I'm trying from weeks to get the SRX882 receiver working with RaspberryPI with no chance.

I've bought SRX882 in addition to STX882 but cannot find a way to get them working. I've tried using RFSwitch with no success..no signal received from the receiver. Could someone help me getting it work? Connection schema of receiver is: VCC->+3.3V, GND-> GND, DATA -> PIN2(WiringPI), CS (disconnected)

On some Arduino's site I read that "Connect Arduino PIN 7 to ground in order to disable an internal pullup on the RF data pin." but I was not able to activate it on RPI,cannot receive any data at all

    you cannot receive data if you are not transmitting data

  • I am trasmitting...the STX882 or my car Controller is on the same Freq..no result on RFSniffer

  • no result on RFSniffer .... does not mean there is no RF being detected? ...... please provide a detailed connection diagram ...... what is the purpose of CS and why did you decide to leave it disconnected?

  • According to nicerf.com/Upload/ueditor/files/2016-08-29/… CS should be set to logic 1 for normal operation. So I guess you need to strap it high.

    Can you see any data with piscope?

"CS (disconnected)" generally stands for "chip select". Its purpose is to allow having more than one device on common path, thus "connecting " to selected device on the bus. It is commonly connected to output pin and activated by grounding it. Check you receiver datasheet to make sure about the activation level.
