Hi,

tried with newest version
first I had to remove "f" from airspeed * 10f, otherwise arduino sketch did not compile.
Now 9xr pro shows Aspd of 40 to 50 fluctuating which seems cool, however it is not 10th multiple of 0.8 to 1.8 m/s as meassured by APM.

Mike,

I tried newest verisons. Arudino did not want to compile so i removed "f" after airspeed * 10 (instead airspeed * 10f).
Now numbers fluctuate (40 to 50), but do not seem to be mutiple of 0,9 to 1,8, which is usual fluctuation when pitot tube is closed - not in flight).

Tried with mini pro 32k and return 5 test.
Aspd shows 0.

Mike: is it Aspd after TmOK value in custom telemetry menu, that should show airspeed?

tomi

Hi,

I tried return 5 test, and Aspd is still 0.

Will solder my new mini pro 32k after breakfast and test with it.

tomi

Hi,

tested the new code from github. Aspd still 0 on S.port x8r, mini pro 16, 9xr pro.

tomi

I am using SPort of x8r.

Hi,

i tried new firmware version on mini pro 16k and 9xrpro. Airspeed does not work. Value Aspd stays at 0 all the time, eventhough apm shows normal airspeed fluctuation (1.3 to 1.8 m/s) through Mission Planner. Other telemetry displays normally on 9xr pro display, so mini pro does work.

Tnx for new verison Mike.
I will try it over the weekned if the weather gets better.
There is so much wind lately...

tomi

Airspeed is measured by APM airspeed sensor (optional hardware). GPS speed is actually a groundspeed. Airspeed and groundspeed are not the same if there is wind.

tomi

Hi,

Mike would it be possible to add airspeed reading from apm to ersky9x(r)?

tnx.

tomi

Nano does not work. Tested. Many times...
Mike has written an explanation for this several pages back in this thread.
My suggestion is to save time (I did not...) and buy cheap mini pro, which works well. Both 16k and 32k minis work but I suggest 32k in case the code gets bigger.

Hi, Mike, I have tested new firmware on 9xr pro and arduino mini pro 16k, frsky xjt/x8r combo, amp 2.6 clone. I confirm six modes that I have programed in arduplane are recognised and displayed correctly:auto, manual, fbwa, fbwb, loiter and rtl. On debug screen (6/10) in the last row there is only o...

Hello,

Mike, have you had any progress on correct arduplane apm modes naming on ersky9x(r) display?

Hi, came home from skiing holiday. My brother any I have tested mini pro 16k with newest firmware and it works OK! It however shows unknown APM mode for manual, flyby wire A and flyby wire B modes, that are standard in arduplane (not arducopter), while in arducopter modes are recognised OK. Is it po...

Hi,

I will not be able to test 16k mini pro for at least a week, since I don't have nano which has been used for programing mini pro at home any more.

I expect to get 32k version and my own FTDI programmer in 14 days. I will try also with 16k then.

tomi

I still don't understand TmOK.
if TmOK=2 (=arduino to s.port working properly), but if all variables on telemetry screen are 0, apm is not sending data (=apm to arduino not wokring) despite TmOK=2?

tomi

I guess I will wait for my mini pro 328 to get from China. It will take two more weeks.
I will test with it, as 16k version might not work due to its limitations.

tomi

Mike,

do you think we have problem because using 16k version of mini pro? During compile it warns, that only 112 bytes is left for variables.
How can I test if mini is getting mavlink messages from apm?
What is the meaning of TmOK 0, 1 and 2? DO the work if there is no mavlink from APM?

tomi

TmOK shows 2. If i disconnect power to apm and x8r TmOK shows 1. I am still not sure that apm is sending out the telemetry. We tried to confrim that with two osd devices (minimOSD and ramzebi), but somehow it didn't work even without arduino connected. It was working before, but not today. Strange. ...

Ok after tests with two different sets of 9xr pro, xjt, x8r, apm 2.6 and wires we have consistent conclusions (the same behaviour on both sets): arduino nano does not work. arduino mini pro 168 5V 16MHz seems to connect. After apm starts sending telemetry data, diasrmed is shown on telemetry screen,...

Ok, so you think it should work with mini pro? Does it have the same resistor as nano? Have you made any config settings in mission planner on the apm before it worked? Should I use 1.5.8 IDE instead of 1.6.7? In two hours, I will run some more tests, when my brother is coming with his equipment. An...

Double checked the connections and connectors. They are fine. Regarding nano led lights: when I power it up, green led power is lit, and after apm 2.6 intializes green tx light starts blinking every second, but red rx light does not blink at all. I guess this is a problem. For test I have connected ...

NO DATA blinking on mavlink screen of ersky9xr: tested with 9xr pro xjt and x8r modules arduino nano apm 2.6 compiled with arduino ide 1.6.7, uploaded without errors ground connected to d2 pin on nano (to activate s.port) signal of s.port connected to d5 apm powered by usb 220v to 5v adapter (should...

Cool,

do you think the code would fit to 16k (which I have at home now) or it is necessary to have 32k mini pro (which is coming from China...)

tomi

Nano is just mini pro with usb circuitry onboard. I guess...

Do you connect on s.port or hub?

tomi

These are great news Mike! Keep up the good work.

Please tell me which arduino do you use for converter, as I have tried nano again with all existing software, but did not get anything to work.
I have x8r so I need s.port connection.

tnx

tomi

Hi, Mike, i have already posted a comment and a question in other topic in ersky9xr forum, but this thread seems more appropriate. here are the links of "working" arduino mini pro and nano interfaces to s.port of frsky, however they didn't work for me out of the box. Much cheaper solutions...

Hi, i loaded new firmware r219c. It says this is a start for MAVLINK telemetry. I have found project on arduino mini pro. https://github.com/rotcehdnih/Mavlink2Frsky/commit/37d429bcff4f0f962606c44f159ed22769a62eb2 I connected my apm 2.6 to arduino nano (i also have mini pro but atm168 not 328,so cou...
