WL1837MOD: Bluetopia stack

Hi there,

We've been using Stonestreet one's Bluetopia stack for MSP430, Rev v1.5 R2, Bluetopia 4.0.1.10. This stack is compatible with the service pack (.bts) file V3.9 for our WL18xx device. 

I believe beyond that, TI has released its own Bluetopia stack and subsequent SP files have become incompatible with our stack. Is there any way to modify our stack to work with the latest Bluetooth script? Maybe some kind of BTS conversion tool that make it work on older stacks?

If not, where can I find resources for upgrading our Bluetopia stack?

Thanks,

Tian
