Limitations on adv_slow_timeout

[Ingfu]

Hi,

I'm trying to use the ble_adv_slow feature of NRF52 with SDK 13.1.0. Unfortunately it behaves very strangely: it works with a timeout of 100(s) (ble_adv_slow_timeout=100) but fails with a NRF_ERROR_INVALID_PARAM when using a timeout of 200.

Are there any limitations on the slow timeout that i am not aware of?

Hi. 

Maybe you could add some more information about your application and how you have configured your advertising?

If you look at the documentation: 
GAP Advertising timeout values

The Maximum advertising time in limited discoverable mode is 180 s.

Best regards, 
Joakim

Thanks, that is the issue. Is the maximum value defined by the BLE specifications?
