BBB with nRF24L01+: Cannot send/receive data

[Hồng Quân Nguyễn]

Hi guys,

I have difficulty controlling nRF24L01+ on BeagleBone Black using Python.

I use this library https://github.com/jpbarraca/pynrf24
Here is my code: http://pastie.org/10836500

Here is output of printDetails:

STATUS          = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1    = 0xe7e7e7e7e7 0xc2c2c2c2c2
RX_ADDR_P2-5    = 0xc3 0xc4 0xc5 0xc6
TX_ADDR         = 0xe7e7e7e7e7
RX_PW_P0-6      = 0x08 0x08 0x00 0x00 0x00 0x00
EN_AA           = 0x3f
EN_RXADDR       = 0x02
RF_CH           = 0x60
RF_SETUP        = 0x06
SETUP_AW        = 0x03
OBSERVE_TX      = 0x00
CONFIG          = 0x0c
FIFO_STATUS     = 0x11
DYNPD           = 0x00
FEATURE         = 0x00
Data Rate       = 1MBPS
Model           = nRF24l01+
CRC Length      = 16 bits
PA Power        = PA_MAX

For the other side, we use Arduino.

The problem is that:

- BeagleBone side cannot send to Arduino side, with error MAX_RT

- BeagleBone side can receive data from Arduino side, but now cannot receive.

Do you have any notice for me to make it work?

I connect nRF24L01+ to SPI0 port of BeagleBone, so it should not have conflict with HDMI.

I get this error, any idea? thanks.

root@beaglebone:~# python send.py

Traceback (most recent call last):

  File "send.py", line 9, in <module>

    from nrf24 import NRF24

ImportError: No module named nrf24

[Graham]

It means that python is looking for a code module named nrf24.py, and it can not find it.

So, either you don't have it, or you put it in the wrong place.

Have you installed the relevant library? (I think it may be:
