nrf52832 with SDK14 expected working?

tried same build just with NRF_SDK15=1 instead of NRF_SDK14=1 and I don't see that issue, webide connects fine from my android phone and process.env looks fine. The only issue is that I cannot connect to it from Chromium running on Raspberry Pi 4 both for SDK14 build an SDK15 build (maybe related to Bluetooth 5) while it works with SDK12 build. Console shows
