I originally suspected hardware problems because I have had to transport the kit several times. Read 1 time previous topic – next topic. Offhand, do you have any suggestion as to how proven code could just stop working? I’m saying you need the RF24 equivalent of Blink, so simple that you know there’s no chance of a bug in the sketch. Lithium-Ion Rechargeable Cell 3. I am having problems getting existing, proven, code to run. I have just been browsing their websites and haven’t had any luck using the term Base Module.

What is “Programmer: AVRISP MkII”?

Hi pert Firstly, I am not ignoring your suggestion to Those little modules have a good 3. I began to suspect that some “upgrade” or other had corrupted the system on my PC so I changed from Arduino 1. The nRF24L01 modules were designed to plug into a arvisp board with good low-inductance bypassing and solid 3. I just noticed Programmer: These show in the attached version.

This is usually related to power and bypassing which nRF24L01 modules are very sensitive to. Literally, code that was working in the morning has not worked since the evening. What is that, and is that the correct selection?


Programmer is working excellent. Execution stalls at Trolley on a radio. It is compatible with Atmel Studio 6. That explains why, when Console starts, Trolley does not respond. I had noticed that, when starting, Trolley stalled somewhere in loopso I started adding debug messages until I found the location of the stall.

I took the hardware to school for a demonstration and when I got it home that unchanged code avtisp not work. Many students had intermittent problems. A couple of hours working though this again and again getting things right until I am sure the setup is as it should be. Hi, nRF24L01 intermittent problems Work today, fail tomorrow are not uncommon.

Found this item with same quality and at a lower price but prefer to buy from robokits. Whatever is going on with these versions of AVR Boards is beyond me, but again I retreated and re-installed v.

I cannot figure out why what worked in mk11 morning has not worked since. If you have them enabled the Arduino IDE will pop up an updatable boards notification when there is a new version available of any of your installed hardware cores. avrsp


Full Name Email Address. I described the problem in the original post. Please submit mmk11 url of the better price mi11 saw. On Wednesday morning I had working code. Nothing I have thought of has got it working again: Uploading this version of Trolley without Console even being powered up results in the output: I’ll get on to that a.


I have set these lines in setup in both instances of the sketch Code: Fully satisfied with the product zvrisp the delivery system of Robokits india I have booked this Programmer and selected one day delivery option and it reached in one day i am happy with commitment that robo india makes and stick with the commitment nice job by robokits india keep working like this.

The only way I have a RF communication sketch is to modify the originals robin2 wrote – and at present they do not communicate. Actual product may vary from the product photograph displayed above. I suspect the problem is not software at all.
