Steve Cain replied to Andre's discussion Taranis / FrSky X8R Sbus issue with Pixhawk
"I use various FRSKY receivers with all my Pixhawks... all work perfectly including on 3.3 RC7

Note that the X8R sends telemetry back to the Taranis... In some cases if the X8R receiver is too close to the your GPS, you may get less satelites as the…"

"With RC5 I now get the error message "Error EKF POS VERT AGL" all the time.  The quad (550 H Frame) flies fine in loiter, position, stabilize.

"3.2 fly away today. (logs attached)
here's what happened. - this is my 5th 3DR quad (4th pixhawk quad) I have hundreds of successful flights logged.
The quad is a QX 350 frame with a pixhawk in it, 2212-920 motors, no gimbal 4000mAh 3s weighs 1Kg.…"

"Jake,
as I stated above the legal limits for un licensed operation in the 433 mHz band are 100mW. Actually that figure is a bit dumbed down for the forum.  The actual legal limits for unlicensed emission are found in the CFR 47 part 15.209.  which…"

"Jake my numbers are backed up with hundreds of hours of flight time.  As for legal power emission, I can transmit up to 1500 watts on all the frequencies mentioned above because I am licensed ham radio operator in the US.  

FWIW, all the…"

"Try a 433 mhz control link.   Nominal power is 150 to 200mw which is good for more than 5 miles in the real world.   not enough power?   Switch to high power (now you have 500 to 600mw... 6dB more power)  still not enough power?   Buy an external 2w…"

"I noticed this with the Exuhf in my Taranis.  If channel 4 (rudder ... used for arming and disarming) is moved all the way right (more than 2ms) then mode on the HUD (and OSD) would change to RTL as the Pixhawk lost sync on the PPM stream.

Steve Cain replied to Randy's discussion ArduCopter-3.2 beta testing
"The timing of the rc pulse stream can experience problems if the pulse width exceeds 2ms.  This happens because the 2ms pulse hasnt ended before the next pulse starts.   This problem can occur in the ppm stream decoded in the pixhawk or in the rc…"

Steve Cain replied to Randy's discussion ArduCopter-3.2 beta testing
"There is nothing to address, the code is doing what it should.  Instead of adjusting the tx trim, you may consider setting the throttle travel (on the "servo's" page in the FrSky to a lower number, say 80% ) so that at center trim, the pulse widthis…"

"Artem,
Do you have the parameter list for the SR0, SR1, SR2?  I can't find them documented anywhere... I guessed and set SR2 all the same as SR1, which makes the minimosd happy but have no idea what these parameters actually are...  appreciate any…"
