In this project We need only coordinate then We need only "$GPGGA"

GGA - essential fix data which provide 3D location and accuracy data.

     1            Fix quality: 0 = invalid
                               1 = GPS fix (SPS)
                               2 = DGPS fix
                               3 = PPS fix
          4 = Real Time Kinematic
          5 = Float RTK
                               6 = estimated (dead reckoning) (2.3 feature)
          7 = Manual input mode
          8 = Simulation mode
     08           Number of satellites being tracked
     0.9          Horizontal dilution of position
     545.4,M      Altitude, Meters, above mean sea level
     46.9,M       Height of geoid (mean sea level) above WGS84

     (empty field) time in seconds since last DGPS update
     (empty field) DGPS station ID number
     *47          the checksum data, always begins with *

If the height of geoid is missing then the altitude should be suspect. Some non-standard implementations report altitude with respect to the ellipsoid rather than geoid altitude. Some units do not report negative altitudes at all. This is the only sentence that reports altitude.

ESP8266 web server Home IOT

ESP8266

Use CH340G repalce the CP2102.

Open-source, Interactive, Programmable, Low cost, Simple, Smart, WI-FI enabled

FOR Arduino like hardware IO

Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.

Code like FOR arduino, but interactively in Lua script.

Nodejs style network API

Event-driven API for network applicaitons,

which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style.

Greatly speed up your IOT application developing process.

Lowest cost WI-FI

Less than $3 WI-FI MCU ESP8266 integrated and esay to prototyping development kit.

We provide the best platform for IOT application development at the lowest cost.

ขั้นตอนการลงโปรแกรม และ ติดตั้ง

1. โหลดIDE เวอร์ชั่น 1.6.5 ถ้าตัวอื่นก็ลองดูได้ครับผมใช้ตัวนี้ โหลดจาก https://www.arduino.cc/en/Main/Software

เลื่อนลงมาอีกนิดจะมีให้เลือกเวอร์ชั่น

Previous Release

การติดตั้ง Board ESP8266IDE Sketch ที่แนะนำคือ เวอร์ชั่น 1.6.5
