Other Parts Discussed in Thread: BLE-STACK, CC2650

Hello everyone

I want to use the cc26xx software crypto function for ecc and ecdh. Can anyone here give me some more instructions, examples or documentation about this software crypto functions?

Thank you

    Hi Jan,

    In any CC2650 SDK that predates BLE-Stack 2.2.1 you cannot use the ECC functions in the application. They are assumed to be owned by the stack and are not re-entrant.

    In BLE-Stack 2.2.1 and later you can use the ECC driver to call these functions in a thread safe manner. This driver is located in src\common\cc26xx\ecc. There are some comments in the header file that should facilitate use, there is no separate example of how to use.
