Using IOT TEL0126 to Make Arduino Web Server
Anthony.Roberts 2025-11-03 11:16:08 343 Views3 Replies Based on the instruction set and examples https://github.com/DFRobot/DFRobot_WiFi_IoT_Module/blob/master/README.md for DFRobot's TEL0126 IOT Wifi Module, functionality seems explicitly only for use in limited IOT applications. But I wonder with the hardware capability of the module, is there flexibility to use in broader networking applications? Can I use it to make/send web requests over my own network even within the limited command set?
I once struggled to host a simple Arduino server while balancing countless sensor inputs. Your explanation clarifies what took me hours to untangle, especially setting up stable communication through IOT TEL0126. Sharing this to Slice Master really feels like passing along a key tool every maker should keep in their kit of experiments.
Matthew.John9877 If you’re comfortable with firmware flashing, you could:
Connect the TEL0126’s UART to a USB–UART adapter.
Use the ESP8266 flashing tool (esptool.py) to replace the DFRobot firmware with:
ESP8266 Arduino Core
NodeMCU (Lua)
MicroPython
Or your own custom firmware using the ESP SDK.
ahsrab.rifat Hello,
Thanks for the reply. Sorry for the delay, I was exploring options and including looking at your suggestion including by checking out Espressif's website (makes the ESP32-D0WD on the TEL0126. Is there a reason the firmware on this device would prohibit me from using it to build a web server? After I looked up the chip, I see it is an especilly capable device with dual band wifi and bluetooth. I would assume I could use it just like a shield for the arduino and even tried the WIFININA library for the discontinued Arduino library shield.
