I struggle to flash OTA over network (using bluetooth)

[tomatensaus]

Thank you for a brilliant project! I do not think people say this enought!

I am running a V11 of the JKBMS, flashing OTA over network only gets to 55% and then times out.
Running it 25 times maybe 1 will succeed.

The moment I disable the Bluetooth I can flash it over the network so I added the configuration below.
Maybe this can help someone? Maybe I can submit it as a PR to become part of the standard example?

Is this timeout a bug? Or just the way ESP32 bluetooth works? Bluetooth and Wifi compete for the same antenna.
Perhaps the WDT is timing out?

my workaround:

  - platform: ble_client
    ble_client_id: client0
    id: bluetooth_enabled_switch   # <--- add an ID so we can disable it from the OTA
    name: "${name} enable bluetooth connection"

and also

ota:
  on_begin:
    then:
      - lambda: |-
          id(bluetooth_enabled_switch).turn_off();
      - logger.log: "BLE shutdown for flashing"

If the ESP to too busy processing stuff OTA updates doesn't succeed unfortunately. IMO it's a general issue of the ESPHome core and cannot be resolved here but I like your workaround! Could you prepare a pull request?

I've the same issue on a ESP32 node while receiving serial traffic on three different UARTs. I've added the safe mode switch component here to reboot the node into safe mode before doing OTAs: https://esphome.io/components/switch/safe_mode.html

I would gladly prepare a PR to include the workaround in the standard examples
