Literally, code that was working in the morning has not worked since the evening. That explains why, when Console starts, Trolley does not respond. Well, that command is supposed to block for ms, but not forever. Actual product may vary from the product photograph displayed above. I just noticed Programmer:

Fully satisfied with the product and 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.
This is usually related to power and bypassing which nRF24L01 modules are very sensitive to. I haven’t looked very carefully at your code but one thing I noticed is that it seems like you are unnecessarily using arrays for your commands.
Please submit the url of the better price you saw. He has taught electronics http: I had hundreds of nRF24L01 modules in kits I make for a large school system 2 years avrsip. I originally suspected hardware problems because I have had to transport the kit several times. Easy to Use, Versatile Robotics Kits Hi, nRF24L01 intermittent problems Work today, fail tomorrow are not uncommon.
Nothing I have thought of has got it working again: I was using Arduino 1. Let us know what you learn! I have always had problems with pointer addressing in the C-style languages so I retreated and went to Boards v.
Those little modules have a good 3. 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.
Found this item with same quality and at a lower price but prefer to buy from robokits. Do I need that when using a UNO? What is that, and is that the correct selection? This will tell you if your radios are working.
We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Free Economy Shipping option available Availability: I have just been browsing their websites and haven’t had any luck using the term Base Module.
Thanks a lot avriisp helping us to maintain competitive prices. Read 1 time previous topic – next topic. I described the problem in the original post. That explains why, when Console starts, Trolley does not respond.
Execution stalls at Trolley on a radio. I have just done a clean uninstall of that and replaced it with Arduino 1. I just noticed Programmer: It’s best to keep things as simple as possible to reduce the potential failure points but it’s also not a good idea to make unnecessary changes to your code until you’ve gotten it back to a working state, otherwise you can’t test the changes.
Last year all modules were supplied with the “Base Modules” shown on that page and the reliability was high. I began to suspect that some “upgrade” or other had corrupted the system on my PC so I changed jk11 Arduino 1.
What is “Programmer: AVRISP MkII”?
If you’re not using either of those then the Programmer setting makes no difference. 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 tried to concentrate on results instead of understanding – and it was working until I discovered that, as Terry put it, nRF24L01 intermittent problems Work today, fail tomorrow mk11 not uncommon. Avridp is only a programmer and no debugger. The only way I have a RF communication sketch is to modify the originals robin2 wrote – and at present they do not communicate.
