Hello list,
I just got my pi433 working somehow on Raspberry Pi Model B Rev 2.
Here are my findings:
first I need to enabling spi in config.txt on boot partition.
dtparam=spi=on
then adding this node to bcm2835-rpi-b-rev2.dts and compile.
&spi0_gpio7 {
pi433: pi433@0 {
compatible = "Smarthome-Wolf,pi433";
reg = <0>; /* CE 0 */
#address-cells = <1>;
#size-cells = <0>;
spi-max-frequency = <10000000>;
pinctrl-0 = <&pi433_pins>;
DIO0-gpio = <&gpio 24 0>;
DIO1-gpio = <&gpio 25 0>;
DIO2-gpio = <&gpio 7 0>;
status = "okay";
};
};
Then loading spi_bcm2835 and pi433 modules:
modprobe spi_bcm2835
modprobe pi433
Is this the right usage to send some data over the air?

Best regards,

Hi Oliver,
thanks for testing with real hardware :-)
In my product, I use Raspbian. Therefore, I work with a kernel from
Raspbian. Raspbian supports device tree overlays.
So I don't use dtparam=spi=on, but dtoverlay=pi433.
I don't modify the bcm2835-rpi-b-rev2.dts, but use the
pi433-overlay.dts, provided in the driver documentation.
I am not sure, whether you need to load spi_bcm2835. I never did that,
but maybe it is done implicitly on my system.
Never adressed Pi433 from command line, but always used a program to do so.
Anyway: The way you did it, you missed to setup the tx and/or rx
configuration. I am not sure, whether there are useful defaults in the
current version of the driver, allowing you can start with tx right from
the start. Most probably all entries are preset with zero, that might
lead to an not really perfect configuration of the chip. So you need to
use the ioctl first, to set usefull config params.
I don't know, what generates the hundrets of "write: generated new msg
with 2 bytes.".
This message is shown up, as soon as you ask the driver to send
something. There is an internal (SW) queue, where tx jobs get stored.
The message tells you, that a telegram with 2 bytes was stored in this
queue. I guess the two bytes are the '1' and a new line, generated by
the echo. The repetition of the message is quite strange.
Maybe due to misssing configuration / bad default settings.
As soon, as there is something in the queue, the driver should leave RX
mode (where he was waiting for messages in the air) and start to
transfer the messages from the queue with the given (or in your case
missing) configuration for TX. As soon as the queue is empty, the driver
should reconfigure for RX and restart listening on the air.
Unfortunally I can't find the source code from my testprogram, that is
compatible with the current version of the driver. Hope I didn't format
the wrong SD-card.
Just found sources for the "old" version of the driver, that was
intended to support more then just Pi433...
Will provide the source as soon as I find it.
At the moment, I just can provide a binary, if it helps...
Hope this helps understanding,
regards,
Marcus
