Installation
|
|
------------
|
|
|
|
Official esptool
|
|
================
|
|
|
|
The prefered option for flashing esp8266 device is via the official esptool. Documentation can be found
|
|
here; `esptool home page <https://docs.espressif.com/projects/esptool/en/latest/esp32/>`_
|
|
|
|
Windows 10 should install a driver for the USB -> Serial automatically when you connect a esp8266.
|
|
|
|
Flashing on windows
|
|
*******************
|
|
|
|
The basic command for flashing on Windows is;
|
|
|
|
``esptool.py --port COM4 write_flash 0x0 firmware.bin``
|
|
|
|
If there are issues you can try do erase the flash first using this command;
|
|
|
|
``esptool.py --port COM4 erase_flash``
|
|
|
|
Serial Monitoring
|
|
*******************
|
|
|
|
To check output from the device (logs) there are several tools out there. I found this simple tool in the Windows Store called ``Serial Port Monitoring``.
|
|
Just select a baud rate of 115200, 8N1.

Binaries
|
|
********
|
|
|
|
In the /bin directory you will find 2 different firmware builds;
|
|
|
|
* **firmware.bin**
|
|
|
|
This is the standard release build (prefered version)
|
|
|
|
* **firmware-perf.bin**
|
|
|
|
This version also submits performance data to an influx database with detailed execution times.
|
|
|
|
|
|
In these versions all the html files are embedded in the binaries. The file system is currently only used for storing
|
|
the configuration file.
|
|
|
|
If the software becomes so large the html files can be moved to the file system, but this is not enabled by
|
|
default (see compiling for details). This approach makes installation much easier and ensure that html files
|
|
and code is in sync.
|
|

|
Configuring WIFI
|
|
================
|
|
|
|
When the device is flashed it will need to have WIFI configuration in order to work. If you have used other software on
|
|
the device its possible that wifi settings exist.
|
|
|
|
If this is not configured in the device it will create an wirless access point called `GravMon`. Connect to this AP and
|
|
enter the SSID and password you want to use. If the web page dont open automatically you can enter the following adress
|
|
in the browser: **http://192.168.4.1**
