The
TwePacketAppUart class represents the extended format of App_UART received by the parent or repeater application App_Wings.
class TwePacketAppUART : public TwePacket, public DataAppUART
After executing parse<TwePacketUART>(), the packet information is stored in DataAppUART.
The simple format cannot be parsed.
parse<TwePacketUART>() will return E_PKT::PKT_ERROR. To inspect the contents, refer directly to the original byte sequence.DataAppUART Struct

};
payload represents the data portion, but the storage method varies depending on the macro definition.
If MWX_PARSER_PKT_APPUART_FIXED_BUF is set to 0 during compilation, payload will reference the byte sequence directly. If the original byte sequence is modified, the data in payload may become corrupted.
If MWX_PARSER_PKT_APPUART_FIXED_BUF is defined with a value greater than 0, a buffer of that size (in bytes) is allocated for payload. However, if the size of the serial data exceeds the buffer, parse<TwePacketAppUART>() will fail and return E_PKT::PKT_ERROR.
