This Arduino library provides a buffered serial interface via telnet.
SerialViaTelnet is derived from the Stream class, so all methods known from Serial should work.
If there is no telnet client connected the output is stored in a buffer.
Once a client connects, the buffer is send before live data.
So the printf's during startup can be observed later on.
#include <SerialViaTelnet.h>
setup() {
SerialTelnet.begin(115200);
SerialTelnet.println("my setup code is running");
}
loop() {
SerialTelnet.loop();
}
SerialTelnet.printf("example %d\n", x);
#define Serial SerialTelnet
Serial.printf("example %d\n", x);
SerialTelnet.HWSerial.printf("example %d\n", x);
CFG_CR
println() already appends \r\n to the line - nothing done.
printf("\n") results in \n. CFG_CR substitude \n with \r\n
CFG_FLUSH_RX
Any input data were flushed when loop() is called.
available(), peek() or read() will return wrong results.
CFG_SEND_INFO
Additional information is send on connect and whenever data is send to the ESP see emitInfo(). If CFG_HW_SERIAL is disabled the information is send whenever a line is received.
CFG_HW_SERIAL
The hardware UART can be used via HWSerial when Serial is overwritten by #define.
SerialTelnet.HWSerial.println()
