Help with the sample code offered by sparkfun for nRF2401A!

I just bought one Transceiver Development Kit - nRF2401A (sku: WRL-00715). The link is here http://www.sparkfun.com/commerce/produc … cts_id=715

On the webpage, In “Example PIC code”, it offers two sample code:VO1 and V02, and it says the board is preloaded with V02. And I downloaded CC5X complier and WinPic, and then I complie the sample code V02 and use WinPic to rewrite it to one of the tranceiver board. However, it turns out to be the board doesn’t work anymore! So I read the hex file from the other tranceiver board and compared it’s content with the hex file that just has been genrated from V02 sample code, they are totally different! It starts to make me wonder the board is preloaded with other code instead of V02??!!

So is there anything wrong with the sample code??? Any help will be appreciated!!

Cheers,

I believe the pre-loaded code was compiled with the commercial compiler rather than the free one and as such is more optimised and doesn’t match that you compile with the free compiler.

Thank you so much! You are right!! Problem solved!!

What development platform did you use before loading the nrf2401a with WinPic? I have been trying to use MPLAB with CC5X and the transceivers do not appear to be talking with each other.
