Can't get JeeNode to configure via serial monitor. Help a noob.

Added by grajmahal about 6 years ago

Hi all. I have a couple of jeenode v6s that I am trying to get to pass an “open” or “close” signal with. I have uploaded theRF12 Demo sketch, but all I get back on the serial monitor is “[RF12demo.9] A i1 g212 @ 433 MHz” - they don’t respond to any input attempting to, for instance, change the frequency to 915MHZ, and I don’t see all the lines of settings that I understand I should be seeing. I can get them to do simple Arduino tricks like flash an LED, so I know that they are functional. What am I doing wrong here?

Thanks

Additional information - I am using a USB BUB II, and the sketch seems to work properly when run on an UNO. I tried flashing the ATMEGA in a UNO and then physically swapping it into the JeeNode, and I get the same problem. Is this an issue with the USB BUB?

Thanks (again, in advance) for your patience with a know-nothing. John

Are you using the latest jeelib?
Has RF12demo ever worked on these devices?

Current jeeLiib, yes. I have now found that if I upload the sketch to a regular UNO and change the settings (frequency, etc) via serial monitor on the UNO, I can swap the chip back to the JeeNode and the full functionality will be there. So I guess that problem is avoided for the time being.

Now, with the coding. I just want to send one of two commands between nodes ( “go” and “stop”, for instance). There don’t seem to be any ultra-basic tutorials on how to make these guys talk to each other using the Jeelib library. I can handle the arduono stuff, but the JeeNode specific code eludes me. Does anyone have a resource?

Thanks again

John
