nrf51822 ble softdevice

[yanli_1226]

    I am using the nrf51822 ble with softdevice and want to know if the broadcast can start at a given time, and if the adv_ interval can change everytime? (such as I want to start broadcast after 12 hours, then broadcast 2 hours and stop 10 hours. and then broadcast 2 hours and stop 10 hours, and so on.)

Hi. 

Which version of the softdevice are you using with the nRF51822?

[yanli_1226]

I am using s130_nrf51_2.0.0_softdevice

Thanks.

There is no built-in way to set parameters like the one you are looking for.
See:
GAP Advertising interval max and min

You will have to implement a solution for this yourself, i.e using timers or on input action.
It's possible to change the advertising params each time you start advertising.
Note that the maximum timeout for advertising is 180s (GAP Advertising timeout values), so you need to advertise unlimited and control this with your application.

Best regards,
Joakim

thank you, then if other version of the softdevice have the parameters like this? (such as I want to start broadcast after 12 hours, then broadcast 2 hours and stop 10 hours. and then broadcast 2 hours and stop 10 hours, and so on.)

No, a specific requirement like that would have to be implemented by yourself.
