Re: NRF24L01 RF Transceiver

I also have the + version. The only way I get 0x0000 is to disconnect any the power/miso/mosi/sck lines.
If I remove the spi module I get another error.
Can you confirm the module is working on your arduino?

Re: NRF24L01 RF Transceiver

Are you sure it's connected correctly? What model rpi you have?

Re: NRF24L01 RF Transceiver

when the addresses are in the same range I think it would be easy for 5 nodes. I haven't tried it yet because I have only an rpi and an arduino. My idea of the hub was to do something like the elektor bus protocol wireless. Simple star networks should not be too hard. for meshed networks a workaroun...

Re: NRF24L01 RF Transceiver

In my examples I used /dev/spidev0.0 and GPIO25
I have a model 1 rpi so you should check if the pins are on the same spot
nrf-vcc = rpi-3v3 (1)
nrf-gnd = rpi-gnd (6)
nrf-ce = rpi-ce0 (24)
nrf-csn = rpi-gpio25 (22)
nrf-sck = rpi-sckl (23)
nrf-mo = rpi-mosi (19)
nrf-mi = rpi-miso (21)

Re: NRF24L01 RF Transceiver

https://github.com/gnulnulf/RF24 contains the library.

Re: NRF24L01 RF Transceiver

I changed the RF24 library and SPI to have more flexability. // CE and CSN pins //RF24 radio(8, 25); //only CSN is NEEDED in RPI RF24 radio("/dev/spidev0.1",8000000 , 25); //spi device, spi speed and CSN,only CSN is NEEDED in RPI the status did not work until I changed: printf_P(PSTR("Data Rate\t = ...
