Found this comment in a homeassistant thread.. this worked for me! first pair with old libs and one paired flash with new!
so this is not a soulution but a work-around

but is it a esphome bug or a bug in this lib @simonszu ?
Depends on how you look at it I guess. In the 1.x series of this custom component, the custom component managed the bluetooth connection on it's own using the arduino library. Looking at the source for that, it they have implemented support for SMP (Security Manager Protocol). In the 2.x+ versions, all the manual bluetooth connection stuff was dropped in favor of the ble_client implementation in esphome. BUT the esphome implementation doesn't yet support SMP, so in the 2.x+ series, you probably cannot actually fully pair the device. So esphome basically initiates a connection, but doesn't fully establish the connection, so then it disconnects after about 30s when the desk drops out of pairing mode.
I'm in the process of trying to implement some of the SMP stuff so that this should work...though i'm not normally a C++ developer, so there's a bit of learning curve. I can verify that during the connection process, we (esphome) are receiving a ESP_GAP_BLE_SEC_REQ_EVT event, that the current esphome implementation does nothing with. This event is basically the desk telling the esphome that it wants security stuff set up.
So I guess, technically it's a bug that this custom component swapped the bluetooth implementation pre-maturely, given that esphome doesn't support the pairing stuff the desk is attempting to do. But the fix is ultimately that esphome needs to be updated to support the security protocol.

Hello,
I tried to replicate your problem and got the same thing, the latest ESPhome version.

Same problem here.
EDIT: I had originally tried with the newest version of ESPHome (2022.1.1).
When that failed, I tried with version 2021.10.0 since that's specifically mentioned for this project - but got the exact same result.
My desk was a recent purchase (January 2022). I don't know if it's possible that the Linak firmware is of a newer make that's somehow incompatible?

Maybe i found a solution for updating position while moving... but it's arduino code and no ESPHome... how can i convert the code?

Did at least someone open a bug in esphome since they need to fix that apparently?
