 The default build is based on the STM32F4Discovery board chip (`stm32f407vgt6`). If you want to target a different

For devices with either 512KB or 768KB of flash the available application flash space will be limited to 128KB. Devices with only 512KB of flash may also suffer from slightly reduced performance because the compiler must optimize for size rather than performance.

 ### Configuring the Console
 
-The default build for any `DEVICE` will use `USART2` and output will be on `PA2`. This default will work well for most `Discovery` and generic boards that do not have an on-board TTL to USB-COM support (including the `STM32F411CEU6` A.K.A. `BlackPill V2.0`). For `Nucleo` boards that do have on board UART to USB-COM support you may pass the `cmake` parameter `-DBOARD=nucleo` to have the correct USART and TX pins configured automatically. The `Nucleo-144` series use `USART3` and `PD8`, while the supported `Nucleo-64` boards use `USART2`, but passing the `BOARD` parameter along with `DEVICE` will configure the correct `USART` for your model. If any other boards are discovered to have on board USB UART support pull requests, or opening issues with the details, are more than welcome.

 In addition, the following optional parameters can be specified to configure the AP network (ESP32 only):
 
 * `{dhcp_hostname, string()|binary()}` The DHCP hostname as which the device should register (`<<"atomvm-<hexmac>">>`, where `<hexmac>` is the hexadecimal representation of the factory-assigned MAC address of the device).
+* `{beacon_timeout, fun(() -> term())}` A callback function which will be called when the device does not receive a beacon frame from the connected access point during the "inactive time" (6 second default, currently not configurable).
 
 The following example illustrates initialization of the WiFi network in STA mode.  The example program will configure the network to connect to a specified network.  Events that occur during the lifecycle of the network will trigger invocations of the specified callback functions.
