AT Driver for the RAK3172 WisDuo LPWAN Module
This respository contains a driver for the RAK3172 module running the RUI3 (RAK Unified Interface V3) firmware in AT mode. The driver is built on top of the atat crate.
The module doesn't really comply with the AT standard. In fact, the behavior of the module doesn't even match the official documentation. The following are the main differences we've found:
- There's no
\r\n
marking the beginning of a response - It uses test commands (
AT+FOO=?
) instead of read commands (AT+FOO?
) - Command parameters are separated by semicolons (
:
) instead of commas (,
)
To overcome the differences we had to build our own digester (i.e. the command parser in the atat world).
TODO
- Create a serializer similar to serde_at to support the limitations of the AT mode that we mentioned previously.
- Remove STD dependencies
- Publish on crates.io
