EZ430 - RF2500 inconsistency !!

Hello

I am working with the EZ430RF2500 kit. I am trying to create a simple application for now that consists of sending some garbage data from one ED to the AP, and verifying that the data received is as expected.

I am basically using most of the code provided in the demo software. However, I am getting some inconsistent results when I download the firmware in.

There are times when I download the firmware, the application works great and the LEDs blink as expected. However, if I try to download the SAME code in again the next time round, it doesn't work, and both the ED and AP remain stuck in the process of setting up the network using SMPL_Link and SMPL_LinkListen respectively. But then, if I try to download the firmware in several more times, it sometimes work again on the 5th or 6th try.

So then my problem is that sometimes it works and sometimes it doesn't work, for the exact SAME code. Any idea why this might be happening? Thanks

    I have encountered this problem too! After spending literally hours hunting down bugs that I decided weren't there, I closed down the IDE (I use CCE) and unplugged the eZ430-RF2500. When I plugged the eZ430 back in and re-starting CCE, I proceeded to download the compiled code and, low and behold, it worked fine!

    I think there is a problem that occurs now and again with the eZ430's USB interface. It may even be only certain eZs, or certain eZs with certain PCs at certain times!, because lately I haven't had any problems and, since I now have five of the things, it may be that I've been using one that works all of the time, at least with my PC.

    So, my recommendation is that you close your IDE, unplug the eZ, plug it back in and start again. Of course, if this doesn't solve the problem it probably is your code. ;-)

    Note that once the eZ is working it usually keeps working until you unplug it from the USB port. Given that each eZ package comes with two RF target boards, the USB interface could be unlugged and plugged back into the PC several times a day, increasing the chance of this problem occuring.

    Hi.

    If you are using IAR you could try to do a 'clean' and 're-build all' upon downloading the code. For some reason it seems like IAR sometimes mix up the smpl_config.dat so that one end up running ED code instead of AP code and vica versa.
