#73 Serial Monitoring your Arduino or ESP8266 with Putty (Tutorial)

In this video I show how you can monitor two or more serial lines in your projects. This can be necessary if you connect a GPS or GSM module to your board. I use Putty for this purpose

Interesting AND useful! Thanks for sharing that Andreas!

uhuu... Good leson!! THANKS Very Much. From Brazil.

Again, nice video from the guy with the swiss accent. :-) ave you ever tried using Linux? In my experience, developing is much easier there, handling serial ports is less complicated and no additional drivers are ever needed.

Can you show us how to test a ESP8266 TCP/UDP connection using Putty. That would be really interesting. Thank you for your lovely videos.

The new Nextion libraries have hardcoded a baud rate for the nexSerial interface in NexHardware.cpp. This makes it ignore/reset anything you specify before nexInit(). I just now tracked down this 'problem' after finding this video. I've since changed the default baud in the library to 115200 and no longer use Serial2.begin in my esp32 code. Glad that neither of my devices have a hardware failure.

Great video! I'm curious if you have verified that the 3.3v switch selection on the CH340G UART module actually level shifts the TX line to 3.3v. I have seen some adapters that the Vcc output line lowers to 3.3v but the TX line is still at 5v.

Thanks for the videos. Two questions though, 1- Is PuTTY the best available software for serial monitoring? I've used RealTerm for a while and it's nice but its terminal showing the serial data is quite lacking and frustrating.

thanks for you videos, i have question, is there a possibility to make nextion display like a serial monitor of arduino?

I greatly enjoy your tutorials including this one on adding a serial monitor. Would appreciate your thoughts on this application: I am passing serial data from Arduino to Python. This prohibits me from watching the arduino serial monitor or plotter (since Arduino would then be unable to communicate with Python). Would any of your suggestions in this tutorial allow me to visualize data on a second serial monitor/plotter while at the same time sending data from Arduino to python on the 1st serial monitor? Also, it appears to me that Putty allows serial monitor but not serial plotter. Is there a way of using a second serial connection as a serial plotter? Thanks, Mike

I suggest not to use USB to TTL converters with FTDI chips, because there are so many fake ones and you get trouble with the drivers. Instead use the CP2104 that are recommended by lady ada to!

Again a very good video!

simpel - auf die idee muss man erst kommen !!
hut ab vor deinen filmen!!!

Great thing about a terminal app is you can use ansi for colors and bell, and cursor control

[jamesmaxwell]

And 2- Wouldn't using multiple TX/RX lines on a single UART connection cause loading effects or introduce noise depending on the circuits of the modules?

[shvideo]

Great video. To summarize then, if using an Arduino Uno, are all these true?

1. Connect the Arduino to the PC using the USB cable and then use Putty on the PC to send and receive characters to and from Arduino?

2. Connect the Arduino through TX0 and RX0 pins to a USB serial adapter, connect the USB serial adapter through a USB cable to PC and connect putty on the PC to send and receive characters to and from Arduino?

3. Cannot do both because there is only one serial device.

Thank you in advance.

Hi Andreas, I don't know if the question is consistent with this video, however: I'm using an FTDI adapter, a WROOM-02 and an Arduino IDE. My question is if I can and how, via my pc, I can send and receive AT commands via Putty while in WROOM-02 is running a sketch
Thank you

Issues with the Wemos esp8266(clone ) This was easy with my Nano. Realy nice debug workaround when wanting to use the hw serial pins. Though, I'm having issues getting my Wemos esp8266 to output anything to the serial console by way of the SW serial assigned pins. I've tried SoftwareSerial mySerial(13, 15) for GIOP (D7, D8) Silkscreen on the board. both compile. Thoughts, suggestions?

Sehr schönes Video, ich wusste gar nicht das Putty auch sowas kann.
H-Therm ist mein Lieblings-Terminal Programm wenn ein einfaches nicht mehr ausreicht.
Man hat bei h-term sogar einen Timestamp wann was gesendet wurde und kann damit messen wie schnell eine Antwort kommt

if a simple terminal is not enough

Hi Andreas ! There is a book in witch I can read what you say ? I have difficulties to understand the English spoken but I like it very much ? I want to made for myself a wifi meteo station with ESP 8266 and it is perfect . Thank you, Ion

[Fifury]

No I just have to figure out how to redirect the output to an excel spreadsheet or web page over a WiFi connection on an ESP8266!

Good ol' PuTTY... Is there anything it can't connect to? I originally got it for SSH, but almost any communication task I come up against, I find PuTTY will effortlessly fill the bill.
