Serial WiFi Terminal Customer Insights

1. I used it to connect to the telnet server of the NodeMcu board (the WiFiTelnetToSerial example sketch of the ESP8266WiFi library for Adrduino IDE) and it worked well (like many other TCP terminal clients do..). My question is this: Why emphasize 'serial' and 'wifi' in the name of this program since most of the heavy lifting is server/microcontroller side anyway? How is your software different (and I mean 'the extras') from a regular telnet cient?Thank you but I have a problem.

2. I tried all of the protocols but every time it says "connection refused" Is it related to the port? Cause I don't know which port I should choose.Simple and solid app, does everything you'd want it to.

3. Any suggestions?Suggestion for new feature: When clicking on name/ip address in the Devices tab, have the program switch to the terminal screen and try to connect.

4. Amazing job 💞Great app! But lacks the ability to store binary data to file, thus need to stream as hex, then convert to bin..Great app for Telnet.

5. Thanks so much for writing such a nice tool, and for making it available to us.Is this supposed to work PHONE 2 PHONE??? i am on same network.

6. I tried port 80 12345 I tried telnet.

7. Both phones see the other phone in DEVICES aok.

8. I pick other phone on both terminals.

9. It's the only Android app I could find that can talks to my Pentair pump through RS485 to wifi that I had installed.

10. Could add this to the settings tabUse it to connect to ESP32 server onto a raw socket.

11. I love that it doesn't close when multitasking with other apps.
