PW_P0–5:      0x0 0x0 0x0 0x0 0x0 0x0

Data Rate:       1Mbps

Model:           nRF24L01+

CRC Length:      Disabled

PA Power:        PA_HIGH

My Arduino printDetails:

STATUS = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0

RX_ADDR_P0-1 = 0xf0f0f0f0d2 0xf0f0f0f0e1

RX_ADDR_P2-5 = 0xc3 0xc4 0xc5 0xc6

TX_ADDR = 0xf0f0f0f0d2

RX_PW_P0-6 = 0x04 0x04 0x00 0x00 0x00 0x00

EN_AA = 0x3f

EN_RXADDR 0x03

RF_CH = 0x4c

RF_SETUP = 0x07

CONFIG = 0x07

DYNPD/FEATURE = 0x00 0x00

Data Rate = 1MBPS

Model = nRF24L01+

CRC Length = Disabled

PA Power = PA_HIGH

can you help me to find where is the problem?
