Re: Ethernet to Bluetooth Bridge

It looks as if the ESP32-BLE2MQTT project on Github does more or less exactly what I need. I am currently trying to build and install this on a LILYGO® TTGO T-Internet-POE ESP32-WROOM LAN8720A board. Once this is working, I should be able to control my Bluetooth radiator valves (several different ma...

Getting Started with ESP32

I am trying to download an ESP32 project from Github and build and flash it. The project is ESP32-BLE2MQTT. I could not get ESP-IDF to install (on my Windows 8.1 PC) by itself, so now I am trying to use Eclipse. I am not sure that I have the necessary toolchain installed in Eclipse. How do I check t...

OneWire master and slave

Has anyone implemented the Dallas/Maxim OneWire (1-Wire) protocol on an ESP? I need to build a OneWire hub (to enable me to connect multiple OneWire buses to a single OneWire master such as the DS9490R). This no longer seems easy since Maxim stopped making the DS2409. The best way forward in the abs...

Ethernet to Bluetooth Bridge

I need to connect a number of Bluetooth radiator valves to my home network. I have not been able to find a cost effective LAN to Bluetooth bridge, so I think I will have to create this for myself. This could be done either via WiFi or via wired ethernet. Is ESP32 a good way to do this? Is there code...

Re: Getting Started

That sorted it thank you. Yes, there are two buttons on the board (marked Boot, and EN), as well as an On/Off switch. I had to press the Boot button, then it started to load correctly, and the sketch ran successfully. Why isn;t this mentioned in the official documentation somewhere? Or have I just n...

Getting Started

I have an ESP32 development board made by DIYmore. If I power it up the blue LED flashes, and the red LED is permanently on. I have tried loading a sketch from the Arduino IDE, but I get this: Sketch uses 599086 bytes (45%) of program storage space. Maximum is 1310720 bytes. Global variables use 414...
