Pete's script works great. You just need a serial output log (via Xbee telemetry) to parse with his python script.

Hi May i ask. What was the final outcome? I would really like to be able to log my flights. I'm still a UAV/programmer noob... So please just explain it step by step.

Are you using level converters if they are 3.3v TTL radios ? you need to cross the rx-tx one side , I had similar issue , once connected via logic converter and respective power supply system , the data radios started working.

xTend Modules

Hello All, I have been in the process of trying to use a set of 1W xTend modules for telemetry with the ardupilot. They have been configured to the correct baud rate settings and can communicate to each other through XCTU, but they receive nothing when connected to the ardupilot. Is anybody else using a set up similar to this or have any ideas of what might be going on? Are there any other settings (other than baud rate) which need to be configured differently?(I have been connecting the tx pin…See More

John, Reviewed and uploaded to the repository. I made a small change. If TOW is not there, there it not now considered an error. This makes the change compatible with any Ardustation telemetry that does not have TOW for now. # JOHNC…

Hi John, That is super. I'm delighted that you have started to understand the code. Adding time meta data to the KML will be a big step forward. Getting something working initially may not be too much work. (I've not looked at the KML…

looks like I may have gotten it in there. I just added this in the Ardustation telemetry parsing above the LAT parse: match = re.match(".*TOW:(.*?),",line) # Time of week if match : self.tm = float (match.group(1)) # Compatibility else…

John, Adam Barrow had the same idea. It is the right way forward, I agree. Are you already parsing the TOW field ? I can add it to the ardustation telemetry parser in just a few minutes if you want it in the code. Alternatively, if you send me a…

Thanks for the work Pete. It's looking good! I recently added the Time of Week output to my flight logs. ie: !!!TOW:422022750,LAT:32248268,LON:-110833968,SPD:27.76,CRT:0.00,ALT:66,ALH:50,CRS:126.28,BER:218,WPN:0,DST:455,BTV:0.00,RSP:35,*** I…

Pete Hollands replied to Colin Ho's discussion 'datalogging'

John, I've posted a fix for that filename replacement bug in the code repository. I also added colour coding of Ardustation Telemetry waypoint routes. The code is still not finished yet for Ardustation, but it's becoming useful now. So…

excellent....just needed to rename it to .txt thanks!

Pete Hollands replied to Colin Ho's discussion 'datalogging'

That is not a good bug. Please could you rename the input file to udal_flight_log.txt I'll have a look at replicating that bug on my machine and fixing the code as a priority tonight. Thanks, Pete

Thanks Pete, I didn't know it relied on X. I also have python installed on my XP machine. I could use a little help. This is my current dir structure: I double click on the .py script, and get this dialog. I then double-click my .log…

John the best way to test remote application display back to your screen with X and Linux is to use the program xeyes. xeyes is a small trivial test program that comes with the X distribution. The easiest way to get this working is to have X…
