Resolved: test 1 sketch on JeeNode v6, but no blinking LED
Hi - My first project with a JeeNode v6, but I’m having a little problem. Having assembled it, and successfully loading the test1 sketch, the LED doesn’t blink when it runs. The Arduino IDE reports no errors, and I have double checked my soldering on the JeeNode and the USB BUBII, but can’t find any problems. I’m also using the latest drivers and JeeLib library. I have place a couple of photographs and the sketch I’m using at the following links:
I also tried loading the RF12Demo sketch, and then opening Putty as a terminal emulator. When I do this, I get the following greeting:
[RF12demo.10] A i1 g212 @ 868 MHz
i - set node ID (standard node ids are 1..30)
b - set MHz band (4 = 433, 8 = 868, 9 = 915)
g - set network group (RFM12 only allows 212, 0 = any)
c - set collect mode (advanced, normally 0)
t - broadcast max-size test packet, request ack
…, a - send data packet to node , request ack
…, s - send data packet to node , no ack
l - turn activity LED on PB1 on or off
q - set quiet mode (1 = don’t report bad packets)
x - set reporting format (0 = decimal, 1 = hex)
123 z - total power down, needs a reset to start up again
Remote control commands:
,,, f - FS20 command (868 MHz)
,, k - KAKU command (433 MHz)
A i1 g212 @ 868 MHz

…so I think the RF module is still good? However, entering the command 1l and 0l on the keyboard appear to have no effect on the on-board LED.
Are there any other diagnostics I can use to test? My skills are very basic, and I don’t have much in the way of test equipment. I have a second JeeNode kit which I could assemble and test, but if I made a mistake in the assembly, I don’t want to replicate it on the second board. Many thanks in anticipation of any help.
With RF12Demo loaded try using the ‘t’ command and report back the messages you see. Also, try the ‘l’ and ‘1l’ commands, this should switch the led on and off. Do you have any other Jeenodes to test with?
Now I reread you have already done the ‘l’ tests.
* Update Did you fit the led with correctly, positive & negative legs?
Is this a trick question, I don’t see an LED in your photograph - does the V6 have an LED?
You got me, http://jeelabs.net/projects/hardware/wiki/JeeNode says no leds to save power when on batteries!
Hi - Thanks for the replies.
Re: “Update **** Did you fit the led with correctly, positive & negative legs?”
I haven’t actually fitted an LED (maybe that’s the problem?). I’m following the DIJN instructions, and on http://jeelabs.org/2013/02/04/dijn-03-store-code-in-a-jeenode/. Here it says “At this point, you should see a brief LED flash once a second. This indicates that the JeeNode is running the test sketch and sending out its counter packet once a second” My assumption was that the board has a surface mounted LED on it, as there is no mention of adding an LED to the kit in any of the instructions I’ve found. If this is the case, I feel incredibly stupid.
Aha, I see from the link in your last reply that the v6 definitely has no LED. The instructions are for an earlier version. I can take it from here. Many thanks for your help, I very much appreciate it.
