Re: Root node selection and espconn_mesh_enable()

3. Let's assume a group of three nodes which are normal nodes and are connected to the root node. Now if this group of three nodes are moved far away out of the range of the root node and also out of the range of the internet router then what will happen?

The 4 modules are sending data to the server and receiving the 'echo' response. I've some question that hope yo...

Hi, I'm using crosstool-NG as a compiler and esptool.py as flasher. I read from "esp_starting_guide" that the memory positions to write these two file are 0x00000 and 0x40000, respectively. Nevertheless, every time I did that I was getting "fatal exception(28)" through serial int...
