ESP_GATTC_REG_FOR_NOTIFY_EVT not being recieved after ESP_GATTC_WRITE_CHAR_EVT

The problem

I am running an ESPHome BLE proxy communicating with a BLE device.

The client device expects a ESP_GATTC_WRITE_CHAR_EVT and then the client device triggers a ESP_GATTC_REG_FOR_NOTIFY_EVT to the server.

This works with the ESPHome for about 30 minutes, then I get a BT_APPL: gattc_conn_cb: if=3 st=0 id=3 rsn=0x13

Which version of ESPHome has the issue?

2024.2.1

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2024.2.5

What platform are you using?

ESP32-IDF

Board

Olimex ESP32-POE-ISO

Component causing the issue

bluetooth_proxy
