Changing Scan window in run time

[Sameer]

Hello Everyone,

I am building an application where I have to change the scan window (BEARER_SCAN_WINDOW_DEFAULT_MS) in run time, based on a specific event. Does the stack allow application to change it in run time??

Regards,

Sameer

Hi, 

Please clarify, you are using our Mesh SDK ? I'm not sure why you want to change BEARER_SCAN_WINDOW_DEFAULT_MS  ? In Mesh usually the scan window should be 100% unless you want to modify the scanning time. 

If you want you can change that, but you need to disable scanning and then init it again.

Hi Hung,

Yes, I am using Mesh SDK and I want the scanning to be off for sometime. Hence, I am trying to modify BEARER_SCAN_WINDOW_DEFAULT_MS.

If you want to put the chip to low power mode, I think the better solution is to stop mesh and put the chip to sleep for a period instead.

Reducing the scan window causes the mesh performance to drop drastically. 

But if you want to test that, I don't see any problem. Just need to stop and start scanning (scan_disable() , scan_init() )
