How to use Bluetooth with ESP32 & NodeMCU in Lua

How can I use the bthci Bluetooth module in Lua language?

I used the NodeMCU Builder to make my firmware(dev-esp32), but there is no checkbox for the Bluetooth. Is it possible to use Bluetooth?

For now (i.e. until BT support is available for the cloud build) you need to build the firmware yourself if you need BT support. I suggest you start with the Docker image specifically built for that as per our documentation at https://nodemcu.readthedocs.io/en/dev-esp32/build/#docker-image.

The actual challenge is to know what BT options you need to turn on in the ESP-IDF - those are specific for your use case. https://github.com/espressif/esp-idf/tree/master/examples/bluetooth contains a number of examples and each one has a list of required flags in its sdkconfig.defaults file e.g. https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/hci/controller_hci_uart/sdkconfig.defaults

Is it possible to use Bluetooth?

Yes, it is. The configuration is more complicated than with other modules as it is so versatile.
