# `Meshcore.Transport.Serial`
[🔗](https://github.com/nyannus/meshcore_ex/blob/v0.1.0/lib/meshcore/transport/serial.ex#L1)

Serial (USB/UART) transport built on [`circuits_uart`](https://hex.pm/packages/circuits_uart).

`circuits_uart` is an *optional* dependency – add it to your own `mix.exs`
to use serial connections:

    {:circuits_uart, "~> 1.5"}

Options: `:port` (required, e.g. `"/dev/ttyUSB0"`), `:baudrate` (default
`115200`), `:dtr` (default `true`), `:rts` (default `false`) and `:cx_delay`
(milliseconds to wait after opening, default `100`).

Some boards (e.g. Heltec V2) reset when DTR is asserted – if you get no
response try `dtr: false`. `Meshcore.create_serial/2` retries automatically
with the inverted DTR.

# `child_spec`

Returns a specification to start this module under a supervisor.

See `Supervisor`.
