Double SPI Radio Raspberry Pi

[TriXwooD]

I have connected as an experiment two nrf24l01+ to the raspberry pi (spi enabled), my goal is to change one of the nrf24l01 for a lora or a 433... but since I do not have either yet, two nrf24l01+ it is :-)

I decided to try spi0.1 (with the cs on pin 26) because of the bluetooth/spi1 stuff...

The first radio is wired like on the homepage

The second radio has its MOSI,MISO, SCLK, GND, 3.3v connected on the same wires as the first radio

And the additional wires to
IRQ=pin 16
CE=pin 18
CS=pin 26

And 47pF cap between ground and vcc on the radio's (4.7pF does not work even if I wire one radio)

So I have two MySensor folders configures with

./configure --my-transport=nrf24 --my-rf24-ce-pin=18 --my-rf24-cs-pin=26 --my-rf24-irq-pin=16 --spi-spidev-device=/dev/spidev0.1 --spi-driver=SPIDEV --my-port=5004 --my-node-id=15

./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --spi-spidev-device=/dev/spidev0.0 --spi-driver=SPIDEV

Anyway although the both run and something got transmitted and received... its kinda not working... individually (one 3.3v disconnected or both connected) they work fine communicating with my vento sensor... so the radio's are fine. (and so are the use of the alternative pins)

but when both powered, the original pin radio works but the second radio does not (even with 3.3v/ground on other pins) or visa versa...

when both using mysensors it crashes

Was kinda hoping somebody could shed a light on why...
is it the cs line not being low from the other radio? signal too weak?
interference with packages? ?

also tested dtoverlay=spi0-cs,cs0_pin=24,cs1_pin=26 and dtoverlay=spi0-hw-cs in the /boot/config.txt to no avail,

also note with one radio I did not activate the dtparam=spi=on, it still worked...

2x nrf24l01 is one mysensors gateway and one milight, although I have milight in rflink :-)

@TriXwooD Update:

Two radio's (or alternative pins for one radio :-))
for the nrf24l01

For Raspberry Pi with 40 pins header (pi zero, pi 3,..)

Note on post above: I tried spi1.0 instead of spi0.0 and spi0.1 and it works... (cs lines not interfering?)
Still not sure why did spi0.0 and spi0.1 not work... what did I wrong there? It should be possible to share the mosi/miso/sclk/gnd/3.3v pins... (maybe it is the cs? or ce?... anyway)

This probably means rfm69 wired correctly and a nrf24l01 will work both at the same time on a pi ;-)

Can I compile one gateway with both rfm69 and rf24 enabled at the same time, thus not running two gateways?

For now two gateways running on a pi zero (pi3 with bluetooth not yet tested)

Step Zero
Enable spi1 in /boot/config.txt

sudo nano /boot/config.txt

dtparam=spi=on
dtoverlay=spi1-1cs,cs0_pin=36

First Radio Pin
Same as Building a Raspberry Pi Gateway page (with irq pin 15!)

First Radio Configure
With irq pin 15!

cd MySensors

Configuring...

./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --spi-spidev-device=/dev/spidev0.0 --spi-driver=SPIDEV --my-port=5003
make

Running...

cd bin 
sudo ./mysgw -d

Second Radio Pin

pin 01 3.3v
pin 33 for irq
pin 35 miso
pin 36 cs
pin 37 ce
pin 38 mosi
pin 39 gnd
pin 40 sclk

Second Radio Configure
(in another terminal)

A copy of the source

cp -r MySensors MySensorsSecond
cd MySensorsSecond

Configuring...
Note the port is 5004 instead of 5003, you can not run two gateways on the same port

./configure --my-transport=nrf24 --my-rf24-irq-pin=33 --my-rf24-ce-pin=37 --my-rf24-cs-pin=36 --spi-spidev-device=/dev/spidev1.0 --spi-driver=SPIDEV --my-port=5004
make

Running...

cd bin 
sudo ./mysgw -d

it works... Fin!

currently running openmilight on radio 1 and mysensors on radio 2 ;-)

@TriXwooD nice work, thanks for sharing!

About your question; MySensors only supports one transport per instance so you need to compile two gateways.

[seal]

@TriXwooD : i can confirm - i succesfully run two radios - rfm69 and nrf24 on RPi - on the spi0 runs rfm69 and on spi1 runs nrf24. Started two separated mysensors gateway on ports 5003 and 5004 and everythng runs fine! :)

I finally got RFM69 and NRF24 working on the same RPI3 with dietpi running :grin:

[gohan]

@llegoff @TriXwooD I think it would also worth mentioning that also the install scripts in "MySensorsSecond/initscripts" folder need to be modified if you want the service to get properly registered with the new name

@TriXwooD said in Double SPI Radio Raspberry Pi:

dtparam=spi=on
dtoverlay=spi1-1cs,cs0_pin=36

@TriXwooD : Thank you, this helped me a lot. I had to use a different pin number in /boot/cmdline.txt though for that it matches the pin number given in the configure statement:

dtparam=spi=on
dtoverlay=spi1-1cs,cs0_pin=16

./configure --my-rf24-cs-pin=36 ...

Configure wants the BCM pin number (36), but the dtoverlay wants the corresponding GPIO pin number (16).
