5340 ble not connecting

[kamacode]

using any example with BLE I get the following:

when loading , prints on log : 

[00:00:00.291,595] <wrn> bt_hci_core: ECC HCI commands not available

and when I try to connect via NRFCONNECT (man phones used, multiple vendors) I get : 

Error 8, GAT connection timeour

additionally, device is not shown on scans ~ 1 minute from power up 

please advice how to resolve this issue , since this check : 

err = bt_enable(NULL)

pass OK , so it seens BLE is started OK

• What board version of the n5340 (P)DK do you have? Do you have a PDK or a DK?   - PDK
• What board name do you use for building the samples? If you use west could you provide the command, and if you use SES, could you provide the nRF Connect Options?  - , nrf5340pdk_nrd5340_cpuapp
• What NCS version are you using? SDK1.5.0

reading the commect below I do suspect it's an issue with 1.5.0 SDK since this worked with some olfer version (not sure what )

[kamacode]

after more testing, 1.4.9 works OK , there is an issue with BLE  on PDK + 1.5.0 

[kamacode]

so per "d_c_h_w" and mine findings, SDK1.5.0 BLE functionality is not working for the NRD5340, when can we expect SDK1.5.1?  (or a fix to this issue )

thank you
