"I have an Oktokopter 2 that flies within the 250m radius waypoints. I have looked at the Ardupilot board and am interested in implementing the solution to fly beyond this limit you mentioned Sebastian. If you have any more details on this…"

"No, that just means you need to set it to radio type 1. All this is covered in the manual."

"ok, got it wrong, the wi232 has more range than the xbee 2,4 ghz module. I don't know anything about the 868, I also don't know how to configure it. Probably both have to be in the same VID."

"here you see a screenshot: http://www.makingthings.com/documentation/how-to/update-xbee-settings-with-x-ctu/xctu.png - "Modem Configuration" - "Read" - then change settings - "Write" then test communication using the…"

"the modul ist fast enough, important is to have it setup at 57600. by clicking on "Read" you can read the settings. I use the Wi.232 Module, which has more range."

"the MK guys will not help and there is nothing in the works. you can compile the NaviCtrl source, but some functions in GPS.c are missing. A different approach would be just to implement those functions, to have unlimited navigation. My ardupilot…"

"I've read some strange and cryptic post regarding new NaviCtrl routines but the guy who was leading the charge on the front suddenly halted his work. He claimed that he spoke directly with the MK folks... and it seemed that something might be…"

"there are several ways, but I do not have something done yet. What I do right now: I attached a simple ardupilot hardware ($24) to the mikrokopter. (without any sensors) I connected that ardupilot UART to the NaviCtrl of the mikrokopter. Via the…"

"Sebastian, I've just ordered a Hexakopter and would like to know how to circumvent the 250 limit. What can you tell me about it. Thanks, Sam"

"the problem was, that the em406 code initializes the GPS with 57600, but ardupilot assumes that the arduimu runs with 38400. so either change the em406 code in arduimu to initialize the gps with 38400 or change ardupilot to connect to arduimu with…"

"so I finally got it…"

"ups... it is supposed to look like this, not an error."

"here are my oberservations: I changed the code in GPS_EM406 to just output every byte it receives from the GPS: ------------- if(Serial.available() > 0)//Ok, let me see, the buffer is empty? { Serial.println("***** there is someting…"

"yes, I use the HiSight and it works pretty good. The advantage of the HiSight is, that it's pretty light. But you can easily something similar."
