Using eZ430-RF2500 target boards, I'm trying to make one a broadcast transmitter and the other a B/C receiver. Thus far, here are my attempts:
1 - I wrote code using the Temp Sensor code - which uses the SimpliciTI code as a library - as a starting point. After debugging, I discovered 2 problems. A) the transmitter would give a SUCCESS return code twice, then all subsequent R/C's were "NO MEM". I'm assuming I used up the two transmit buffers, indicating that nothing was ever sent. Any idea why? B) the receiver NEVER received anything. This may be because the transmitter never sent anything. All receiver statuses were NO_FRAME.
2 - I downloaded the SimpliciTI-IAR projects, thinking that the "cascading_end_devices" project may be a better starting point. When I tried to build it all, I got the dreaded IAR linker error that I was limited to 4k.
3 - I tried downloading and installing the complete CCE tools to get 16k. After much effort, I never could open up the project. The CCE tool apparently couldn't see the "project" file in the directory I provided it. Perhaps there's a limit to the number of characters in the file path? Also, the "problems" window indicated that directories couldn't be found at paths I never provided! (sigh)
4 - Miraculously, I stumbled across the "ks_version" command line option (I'm quite surprised this isn't more widely documented), and moved back to IAR. I managed to build the complete "cascading" project, and burned it into both target boards. Either will now go into "babble" mode (press/hold the button), but Neither will receive. Further debugging shows that ALL broadcast transmits return a SUCCESS code, but all receiver r/c's are NO_FRAME.
ANY IDEAS on how I might proceed?????
My target boards have SN's 23.30771 and 23.07397.
