Protocol

The device can be controlled via a UART connection (RX/TX and also RTS#/CTS# for flow control).

The default baud rate is 115200, but the chip can be reconfigured to other baud rates, too.

The protocol is mostly ASCII-based, using a specific AT command set, publically documented by the vendor.

Commands and responses always end with \r\n.
