Transceiver Issue or Not - Australia

#1 Post by aussieatlarge » 25 Aug 2017, 03:58

New to forum but not novice. I have purchased a Tranceiver from Jaycar ZW3102 - image attached. I have provided power to it and connected data pin to pin 19 (also tried 17) on Mega. On the upload tool I see the initialization then nothing else.
With the exact same setup - Tranceiver and Mega (pin2), I am able to receive data from the Arduino rc-switch library. I am testing with a Bauhn power-outlet transmitter.
On the RFlink Uploader I have both logging and application-logging running. When I push a button on the remote control I see no activity at all. Even if the device is not recognized, should I see something?
I realize that the crappy Jaycar receiver is NOT on the hardware list but I assumed that if rc-switch made sense of the signal then RFLink should show something??????
Any Aussies out there?

the data pin should go to pin D19 (aka RX1)
If you do not see any data, connect arduino pin 7 to ground and try again.
Also, make sure you use at least R46 of the firmware.

Pullup on 'RF data in' pin:
Connect Arduino PIN 7 to ground in order to disable an internal pullup on the RF data pin.
This is required for some RF receiver modules like the SRX882.

I've also got the same receiver from jaycar and can confirm grounding pin 7 gets it working. Thanks for the tip :D :D
