# LoRa Simple RX/TX Example

## Source Files

* `simple_rxtx.py` is a very simple implementation of a program to alternately
  receive and send LoRa packets.
* `simple_rxtx_async.py` is the same program implemented using async Python.

## Running the examples

One way to run this example interactively:

1. Install or "freeze in" the necessary lora modem driver package (`lora-sx127x`
   or `lora-sx126x`) and optionally the `lora-async` package if using the async
   examples (see main lora `README.md` in the above directory for details).
3. Edit the program you plan to run and fill in the `get_modem()` function with
   the correct modem type, pin assignments, etc. for your board (see top-level
   README).
4. Change to this directory in a terminal.
5. Run `mpremote run simple_rxtx.py` or `mpremote run
   simple_rxtx_async.py` as applicable.

Consult the [mpremote
documentation](https://docs.micropython.org/en/latest/reference/mpremote.html)
for an explanation of these commands and the options needed to run two copies of
`mpremote` on different serial ports at the same time.
