Advertising doesn't start immediately after calling sd_ble_gap_adv_start

[Fabian Hauschild]

Hi everybody,

I'm having a problem with the advertising function of the SoftDevice.

When the application starts advertising the function "sd_ble_gap_adv_start()" returns without an error.

But it takes up to 10 seconds until I can see the advertising with the nRF Connect App.

How can I fix this?

I'm using

Laird BL654 (nRF 52840)

SDK16

SD140v7.0.1

Best regards Fabian

Hi,

What advertisement interval are you using? Could you check with a sniffer when the first advertisement package is sent on air?

Note that in case the advertiser and scanner interval uses similar intervals, it could take some time until the scanner captures the advertisement packet.

Hi,

I'm using a 500ms advertising interval. 

I don't have access to a BLE Sniffer (I could try using nRF Sniffer with a nRF52840 DK. But itwill take some time setting this up)

We have been testing our BLE products with nrfConnect for Android and PC.
