There are so many firmware that could be working as telemetry for pixhawk. the orignal one, https://github.com/liqin123/UAV-wifi-link the way of making upload is a complex, you need to load 3 different bin to 3 different address. So I did not try it. https://github.com/dogmaphobic/mavesp8266 This firmware takes mavlink command to setup the wifi...but I tried Qgroundcontrol v3.2.5and mission planner 1.3.5 QGC will have a esp8266 section when you connect through wifi when it's a AP.. MP will show the ESP8266 stuff, when you connect through usb.... but both not working with mavesp8266 mavesp8266 also have a http command, but I can't get it work as station.... but this is the current one that I have it worked. it's done with platformIo, so there is a way to make it as station form source. 2017/12/7 I update again the ESP8266 firmware with mavesp, and connect on pixhawk mini(this one also updated to arduplane 3.8.3), it should first show up as AP, connect wifi o...

mission planner follow me mode with external GPS

I wish to use follow me mode to make my 4 axis to follow a RC car or RC boat. the idea is to transmit decoded GPS location and pass through radio form remote site to station. And then pass the coordination the mission planner with NMEA format. which I will need to use a arduino and generate NMEA to USB. there is no lib for this, but a example of generate CRC: http://engineeringnotes.blogspot.tw/2015/02/generate-crc-for-nmea-strings-arduino.html for the sentences contain position: $GPGGA Name Example Data Description Sentence Identifier $GPGGA Global Positioning System Fix Data Time 170834 17:08:34 Z Latitude 4124.8963, N 41d 24.8963' N or 41d 24' 54" N Longitude 08151.6838, W 81d 51.6838' W or 81d 51' 41" W Fix Quality: - 0 = Invalid - 1 = GPS fix - 2 = DGPS fix 1 Data is from a GPS fix Number of Satellites 05 5 Satellites are in view Horizontal Dilution of Precision (HDOP) 1.5 Relative accuracy of horizontal position Altitude 280.2, ...
