Zephyr and SDK5 coded phy compability

[qwertynoon]

I warry wander this fact.

I have migrated my project from SDK5 to ZEPHYR (nrf connect). Two devices - Central and Peripheral - Long range coded_phy.

I used next samples <peripheral_hr_coded> & <central_hr_coded> for coded_phy implementation and <shell_bt_nus> & <central_uart> for NUS implementation.

So, when I include coded_phy part of samples to NUS samples - Peripheral and Central did not see each other, but SDK5 version of Peripheral connected to Zephyr Central

And Zephyr Peripheral connect to SDK5 Central.

So I dont understand, why Zephyr Perihperal dont connect (even dont see) to Zephyr Central???

I have changed everything.... Zero effect

Help me please! I dont have a time((((

I think the reason is here

BT_LE_ADV_PARAM_INIT(
                     BT_LE_ADV_OPT_CONNECTABLE |
                     BT_LE_ADV_OPT_SCANNABLE |
				     BT_LE_ADV_OPT_EXT_ADV |
				     BT_LE_ADV_OPT_CODED,
				     100,
				     100,
				     NULL);

When I put BT_LE_ADV_OPT_CONNECTABLE and BT_LE_ADV_OPT_SCANNABLE  together then I get an error

[1;33m<wrn> bt_hci_core: opcode 0x2036 status 0x12

Without BT_LE_ADV_OPT_CONNECTABLE  Central receive advertising but with error

I see you have 

CONFIG_BT_LL_SW_SPLIT=y

on the peripheral, do you see any changes if you set 

CONFIG_BT_LL_SW_SPLIT=n

?

Thanks for reply

CONFIG_BT_LL_SW_SPLIT=n cause BT_CTLR_ADVANCED_FEATURES = n and nothing changed else

If I change BT_LE_ADV_OPT_CONNECTABLE to BT_LE_ADV_OPT_SCANNABLE then Central scan Peripheral but with wrong address and not connected

[00:06:42.515,106] <inf> central_uart: Filters matched. 10:c7:d3:7d:47:ec
[00:06:42.516,815] <inf> central_uart: Connection pending

[00:06:45.516,784] <inf> central_uart: Failed to connect to 10:C7:D3:7D:47:EC (random) (2)
[00:06:45.622,497] <inf> central_uart: Filters matched. 10:c7:d3:7d:47:ec
[00:06:45.624,206] <inf> central_uart: Connection pending

10:C7:D3:7D:47:EC - this is wrong address of Peripheral
