Disconnecting instantly after sucessful connection

[Toshimonster]

Currently running dietpi.

Everything works, except when I try to connect; It works for ~3s and disconnects.
Btmon shows this as a Remote User Terminated Connection

Any idea how I can find out what is giving this disconnect request?

Logs are running the echo example.

Any help would be greatly appreciated, been at a loss for a very long time now, and it seems google does not contain any solutions.

I tested on RPI CM4 and RPI 3 B+.
Nodejs v14.18.1 and Nodejs v17.0.1

what?
Why would BLE use regression and bissectors, unless your talking about something else?

well yes, but this isn't a versioning issue

(earlier version doesn't work)

Would appreciate any help, as although I know about bluez, the custom implementation is all brand new to me and I'm struggling to realise where this starts.
Otherwise I'm going to have to implement another form of GATT server, eg via python, but IMHO that gets rid of the point of writing in node in the first place!

While I prefer the interface in this library, if anyone else is having a similar issue another similar library exists at
https://github.com/Emill/node-ble-host
which does not have this issue.

Yes, I tested several Raspberry Pi OS (from 2018 to latest release), all have the same issue. Although bleno works fine on PC with USB BLE dongle. I guess it's not Raspberry Pi OS issue. It's a bug on node-bluetooth-hci-socket v0.5.3-8. (https://github.com/abandonware/node-bluetooth-hci-socket/pull/32]

I rollback to v0.5.3-7, everything works fine for me.

npm install bleno@npm:@abandonware/bleno
npm install @abandonware/[email protected]

Thanks @xuminready - this fix also worked for me when using FortiusANT on RPi0. Greatly appreciated!
