Update: the long range example worked (max range 300 meters). Thank you for your help awneil and Simonr

same result, seems to cause a runtime error. I will try to convert the long range example linked by awneil.

Sorry, I see I wrote NONSCANNABLE... This should of course be scannable. Try again!

Best regards,

Simon

Time to get debugging, then ...

Or just start with Nordic's test code:

with these parameters the advertising led of peripheral does not turn on and central does not pair with peripheral

Hi Mort

First of all, you have to use extended advertising for coded PHY to work. I see in your advertising parameters on the peripheral side that you're not doing that. Please set adv_params.primary_phy = BLE_GAP_PHY_CODED; and
adv_params.properties.type = BLE_GAP_ADV_TYPE_EXTENDED_CONNECTABLE_SCANNABLE_UNDIRECTED;

The 52 Dongle antennas are not optimized for long-range use, so you will likely not be able to achieve as good results as in the long-range test linked by awneil, but you should see a significant increase in range anyway. The long-range test is also a very good reference when implementing coded PHY to your project.

Best regards,

Simon

Can you replicate their results using the same code & methods?
