Other Parts Discussed in Thread: MSP430F2274
I've created the design which you can find in the post 7522.design.zip . I've used TI's reference designs and design notes, the circuit is nearly the same with ez430-rf2500 kit except the balun circuit and antenna. I've tried using MSP430F2274, 2272 and 2252 as micro controller but couldn't succeed with the communication. I can send package to the kit's receiver but I can't receive any valid data. (sometimes some data comes but fails at crc check which I can see in debug mode) What can be wrong about the design?
Notes:
1- ez430-rf2500 kit's software is used for testing communication.
2- The ports are changed in the software for compliance with my hardware.
3- I've tested in different ranges: 1-5 meters
4- PCB is 35 micron FR4
5- The two circles in the bottom are for batteries.
