"Due to code size, on-board logging is not supported on the 1280. Telemetry logs can be made on your PC. Feel free to modify the code for yourself though!"

"Thank you very much for your help, I will join the group that you say and will try to learn, I have now a multicopter y6 with firmware 2.5.3 and apm1280"

"Yeah, I have one too Jose and I just now have the 2560 board and now everybody has the APM 2! It is a fast moving movement into the technology and it is advancing very fast! There is stable code for the 1280 (I can't remember what ver off hand)…"

"No, could you please explain?. my 1280 is outdated too fast for me. thank you very much"

"Do you know how to use the Arduino IDE?"

"anyone?"

"Could you explain how to do that please? thanks"

"The old 1280s (now retired more than a year) are no longer supported in the Mission Planner, but you can load the code via Arduino if you turn off datalogging and the CLI to save memory. "

"In the APM Planner, go to Terminal, hit Enter 3 times, type in logs.  You should see the list of items that are being logged.  altitude_mid is the item that suppose to log the altitude data and it suppose to be there already. "

"what APM2 open source, can be programming with Arduino"

"yes,,,thank jason..."

"The rangefinder library is what your looking for. There is also a mode library used to filter the results."
