Please compare the prj.conf files of the heart rate Coded PHY sample and yours to make sure the Bluetooth configs match. Error -134 refers to "Not supported" so one or more of the parameters you've set is not supported by your project.

Hi,

thanks for the reply i gone through Heart rate example and try to set extended advertisement with coded phy i's giving error -134 ?

BT_LE_ADV_PARAM_INIT(BT_LE_ADV_OPT_EXT_ADV | BT_LE_ADV_OPT_CODED |

BT_LE_ADV_OPT_USE_NAME,

BT_GAP_ADV_FAST_INT_MIN_2,

BT_GAP_ADV_FAST_INT_MAX_2,

NULL);

this is my advertising parameter and

bt_le_ext_adv_set_data(adv, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd)); this function generating error. As I gone through some of the nordic support query regarding this issue i noticed that ad data and sd data can not be used concurrently so i tried with ad data only then the beacon device is not getting connected to central.

Please provide some suggestions

Okay

Can you provide some details on what devices exactly you're testing, what kind of environment you're testing in and show some logs of what you're doing and what happens when you go "out of range"?

A sniffer log using a Bluetooth Sniffer or the nRF Sniffer and Wireshark might be useful to see what's going on over the air exactly.

Thanks for the reply

I had gone through long range throughput example to know about how to set Coded phy and I am able set coded phy in my software still not getting long Range

Okay, how have you set up your advertising in your application then? Please refer to the Coded PHY sample in the SDK to see how to set up a device running in the Coded PHY: Bluetooth: Peripheral Heart Rate Monitor with Coded PHY

You should only need the following to set the application to use Coded PHY (125 kbps) in NCS:

CONFIG_BT_CTLR_ADV_EXT=y

CONFIG_BT_CTLR_PHY_CODED=y

You probably should not enable the CONFIG_BT_AUTO_PHY_UPDATE since this lets the application automatically update the PHY if you want to only stay at Coded PHY.

What application specifically are you using for testing here, so I can test on my end if you're still having issues on your end.

Best regards,

Simon
