Dear nordic

I changed my BLE application to coded phy for long range (chip used nrf52840) . application works fine(debug). 

But i cant see any advertising  in smart phone BLE appliation's 

I need a help to see my device advertising packet . I think device advertising has no problem but its not seen in smart phones  

can you help me to find out why smart phone not detect the advertisings.

is it any other way to find device properly advertise or not?

need some helps

What smart phones?

And running what operating system(s)?

And what version(s) ?

Do the phones and/or operating systems support BT 5 features?

Note that many BT 5 features are optional (as mentioned in the link) - are you sure that the Coded PHY is supported ... ?

Hi Alan,

That the phone supports BT5 does not mean it supports DLE or coded phy, since these features are optional, so you don't need to have them to support BT5.

You can check which features are supported if you take a sniffer trace and see the feature exchange between phone and nRF52840. You can use nRF sniffer for example.

But be aware that we haven't seen any phone that supports coded PHY in the market yet.

If you want to experiment with all the features for Bluetooth 5 I recommend you purchasing two nRF52840 Preview Development Kits.

See this blog post about how you can test the long range (with LE Coded PHY) feature with 2 nRF52840 DK here https://devzone.nordicsemi.com/b/blog/posts/testing-long-range-coded-phy-with-nordic-solution-it-simply-works-922075585
