CCS/LAUNCHXL-CC2640R2: Pairing Error Code 8

Part Number: LAUNCHXL-CC2640R2

Tool/software: Code Composer Studio

Hi,

at the moment I am working with the CC2640R2 launchpad and I did all the trainings steps with the ProjectZero example. But when I do the pairing example, it won't work. I always get the message error "Paring failed, ErrorCode 8" at the terminal. I was following step by step of the tutorial. 

I did some further research and I found out, that I need several 1k of free RAM for the encryption during the paring. Checking the SRAM memory from a fresh "ProjectZero" application, I already use 16360 bytes from 17408 bytes.

Is there a way to reduce the RAM or  does something else cause this Error?

I hope you can help me!

Thank you

Christian
