ER9x + Rolling SW + Mavlink + PC Control ?
Hello Everybody,
i have two questions which hopefully somebody can answer:
First question:
- If i have a PC and a TG9x with the ER9x- Ardupilot Firmware, is it possible to connect both the PC (Mission Planner) as well as the Remote Control (TG9x) to the Ardupilot at the same time ?
-> E.g. by running a Cable from the TG9x to the PC and using the same modem ? - In other words, can mavlink be used multipoint ? - Or is it only point to point ? - If so, how would i wire TX and RX ?
Second question:
- Is there a software version for the ER9x which supports also rolling switches ? - I have tried the normal ER9x, but it seems not to support e.g. to use the TRN switch as rolling switch like the SW version from GerardV. - Anyone got an idea ?
I would really highly appreciate an answer on this.
Cheers
Florian

Looks like I am receiving data.
I am set to 57kb
Now I'm getting 0x55 0x03 ......etc
here is pics.

Hi,
How do you solve your problem before this ? UART Baud rate or TTL Level ?
Not receiving heartbeat :
Really I dont know, to investigate we need more dump,
you can use "Free serial port monitor 3.31", but do not use MegaPlanner to generate data but a dumb terminal.

More pics.
Where do you want to see the data from ? Also, maybe the data stream is too fast for the er9x.

GOT IT !!!
It was the baud rate. When I changed the APM2 and all the Xbee's to 38kb it all started working.
Now to find out why 56kb won't work.

IDK if I said this. I am using the purple APM2 board.
The 57kb problem must be some little timing error. I will try to trace it down.
When I get time I will post the source code for mavlink on the er9x site if it is ok with you.
I will call it er9xMavLink
Now it's back to school Monday. Spring break is over. Hard on a 65yo that went back to school to become an astrophysicist !

Great Earl,
It work now on APM2 and xbee.
Yes you can put this code on er9x, but it work on ArduCopter, not on ArduPlane.
I am younger than you, only 52 springs :)

How about er9xMavLinkAC
With plane I will name it er9xMavLinkAP
Hope to get the 57kb working.
Well, I am off to my physics lab.

Yea !! Works with APM2.0 board and version 2.30 of arduplane if you change the baud rate of serial3 to 38400 !

Tried with Mission Planner 1.1.59 and Ardupilot 2.3.2 works at 38kb good.
Works at 38kb on Arducopter 2.5.3 well also.
I have not checked 57kb lately. I don't know what com library they used to compile the hex code on 2.3.2 or 2.5.3
Hope your around this weekend !

Hi !
I hope to get this working also with 56 k in the end as i want to use joystick control via MavLink in addition to the remote - so this will likely cause too high latency.Unfortunately it looks like that i will get only to test this in a few days.
Lets see. Does anybody know where the sources of the GV9x are ? - I could only find hex files - or do you think the problem is only in the APM 2.0 ?
Cheers
