Peripheral not connecting to iOS

Question

I'm attempting to connect a bluez peripheral to an iOS device; it's not working.

Please find below logs on peripheral side. I'm advertising using hciconfig hci0 leadv but I don't see any "Connect" option on Scanner applications on phone. Also bluez-4.101 doesn't have hciconfig hci0 leadv0 option to make it connectable.

With the same device acting as a Central I am able to make LE connections with other BLE devices, so that confirms kernel LE support and device is fine, only some bluez issues I assume are there.

How can I get this peripheral to connect?

Upgrading to the latest BlueZ version will solve the GATT related issues.

The 2.x , 3.x and 4.x series of libraries and packages are deprecated and not supported anymore by BlueZ developers. If you are using them please update to the 5.x series. The download link is only provided for reference.
