@robotastic please make sure you are using the latest 0.4.3 release. This has been resolved by 4bcafd6. See discussion in noble/bleno#180.
Let me know if you think it is unrelated to the above.

I double checked and I am running v0.4.3. I erased the node_modules dir and reinstalled to be sure.
I think it maybe unrelated. I am able to do the initial pairing fine using the UART BTLE on the RPI 3. I get a stable connection for this initial connection that does not drop. I am doing this pairing from an iPhone and it is connecting using ANCS. After I confirm the pairing dialog on the iPhone, the RPI is listed under My Devices. If I go out of range or turn the bluetooth off and then on, on the iphone, there are the issues I listed above with reconnecting a paired link. It is really weird, since the link seems to be re-encrypting fine. After it disconnects, it will just start reconnecting again and endlessly loop like this.
Reconnecting a paired link works perfectly fine when I use a USB BT Dongle. Anything else I can try?
My code is up here: https://github.com/robotastic/ble-ancs
Here is a larger snippet of the HCIDump for more context, this is after the initial pairing and a disconnect:

This is happening because the kernel is going down a different path than the USB adapter:

because LE Read Remote Used Features is not supported in the adapter. You'll have to figure another workaround, to prevent the kernel from disconnecting things.

This should be fixed by c5d7f84, plus there is also #39 that has some re-working to try.
