Dear all,

I finally managed to get the OpenLog telemetry export always working (or not !).

It seems that the ETS Airspeed sensor is the source of the problem. 

Without the ETS Airspeed sensor connected the exports are always ok, with the ETS connected, exports always fail.

With the ETS connected, if I disable the AIRSPEED_ETS telemetry message, then the export works.

File sw/airborne/modules/sensors/airspeed_ets.c: 

#DOWNLINK_SEND_AIRSPEED_ETS (DefaultChannel, DefaultDevice, &airspeed_ets_raw, &airspeed_ets_offset, &airspeed_ets);

If I leave the AIRSPEED_ETS telemetry message, I got  "Fatal error: exception Failure("Pprz.values_of_payload, too many bytes: 11 03...." when executing getopenlog.

I tried to set &airspeed_ets_raw, &airspeed_ets_offset, &airspeed_ets to 0, but the same problem occurs. There is something with the telemetry message format / parsing.

Of course, I did a make clean; make of paparazzi.

Do anyone experienced the same problem ? 

Regards,

Mitchell

Dear all,

I have an OpenLog connected to a Lisa/M for onboard data logging.

I have added the OpenLog module to the airframe config file, the files are well created on the sdcard, but the export rarely works.

Here is below two exports tries: the first one is successful, and the second one is not. 

This was with the same setup, the difference is that on the first log the plane was not flying, but on the bench only.

First try (successful):

$ sw/logalizer/getopenlog ../data/logs/LOG00118.TXT 

now converting ../data/logs/LOG00118.TXT to ../data/logs/LOG00118.TXT.tlm

The conversion from the logfile from the SD to TLM seems to be successful, 1271 have been converted, 1 packages have been broken

Renaming produced file ...

$ sw/logalizer/getopenlog ../data/logs/data_helsinki.txt 

now converting ../data/logs/data_helsinki.txt to ../data/logs/data_helsinki.txt.tlm

The conversion from the logfile from the SD to TLM seems to be successful, 12063 have been converted, 0 packages have been broken

Fatal error: exception Failure("Pprz.values_of_payload, too many bytes: 11 03 66 05 00 00 00 00 00 00 00 00 80 25 24 39 99 0e 03 39 1a f5 00 00 00 00 00 00 59 3c 99 0e 03 2a 00 00 00 00 00 00 00 00 3b 32 99 11 03 69 05 e8 03 fa 05 be 05 dc 05 d0 07 e7 09 99 0e 03 39 71 9d 00 00

Do you have any idea of where I should look at in order to sort out that problem ?

Thanks.

Regards,

Mitchell
