Using IOT TEL0126 to Make Arduino Web Server
Anthony.Roberts 2025-11-03 11:16:08 514 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 ** 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.
