Missing documentation on how to connect ESP8266 modul to Arduino for this library

[horejsek]

I have Arduino Nano and ESP8266 ESP-01 module. I want to use InfluxDB client library but it cannot connect. I did not figure out to which pins I should mount the module, or where I should define it in the code. Whatever I try, I get esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header.

@horejsek, this library is intended for use when programming directly ESP devices with their Arduino SDKs (Arduino core for the ESP32 and Arduino core for ESP8266 WiFi chip.

Using an ESP device as a WiFi peripheral device is not currently supported.

However, writing to the InfluxDB server is easy. For writing data to local server you just need to send a single HTTP POST request. See https://docs.influxdata.com/influxdb/v1.8/guides/write_data/ for more details You will probably find many examples how to construct HTTP POST request when using an ESP as a peripheral device.

I see, thanks! Maybe it would be good to make it clear in readme.
