Crash Report

I experienced my 2nd crash with my APM2.5 last evening. The first crash destroyed a super sky surfer then last night destroyed an X8 Wing. The exact same scenario. Took off in manual mode (never…Continue

"@Andreas
I have loaded your ArduCopter code to my APM2.5 and have it running connected to my PC via USB. I have my droncell clone (icomsat1.1) connected to my APM2.5. What I can't figure out is how to accomplish step 6 above - how do I change…"
Jeffrey Nichols replied to Jeffrey Nichols's discussion Isolate GSM Shield to 2nd arduino? in the group Telemetry over cellular IP"I can get it to send SMS messages & register an IP. Yes, UDP is bi-directional and commonly used in multiplayer gaming where fast tx & rx is required and packet loss is acceptable. "
Veikko Vierola replied to Jeffrey Nichols's discussion Isolate GSM Shield to 2nd arduino? in the group Telemetry over cellular IP"Before you start to program the arduino, try to make the DroneCell work using FTDI cable and direct AT commands with terminal program, once you are able to give DroneCell AT-commands manually that make the dronecell work…"
Jeffrey Nichols added a discussion to the group Telemetry over cellular IPIsolate GSM Shield to 2nd arduino?
I'm considering a unique approach that will lower the barrier of entry (programming skills, etc) to this segment. That is to take my GMS shield and put it on a 2nd arduino (uno) and attach it to the serial connections of the APM2.5. This approach will allow one to use the latest version of Mission Planner while only adding a small bit of extra hardware to their setup. Once the sketch to enable the serial over UDP connection is working, the code on the UNO can be left alone.I'm interested to…See More
Jeffrey Nichols replied to Jeffrey Nichols's discussion Crash Report"For anyone finding this thread later on I wanted to report the final outcome. I have since installed this same unit in another airframe and it works fine. I'm pretty sure I had made a mistake during the radio calibration phase for the other two…"
Jeffrey Nichols commented on james sowell's group X8"@John - they changed the wood bits that come with the kit - it's really a tiny change. Also, if you modify the wing so that the trailing edge lines up with the fuse you'll actually require less trim and make the airframe more efficient. I…"

Andke replied to Jeffrey Nichols's discussion iComSat v1.1 in the group Telemetry over cellular IP"Hi. I am travelling - but search this forum for my posts or replies + "dronecell" or GSM - and I 've also submitted it as a feature request in arduplane bugtracker - so it should be easy to find."
Veikko Vierola replied to Jeffrey Nichols's discussion iComSat v1.1 in the group Telemetry over cellular IP"Andke, I managed to get the UDP working on drone cell, but not TCP?? (And only with QGroundcontrol, not with the Mission Planner...
Could you send the initial modem commands that u used to get the Dronecell work as TCP server and feeding the serial…"
Andke replied to Jeffrey Nichols's discussion iComSat v1.1 in the group Telemetry over cellular IP"I tried TCP just because it was easy to get the S900D be a TCP server, display it's IP on a LCD, then enter the IP in the mission planner in-field.
when using UDP, it requires that SIM900 pushes packets to a known IP, so you need a permanent…"
Will Snodgrass replied to Jeffrey Nichols's discussion iComSat v1.1 in the group Telemetry over cellular IP"You would never want to use TCP in this kind of application. UDP works far better because TCP by nature makes sure that every packet gets there, and then is assembled in the right order before proceeding. That's good for documents and downloads…"
TUFAN OZBEK replied to Jeffrey Nichols's discussion iComSat v1.1 in the group Telemetry over cellular IP"you need to find tx rx pins
and learn "how can i start data connection and learn module ip adress and port"
and dont prefer tcp i think udp is faster from tcp"
