Unexpected disconnect

[deamons]

Seems like ble-ansc is still the only possible way to get ANCS on raspberry. Got the script working and I can connect to the BLE device but after a few moments it just disconnects or with LightBlue I get an connection Alert Timeout interrogating the peripheral.
consol log:
Bleno: Handle: 68 UUID: 7069df31ed53 address 70:69:... on -> accept: Recieved a Pairing Request Hande:68 uuid: 7069df31ed53 Got a disconnect Got a disconnect Got a disconnect Got a disconnect Able: unknown peripheral 70:69:df:.. disconnected!
Is this a problem with iOS 9 or a configuration problem? Is this project still working?

Hello, I'm facing the same issues:

on -> stateChange: poweredOn
on -> advertisingStart: success
Bleno: Handle: 69 UUID: 4f1ea7 address 4f:1e:a7

Full debug log on Raspbian Jessie RPi1B with iPhone 6S iOS 9.3.1. I can't figure out whats going wrong.

Did you ever figure this out? I'm just starting out and having the same issue, iOS 12.3.1, node v8.16.1 (node 10.x was having issues with bluetooth-hci-socket), Raspbian 9 stretch on rpi3.
