RE: How to enable Coded PHY (Long Range) advertising on nRF54L15-DK using nRF Connect SDK 3.0.2?

Btw if you also want to just test the 8dbm long range coded phy, you can use radio_test example in the sdk, it uses uart to change the output power.

Hi mertpalaoglu1,

[quote user=""]What is the minimal correct setup to advertise over Coded PHY on the nRF54L15-DK? [/quote][quote user=""]Is there a sample or working snippet specifically for Coded PHY extended advertising I can reference?[/quote][quote user=""]Is there any sample that I can use to test the bluetooth long range, 8db tx power for 1 central and 1 peripheral nrf54l15 devices.[/quote]

Please refer to the Bluetooth: Peripheral Heart Rate Monitor with Coded PHY.

These Kconfigs in particular enable advertising over Coded PHY: https://github.com/nrfconnect/sdk-nrf/blob/v3.0.2/samples/bluetooth/peripheral_hr_coded/prj.conf#L16-L17

Source code showing how to start advertising can be found in main.c.

To fix TX power to 8dB, set CONFIG_BT_CTLR_TX_PWR_ANTENNA to 8.

[quote user=""]How can I make the signal appear continuously on a spectrum analyzer (without long silent gaps)?[/quote]

How long a silent gap are we talking about here?

If you use the nRF Connect app on your phone, what does it say the advertising interval is?

You seem to expect to find all the advertising packets in channel 37. That is not the case. Please refer to the answer here: Extended Advertising on Coded PHY Questions .
