Hi Ivan, Nice to hear news from you!
So, you don't to flash NuttX inside Anna-B112, but just want to use it as external BT BLE module, right? In this case you need to enable the "Bluetooth H4 UART" There are some examples on NuttX about how to use it. Also you can opt for using NuttX internal BLE Stack (that derives from an old BLE Stack that Intel integrated on Zephyr and that was released for Arduino/Genuino under BSD License) or you can use the NimBLE stack that is more complete and also have examples on NuttX. Using the internal stack could be more challenging, but it will help to improve our own stack.
