The ble advertising for more than time specified in firmware

[mridula]

Hi,
 I am using the Nordic NRF52832 with SDK 16.

My device is configured to advertise continuously for a specific duration.

However, when tested using the nRF Connect app, it appears that the device is advertising for longer than the duration set in the firmware.

I am attaching the screenshot of the issue:

From the screenshot we can see that the device is advertising for around 45 seconds but in our firmware we have set the advertising duration for the device as only 30 seconds by setting the following parameter as given below :

p_advertising->adv_params.duration = 30*100;

We have tested this in different devices and have got similar results.

Might this be an issue with the firmware ? or is there anything more we need to configure to achieve the correct advertising duration ?

Regards,

Mridula

Hi Mridula, 
We have a similar ticket here: Fast Advertising Timeout Units

Can you take a look ? Our test here with the default example it seemed to work exactly as it should.
