Bluetopia stack on Tiva c TM4C123HJ6PM

Other Parts Discussed in Thread: CC2564, CC256XEM-RD


I'm trying to use the bluetopia stack in tiva c launchpad (TM4C123HJ6PM microcontroller)

with  the CC2564 Bluetooth controller using the CC256x Bluetooth® evaluation module reference design

but I'm getting always this error with the examples, I tried with SSPDEmo and HIDDemo

I'm getting this error message in serial terminal:

Stack Initialization Failed: -4.
Unable to open the stack.

I added the CC2564 patch as is indicated here

and also I did a lots of checks in my hardware connection.

the Tiva C Board is sending the first packet but the bluetooth module doesn´t answer

I'm stuck

Could someone suggest me how proceed?
