Trying to get RioRand 433MHz RF Link receiver to work on Pi3

Sat Aug 03, 2019 8:04 pm

hello,
I have purchased a RioRand(TM) 433MHz Superheterodyne RF Link transmitter and receiver kits 3400 for ARM / MCU from
https://www.amazon.com/gp/product/B00HE ... UTF8&psc=1

The first thing i am trying to do is get the receiver to work

I have not been able to find an exact howto but found a bunch of related sites.

so what i have done ::
i went here https://www.princetronics.com/how-to-re ... -receiver/
installed wiringPi and 433Utils

i am using 3.3v to power the receiver from an article i found
https://forum.pimatic.org/topic/202/4-h ... ven-more/2 . where there is a section Homeduino on Raspberry Pi where it mentions
Here’s one big difference to the Arduino wiring : the receiver will be connected to 3.3V!!
It is very important, since the Raspberry Pi can only handle 3.3V on the GPIO pins.
The Raspberry has a 5V out but when you connect the receiver’s VCC to 5V, the level of the data pin will be 5V too an this kills the GPIO of the Pi!
with all that i run
~/433Utils/RPi_utils/RFSniffer

i point an RF device at it and nothing

so now i am at a loss.

would love any help or suggestions

not used that h/w but have used similar with an arduino..

looking at the amazon page it looks like the receiver expects 5v to drive it. so i would get hold of a 3.3v/5v logic level shifter, to accommodate 3.3v to 5v 2 way data coms and protect your pi gpio from the 5v signals and run the device off 5v.. https://www.amazon.com/Cylewet-3-3V-5V- ... way&sr=8-1

the tx device can use 3-12v and will probably transmit a stronger signal with the higher voltage..

thank you,
will give it a try, just ordered the 3.3v/5v logic level shifter

thanks

i got the 3.3v/5v logic level shifter

Hooked it up following this diagram ( currently only hooking up the receiver )

Still nothing.

I should mention, i am a software guy not a hardware guy.. Is there anyway to debug this?

Thanks for any Help

how are you attempting to detect the signals your expecting to capture?

when using similar h/w with an arduino to hijack some fine offset protocol signals containing temperature and relay status metrics from a hacked stc1000 i used the libs developed by luc small to do the bit banging..

Not sure about your amazon receiver, but I use Joan's
https://www.raspberrypi.org/forums/view ... p?t=124663
and it works perfectly with the older type 433mhz receivers and transmitters.

Very simple to setup up reading with putty and python for sending
Might be of some help to you
