no mav data solution #121

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
for all people who have the no mav data issue:

you have to disable either BRD_SER1_RTSCTS or BRD_SER2_RTSCTS by setting it to 
0 (or maybe both). i had this problem a year ago already and it drove me almost 
crazy back then. still amazed that so many people have that issue as it doesn't 
seem to be properly documented. somebody maybe add this into this wiki under 
apm settings?

see this link for more info: 
http://ardupilot.com/forum/viewtopic.php?f=72&t=8321 stefang advises against 
disabling it but it's the only solution that worked for me. let me know if 
you're still having issues with it...

also make sure you have disabled the "apm-reset" option disabled under 
config/tuning under planner before you set the sr1 or sr2 params, otherwise 
mission planner will reset them next time you connect

Yes there is somthing wrong with the APM latest software as it is telling me 
that it is trying to change parameters that are not there? eg,SR3 parameters 
when it lists SR1 parameters.I know that SR1 and SR3 are the same but it seems 
the APM isn't aware of this!.I'm trying to load some older software but this 
often means Mavlink 0.9 protacol so I'll go back on the Minim-Extra OSD 
software as well and see if this makes any difference.I'll report back if it 
solve's the issue of no mavlink data coming out of apm 2.6 with telem connected.

What do we do if we get this error but we don't have PixHawk, but APM instead? 
(thus we don't have BRD_SER1_RTSCTS or BRD_SER2_RTSCTS to disable)? I have 
tried MinimOsd_Extra_Copter_R800 as well.  I can't get this error message to go 
away.

I had the same problem when trying to use the arducam extra software yesterday. 
 I had it connected to Telem 2 on a Pixhawk with arducopter 3.2.1.  I was 
unable to get anything other than No Mav data with the recent firmware images 
(r719 and newer) up to r800.  Throughout this process the yellow heartbeat LED 
would blink when connected to the pixhawk which makes me think it's some sort 
of software issue.  As soon as I downgraded back to the regular MinimOSD 
firmware (v2 stable) it worked fine.  I tried with all combinations of the 
RTSCTS values set, and none of them made any difference.

Same issue as #4. I have 3 Pixhawk with Firmware 3.2.1 and they only work with 
MinimOSD V2 stable and MinimOSD V2.2 Copter. Connected to Pixhawk: no mav data. 
On the only APM with Firmware 3.2.1: Minim-Extra-R800-Copter works perfect. Is 
there any idea? RTSCTS changes does not made a difference.
