#F5 DJI Roma - how to setup?
1 messages · Page 2 of 1
I was gonna ask if this is stupid
But I definately cant see the led here 😅
Ok so here's what I've got, I'll put some clear tape over the top so I can still see the led.. anyone see any issues with this? I didn't wanna touch the gyro , it looks like it would be too close up top
I'd run that
looks fine
seen way worse, don't worry lol
Thankyou , sorry for double checking every little thing :)
What do I do next? After cable ties
Have you gotten any further?
Everything is back together now, I plugged it in and contrary to what I believed it appears like the reciever is powered by the USB, I can move the sticks on the radio and see the sliders move in betaflight
But its horribly configured so I'm watching a tutorial on configuring my radio
Nice! You're super close then.
Are the channels swapped?
After that I guess its setting up the channels, ince I've done that I'll come back to you guys yo check my work 😅
I think the radio needs calibrating
I get a throttle warning when turning it in, even though the throttle is at 0
In regards to assigning switches to channels: CH5/AUX1 must be the ARM channel and be active at ~2000
That's an ELRS requirement
To assign a switch to a channel, all you need to do is to go into the Mixes page on the radio, create a mix on a channel (enter its editor) and set its Source to be the switch name. You can click the source to start editing it and then just flick the switch back and forth to make it select automatically.
Then, betaflight will see that switch on that channel. In BF you must tell it how channel values map to enabling modes. You do that in Modes tab.
In modes tab you basically tell it "when AUX# channel is between X and Y, enable this mode, otherwise turn it off"
in regards to incorrect channel mapping: on your radio, click the SYS button, page over to Radio Setup. Scroll all the way down, and verify that Mode is set to 2.
@rapid marsh ^ you should start with this last message
In mixes page you can see the channel order. First letters of channel names in order.
Aileron, elevon, throttle, rudder = AETR1234 in BF
In OpenTX, the default multirotor model only has the four main control channels mixed in; throttle, yaw, pitch, and roll. To get the radio to send the switch values as well, they need to be mixed in:
Go into the model setup, and page all the way to the mixers page
Scroll to the empty channel 5, and long press enter to make a new mix
You can o...
:)
@outer snow put it into the knowledge under a topic like OpenTX/EdgeTX Setup
okey
I think something happened to the original model I had on my TX16, I've created a new one, ensured the radio is on mode: 2
And have created a 5th channel for the arm button
Could I check a couple options with you all?
Done 👍
ask away
So my radio is no longer talking to the quad, in BF the input sticks no longer change anything and the reciever led is flashing, not solid like it was before
I changed external RF in the model to.. CRSF? Is this right?
what radio & module have you got again?
is it TX16S with internal ELRS or external (stuck in the back of it)?
TX16s and the module is ELRS, do you need the specific model?
aye yes, build in a little box, stuck to the back
on your radio, the expresslrs tool, just the top of it
Rapid, wifi mode
well, there's your answer then xD
if you leave it disconnected from the radio for 1 minute after powerup, it will go into wifi mode
just repower the receiver
Ahh
okay sweet, I have a solid LED now
but no response on BF when I flick switches, touch the sticks etc
I have nothing in the inputs/ mixes tab on my roma model
on the radio
doesn!t it ask you during model creation?
honestly I always avoided that by copying xD
I have the blank, personal, soarETX and WIZARD options
wzard?
looks like soal is for fixed wings, wizard uses lua to make models and personal I guess is if Ive saved any previously?
I usually recommend making themost basic pllane model
So should I start with one of the Soar models?
use plane because multirotor usually have some bullshit in them by default
you want no mixing, just one channel per everything
thats fine
roll, ch1?
yep
=AETR
so I need to reorder them?
you just need to tell BF that they're in this order
in Receiver tab, channel map
RETA1234
or you can reorder them
your pick
Okay, updated to RETA1234 - and saved in bf
I changed external RF to CRSF, I can now see the control inputs in BF
Aux 1, ( SF ) goes from 1000 to 2000 when switched
On mixes, on the radio?
since you already see it in BF, the radio part is done
that looks good to me
great!
realistically
you should be able to disconnect usb (and batttery if connected)
plug in battery
and arm it
you should set up the other modes before you fly
beeper, flip over after crash, angle (self-leveling) if you want it
yeah good idea, I will do that
so fire I do those in the radio, then they will appear in modes tab on bf?
they won't appear in modes tab, you set them up
Okay
like, the modes are already there. You're setting up the channel ranges which activate them.
I usually set up one 3pos for flight modes and another 3pos for "rescue" modes (flip over, beeper)
quick tip: don't put beeper on the middle position of a switch
middle is the default when radio is not connected
so it would beep on powerup
Ahh okay
So SE for the rescues and SG for modes
Not sure how to put turtle mode on the same channel
Oh okay
by assigning a 3pos to a channel, it will switch the channel between 3 values
1000, 1500, 2000
so you set the 1500 position to flip over and 2000 to beeper (in BF)
okay! I'll plug back the quad in and tackle that now
Changing the aux will change which switch the function is assigned to?
AUX3 in BF is the same as CH7 in radio Mixes
so if you assigned the switch to CH7
then you want to work with AUX3 in BF
you should havve it enabled permanently in BFC Configuration tab
otherwise, you should have it on a switch where it's on by default
you need it for the drone to fly correctly at low/zero throttle (falling)
okay , its on the same switch/aux as arm
which flying modes do I want? Ive forgotten what they all mean
acro is the default state of betaflight
angle mode is the stabilised one
horizon is the one that we hate
acro trainer is acro with max angle limits
okay so I won't bother with Horizon
just acro and angle 🙂
I don't see Acro in the list, would that mean it will be acro when not in Angle in that case?
acro is the default state
OK, in that case I think I'm set, is there anything else you can think of that I may need to do?
check failsafe
arm the quad, turn off the radio
make sure that the drone turns off
Okay
Is it possible to set a failsafe where the quad will go into an angle mode, with a certain amount of throttle so that it would safely decent if you lose signal?
oh yes the flying lawnmower of death
that either drops onto you or flies away depending on the air pressure that day
eh?
sorry maybe I misunderstood, not the failsafe option in 'modes'?
oh I see
failsafe is what happens when you lose signal
that's why I'm telling you to arm and turning off the radio
so that you simulate signal loss
Sorry I thought it was something I had to enable
np
yes! fail safe works
@rapid marsh you got your goggles?
in Betaflight, Video Transmitter tab
you should pre-configure stuff
band, channel, power
and then tune your goggles to the same band & chan
yuuuhh
idk how to deal with DJI
you're on your own with that
can you show your Ports tab pls?
just to check MSP
seems configured to me
Sweet 🙂
Hi all, I've just ran into a problem, while updating the dji goggles, and then the air unit. Going through that while rigmarole, I decided to put the props on and make sure it all still spins up,
I get the whole 'telemetry lost/ recovered' audio from my radio but I can no longer arm it, and when the quad is plugged into bf I see no control inputs in bf, what could be the reason for this? Btw I'm leaving for Norway tonight so please help me trouble shoot this as I want to take the drone desperately 😅
@rapid marsh hey, what's the receiver led doing?
@rapid marsh also -
https://discord.gg/expresslrs
The reciever is a solid amber
Okay I've checked again , was solid last night but now it is slow blink, waiting for commectuon from transmitter
External rf is set to crsf
The radio module has a solid red led
When connect to BF the reciever led is a solid amber
does the receiver LED react to the radio being on/off?
we keep missing each otehr lol
Yoo sorry ik at work atm, should be back about 4
kk
No it doesn't, but I do get the audio queues when the quad is on/off
make sure that you didn't enable Model Match in ELRS Tools on the radio
Ok model match of turned kff
Off*
was it already off?
which flash?
you can tag me if I'm not responding, I'm not watching here all the time
thankyou, slow flash atm
( not bound )
and the radio is on? 😐
what did you change in between then and now?
then being the last time it worked
Okay lets see.. I changed some of the aux's in BF
I added angle mode
And then I activated the air unit and the dji goggles
and attempted to bind them
none of that should affect the receiver and stuff..
does the receiver go into wifi mode?
No
its solid when I plug the quad into a usb
but flashes 2 times in 18 seconds when in a lipo
when you plug in a lipo, how many beeps do the motors make?
video maybe?
check if you have a short on 5V anywhere
RIP battery
in our hobby, we call this "fucked"
you might be able to recover it..
Oh shit
Well. I have 3 more
you've got 2 cells that are below 1V
idk what your charger allows. Some will let you use LiPo mode to fix this, some won't.
But the battery probably lost most of its lifespan
if not all of it
it's like at -100%
Dayum
So it would make sense that the issue I have now is down to a depleted battery?
Okay
they usually come at 3.7-3.9V/cell
I just started charging one, is it safe to stop it already?
yeah
Okay so I have many more beeps on battery now
A solid light
"Telem recovered"
But cannot arm
Yes... But when I turn the radio on it always gives me a throttle warning
which side of the radio have you got the throttle on?
and is it set to Mode 2 in Radio Setup?
I will check, lemme grab that sc real quick
Mode 1/3 = throttle right
Mode 2/4 = throttle left
wat the heck
in radip setup the mode = 1
why are all of the channels maxed out xD
change it to 2
if you have throttle on the left, it should be 2
OK
can you show me the inputs and mixes on your radio?
what weirds me out is the fact that if the mode is wrong, the channel mapping should be too..
:/
does the channel mapping break if you change it to mode 2?
uhh sorry, my brain.. channel mapping?
in the mixes?
the screenshots were sent after I changed to mode 2
ok
your radio sends numbered channels
CH1-CHx
Betaflight needs to know which channel is which input
that's what channel mapping is
If the radio puts CH1-4 = RETA, then BF needs to know that it's in fact RETA
that's whta channel mapping is
anyway
Oh okay
I'm asking you to check in BF
if the correct channels still move
when you move a corresponding stick
the heck
right now, the model of the drone in BF is spinning like mad, when I turn the radip off, it stopps
I do remember taking the module out of the TX16s, just unpluggled it, I replaced it almost immidiately, could that have done something?
did you unplug it while powered?
well, if the ELRS tool works, then that shouldn't have done anything really
No
hmmmmmmmmmmm
okay. Create a new model on the radio
plane template
most basic one
Ok
send pics if you need guiding
show me the inputs and mixes
okay, go into Model Setup,
set Internal RF to OFF
External RF to CRSF
and see if that changes how it behaves in BF
no change, does it need a power cycle?
try to power cycle everything
then, in Betaflight Configurator, go to CLI tab
send this command: diff all
then press Save to file
and post the file here
I may have to send you off to ELRS discord soon tho 😦
btw did you try to recalibrate sticks on your radio?
in hardware, radio settings - I have internal Rf - multi, External RF - normal?
that's normal I think
Not as far as I know
can you show the Hardware page?
yeah
I'm thinking like, did your radio SD card die or something? 😄
aye
ADC Filter should be off
but that's not the issue
the Inputs calibration works as expected?
the sd card is readable on my pc
I didn't really have much of an expection tbh I've never done it before
I followed a tutorial for the calibration
when it tells you to move the sticks in a certain way, do it in the physical sense
disregard what you see on the screen
oh this is weird
the little circles showing where the stick position is are in the corners
I can't bring them back
well, that's the problem then
Do whatever you want man
At this stage I'd sell a kidney to get this working
my radio is your radio 😅
I'm wondering how you broke it tbh xD
I really wish I knew
@rapid marsh can you look for Factory Reset on the radio?
yes
apparently I have to delete the radio and settings folders ont he SD card
Should I proceed?
in the same thread, the guy said he did exactly that and now his tx16s is 'trippin'
Okay
sorry, I've never had to reformat an SD card before, I assumed I could just right click and click reformat, how do I do it?
SD card reader
and you're on windows?
yes
shit, yeah my bad I missed it
FAT32, Default allocation size, quick format ON
ok, done it twice now as first time was only FAT
Now it's completely empty, does it need to go back into the radip to load all of the files?
no, keep it in the reader
the radio's USB is super slow
download this, extract it onto your PC first, then copy the contents onto the SD
don't extract directly onto the SD, that will be dog slow
elrsv3.lua into Scripts/Tools
show the root directory of the SD card too pls
(root directory = X:\ )
before copying onto SD?
after?
after
asking cause here you're in documents, not on the SD
ahh shit im dumb
^
Its loaded into the calibration page, same weird thing with the circles In the corners
you wouldn't have happened to like.. .drop the radio?
No not to my knowledge
I broke a switch once, ever since replacing that I've been very careful with it
I'm so confused ffs
o
you've been inside of the radio before?
then you should check the stick connectors
that's cause External RF is off
are you already taking it apart?
I've just started
just wanted to ask - the inputs were always permanently stuck in the top right, even when you moved them to the bottom left?
Yes, no matter what I moved, they are static in the corners
and a dumb question
did you press Enter (click the scroll wheel I guess) to start the calibration?
Yes
okay, we'll retry after checking HW
Waiiitt
So, when the radio booted, it booted into that calibration mode
I hit enter as normal, nothing
So I entered through the stages fiddling with switches and sticks as i went
make a video of the calib 😄
I went into hardware to try again, sticks in the corner
I moved them, and this time they bounced back
okay, do the calibration properly now 😄
do what the radio asks you to do physically
it's asking oyu to center the sticks
so center them physically
this means - just center the throttle
the rest self-centers
then press OK
to get to the next step
Okay but should the circle go down to the bottom when I move the stick to the bottom ?
The pots are these..
And the front facing knobs up top ?
Okay, that's done
Okay, changed external rf to cfrs
I'm now seeing movement in bf
yess
Pitch roll and yawn at 1500 as it should
now read vitroids guide on setting up the mixes again
So was all that due to me fuxking up a calibration ?
idk
it looked to me like a corrupt radio.yml file or something
didnt wanna risk shit
Okay
I don't suppose you pinned that guide?
You told him to put it somewhere right?
In OpenTX, the default multirotor model only has the four main control channels mixed in; throttle, yaw, pitch, and roll. To get the radio to send the switch values as well, they need to be mixed in:
Go into the model setup, and page all the way to the mixers page
Scroll to the empty channel 5, and long press enter to make a new mix
You can o...
thankyou
afk, tag me if you need
Okay, I've set those, reciever tab and modes tab are showing when I flick switches etc
I took out usb, plugged in a batt, and tried to arm but It did not arm, I am missing something
check throttle minimum
check arm switch is on AUX1 and ON at 2000~
in BF Setup tab, on right side, you can see arming disable flags
try to arm and see what it tells you
after unplugging usb you should replug power as well
or it won't arm
it thinks the throttle is still not idle
how low does your throttle go in BF?
OK I copied the order it says in the radio, but I still had to swap Throttle and Pitch in BF
it seems fine now
in BF receiver tab, the stick ranges are 1000 to 2000
BF by default uses 1050 to 1900 as its input range
but it requires the stick to be able to go below 1050 and above 1900 (to detect stick min and stick max)
below stick min is necessary for arming
what is MSP? In arming disable flags
throttle is going below 1000 but still giving me a throttle not idle warning when turning on radio
that is usually because of the MOde being wrong
odd
make a backup of your radio's SD card lol
when you try to arm or when you plug battery in?
arm
keep in mind that with configurator connected, or after having configurator connected, it will not arm until you power cycle it
if I try to arm with throttle on, it plays some strnage sequence of beeps
Right so its arming now

Wouldnt have been able to get anywhere near this stage without your help GGManiack. I'm sure it wasnt always easy trying to help me as I'm about as nooby as you can get. So thankyou. I really appreciate everything you've done to help me. Yoire a credit to this community!
Hopefully, I'll have some cool videos to share with you all this time next week
