Part Number: CC430F5133

I am using CC430F5133 for an active RFID tag project. In this I am using Wake-on Radio mode to read and write the tag data like Tag ID, RF baud rate, Channel, transmit interval and transmit power. The tag will always be in WOR mode and at the same time it will transmit its ID in a specified time interval. I am using two different channels for WOR and Tag transmission. I am using WDT only to generate time interval. Everything gone well since I worked with 50 tags. Now I increased my tag count to 100, some tags are not working, i think the code is hanging.I couldnt find where the problem occuring. Expecting help from experienced engineers.

Your post has been moved to the MSP forum as they are the once supporting the CC430 from a SW point of view.

Have you referred to the CC430x513x WoR example from SLAA459? www.ti.com/.../slaa459a.pdf

You can use the debugger to test your theory that the code is hanging and locate the cause. I would expect a timing race condition to be involved if the latter half of the tags are always getting dropped. Make sure you are correctly stopping WoR mode by strobing SIDLE and STX when starting the transmitter, otherwise you may be encountering a timeout from the RX mode.
