Communicating with non-qbcan devices

[krokosik]

I've been trying to send data from an RPi with RFM69HW attached (433MHz), but no matter what I try it seems that the two devices don't see each other. Are qbcans only able to communicate with other qbcans?

I'm not familiar with the qbcan RF side myself (@danisors or Han will be here soon to answer your question specifically), but regarding use of the RFM69HW - you'll need to ensure you're using the same modulation (or a compatible modulation), baud rates, sync words, framing, etc. Until Dani/Han reply, see if you can receive on the RPi, from the qbcan. This should allow you to check that you have compatible configurations on both sides.

I have already tried that. Also, I've been using the LowPower Lab's library ported to Python by entrombly, so I believe it is essentially the same library that is used by the qbcan.

Ok.

@danisors : ?

Ensure you're using the same encryption key also - The qbcan should be capable of talking to other devices which use compatible coding schemes, although I haven't validated that explicitly.

[krokosik]

Yes, the keys are the same.

Are you trying to communicate from a RPi with a RFM69 to a qbcan? If that is the case you should be able to communicate if both RFM69 have the right parameters set:
//Radio Parameters
#define NODEID 2 //unique for each node on same network
#define NETWORKID 100 //the same on all nodes that talk to each other
#define GATEWAYID 1 //Receiving node
#define ENCRYPTKEY "sampleEncryptKey" //The same on all nodes!

That's what I did, it looks a little bit different on RPi, since it's in Python, but I checked it multiple times and it should work.
