Summary --------------------------------------------------------------------------------------------------------- Created a minimal demo application for Bluetooth. It works by displaying some data over Bluetooth and the user can connect to the device running it on NuttX and read this data. This can work in 2 scenarios: a real scenario, in which data from the BME680 (temperature, humidity, etc..) is used and the user will be able to read it. The second scenario involves displaying some dummy data (hardcoded values) for testing purposes. This application can serve as an example for users implementing more complex applications using Bluetooth on NuttX. Testing --------------------------------------------------------------------------------------------------------- I used the ESP32-Sparrow (which includes the BME680 sensor) and the ESP32-devkitc boards for testing. The Bluetooth stack starts by default with advertising when it initializes, however I noticed that enabling advertising in the stack does not work (at least on ESP32). However, when scanning is also enabled, the device starts advertising. Therefore, in our application, during the BLE services initialization part, I also enable scanning as a temporary workaround in order to make sure the device advertises and the user can see it and connect to it.
