How to make advertising timeout variable

[Frank. H]

I want nrf51822 to switch between 2 different advertising timeout. One will set advertising timeout with 20s, another will keep advertising.

Currently, I use following code to set advertising timeout. It can't be changed.

"#define APP_ADV_TIMEOUT_IN_SECONDS 20 "

And I try to change APP_ADV_TIMEOUT_IN_SECONDS with a variable parameter. Like:

"uint32_t APP_ADV_TIMEOUT_IN_SECONDS=20"

But it fails. (Didn't run to main() )

Please help me to solve this problem or any other idea? Thank you.

Be more specific about "but it fails". What are the changes to some baseline example project (and which you use)? What error code and where you get? Or how do you detect the failure?

[Frank. H]

The compiler process is OK. Get in debug mode. The failure is that the process didn't run main() after modify APP_ADV_TIMEOUT_IN_SECONDS to uint32_t.

That sounds strange, I would bet it either won't compile/link/load to the chip or it runs at least through start-up code up to your initial calls in main().

Does it work if you change it back to #define APP_ADV_TIMEOUT_IN_SECONDS 20 ?

[Frank. H]

Yes，if I change the definition back, it works normally. And I just want to know that it is possible to make APP_ADV_TIMEOUT_IN_SECONDS to be a variable parameter. I have try many method but fail.
