bluetooth-proxies VS esp-idf

If you're already using Home Assistant, you can install ESPHome on any ESP32-based device and use it as a Bluetooth Proxy hub. I already had some smartplugs and bulbs flashed with ESPHome, so it was as simple as adding a couple more lines of code to get a few BLE Proxy hubs, with no additional hardware required for the hub.

Home Assistant and Bluetooth Proxy is probably your best bet: https://esphome.github.io/bluetooth-proxies/

where can I find the yaml configuration file? I flashed the esp32 directly with the bluetooth proxy wizard, hence I never touched the yaml file myself. Is it stored somewhere in HA?

Yep, these are the way to go. Small and with a case, so ready to put around the house.

Using just your browser you can transform these into Bluetooth proxies for Home Assistant with https://esphome.github.io/bluetooth-proxies/

I think the sequence when using the web installer from here is that it first installed a basic EXPHome WiFi connector and once done, supposed to autmomagically install the BT Proxy software but it fails. It gives you the chance to rename it to something more appropriate but then you get some other 'web' ESP device pop up?

ESPHome uses a yaml file as input from which to generate the binary firmware file for your ESP. Flashing via their github as you did means it will use one of these predefined yaml files. Because you chose generic esp, it will be using this one. As you can see it already has the api: line in there (line 21).

with framework set to esp-idf (as per https://github.com/esphome/bluetooth-proxies/blob/main/gl-s10.yaml), the device logs stop at "Starting scheduler on APP CPU"

For returning to deep sleep from the wake-up stub you can take a look at how it is done in https://github.com/espressif/esp-idf/tree/master/examples/system/deep_sleep_wake_stub

I found the spi_lcd_touch example and flashed it, and it seems to run fine with either ili9341 or gc9a01 drivers selected (although both are mirrored, and one has the colours inverted compared to the other - both of which I assume are things I can fix in either driver).

If that's the case: You register a GPIO as event source and make a task waiting for it, that then just performs the I2C-transaction. Follow this example https://github.com/espressif/esp-idf/blob/master/examples/peripherals/gpio/generic_gpio/main/gpio_example_main.c

IDF contains stuff like https://github.com/espressif/esp-idf/blob/master/pytest.ini and https://github.com/espressif/esp-idf/blob/master/tools/ci/idf_pytest/constants.py which are not part of the pytest-embedded package.

ugh.. arduino.

Better to start with ESP-IDF, there's a pretty full featured well documented web server, and a lot more.

i've looked over the the ble peripheiral example https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/nimble/bleprph/README.md and i see it's using

Hi, I have device ESP32-S3-DevKitM-1 and i want to catch keystrokes from keyboard. I tried using this https://github.com/tanakamasayuki/EspUsbHost and example from espressif https://github.com/espressif/esp-idf/tree/release/v5.1/examples/peripherals/usb/host/hid/main but when i connect keyboard it is just connecting and disconnecting. Can anyone help me with this?
