WARNING Can't connect to ESPHome API for screek-ble-monitor-1a.local: Error resolving IP address:

Hi, I've been trying to set up an ESP32 classic with your code, so that I can void using directly connected USB Bluetooth dongles. I have a Home Assistant instance, and the ESP32 yaml below - but am getting the API error shown at the bottom of this post....are you able to offer any suggestions as to what I am doing wrong?

Ah - the issue seems to have been resolved by adding a specific IP address to the wifi YAML section

Now it's works? The component can't be source of this problem, you can try to remove only ble_gateway part and see how this works without component.

Yes, the problem was that mDNS was not working on my network.

By specifying the io address in the esp32 yaml, this problem was avoided
