Naza M Lite to M V2 Upgrade Project (Was: This is interesting, I may try it)

[Hands0n]

Does any one else find the the motors speed not increase when taking off with 0-50% throttle input

Yes, that is perfectly normal these days. DJI changed the way Naza lifts off - once you get just over 50% it will lift off under its own control.

Hi All.
Was wondering if any of you lot who have done the v2 firmware upgrade are experiencing an issue I am.
On startup, I am getting short bursts of flashing red led.
This usually continues for around 2 mins. The radio signal is fine as the light changes to constant flashing red if I flick the failsafe switch for example.
I thought it was a mid stick error and found my old turnigy 9xr was a bit sloppy around mid stick so I bought a new taranis. But alas the problem is still here.
It';s a new generation of naza lite v1.1. I really don';t want to go back to the original lite firmware as when it';s up the difference is great.
I did find an old post on another forum describing the same thing on a naza v1. It was described as a warm up time. This was fixed with the v2 apparently.
I have tried restoring back to lite and then refreshing with no joy.
Any suggestions guys?
Cheers
Rob.

is it 4 quick flashes? mine does this but im sure its just the warm up procedure

[robshaw]

Yes it is mate. Didn';t do it when it was on lite firmware tho. And v2 doesn';t have a warm up time...?!

Exact same thing here

[Hands0n]

Here';s the DJI information about the various LED sequences.  Does what you see match any of these?

Ahh. Glad to see I';m not on my own anymore.

The only one it could be is the 4 orange flashes. ';Warm Up'; Its difficult to tell between red and orange as the LED is soo bright. But as there is nothing posted for 4 red flashes I';m guessing it must be orange. Takes minimum 2 mins but more often more like 3+ minutes to stop.

Not really its orange flashes around one per second for ~ 2mins It not loss of tx signal. After two mins then get the usual green sat lock flashes and everything is fine. After changing battery for a new flight the orange flashes go for around 15 seconds.

[flybywire]

Those of you who owned the original Naza M (or v1 as it is sometimes referred to) will recall how ';a certain'; firmware update changed it';s behavior significantly.  It was released the same time as the V2 was introduced, and added a more stable take off algorithm, and semi automated takeoff as well as a few minor improvements, support for OSD etc.
Now, I had both versions, so I know the differences between them.  I found, after I had updated my V1 to the V2 firmware, that although they now appeared the same (in terms of the assistant & functions etc) and in terms of flight characteristics, when it came to booting them up for flight, that';s where the differences lay.
I';ve only ever had 1 glitch in my history of DJI ownership, which was with the V1, never repeated in V2.  V2 feels more robust, and ';locked in'; than v1.
DJI introduced a warm up period (to counter reports of flyaway';s due to incorrect GPS home point) So far, so good!  On my V1, this warm up could take up to 2-3 mins (i never actually timed it so it';s anecdotal rather than scientific) whereas my V2 would get a lock (green flashing LED) pretty much straight away.  This behavior was constant, and made little difference with location.  I often fired up both multi';s simultaneously, to observe the difference, and always got same result.

So, my conclusion (which involves a little conspiracy theory on the part of DJI) is that judging by what I have read by you folk here, is that the ';Lite'; is basically a re-badged V1, at least in terms of its behavior.  I can';t prove this, but in all practical senses, this is how things appear to be.

i.e When you jailbreak a LIte to V2 firmware, you get the equivalent of Naza M (v1), not V2.

[robshaw]

I think your right flyby. I did read about the v1 warm up time and it seems very consistent with what I';m experiencing.

[DarkButterfly]

I don';t mind the warm up delay, it allows me to conduct a preflight check whilst it';s warming up

[flybywire]

Yes, that';s fine, but the implication is that the jailbreak will give you a V2 for price of a Lite, which I believe, is a tad misleading, to say the least.  Moral of the story?  if you want v2 performance and reliability, buy a v2!  Plus, you get all the canbus connectivity as well, which TBH, is 80% of the reason you buy one in the first place!

[robshaw]

You get can bus with lite upgrade too (once you buy the v2 PMU...)

What bothers me is that some people appear to be having no problem with the upgrade and others, like me, are. Which suggests varying hardware in the lite units. My model is the very latest v1.1. Which has the v2 style led module. So of all the models I would expect to work, it would be that one.

Anyway, Hey ho. Was worth a try. No massive loss. Back to lite.

Starting from cold, does anyone actually not have to wait 2 - 3 mins until  the orange  warm up LED stops flashing?

[robshaw]

Well Ive posted this issue some time ago and it seems that nobody else has the problem.  Your the first person Ive come across that is experiencing it!?!

I have to wait, but it seems to depend on how cold it is outside, plugging in the naza at room temperature, it initialises quicker, but it does give me time to check other things before flying

[flybywire]

Yes, of course, but that';s nearly 50 notes, add that to your £120 for the lite, a few quid off of a full v2!

The jailbreak hack is just that, a hack.  Don';t expect miracles.

I dont think its a problem. I think its just how it is. Mine does it as mentiined before and a  few others

Room temperature 2 mins   2 Centigrade 4 mins

[realpastaman]

Put quadcopter in the cold outside ~2C for 1 hour - brought inside and did advanced calibration whilst still cold. After sometime when everything has warmed up to room temperature again I tested start up time again and its now 20 seconds instead of 2 mins - Result! :) repeated this many times again after 1 hour and its still 20 seconds!

I have a V1 upgraded to a V2. Like others I have to wait up to a few minutes for the four orange/red flashes to go away. Nothing to worry about that I can see, it for just fine on 4.02 (I think) firmware.

Did two test flights today. Flies great! and now has really fast start up time. I think long start up time is caused when IMU advanced calibration is performed when the IMU is too hot. ie reduce the temperature a little before performing IMU advanced calibration.

Also reduced the sat lock time significantly by using one of these. At ~ $10 its great and well engineered

7C Ambient temperature today - Warm up time and full sat lock ~ 1 minute :)

[robshaw]

Cool. I';m gonna try that imu calibration at lower temp mate. Thanks. Think I';m gonna also order the high gain antenna too. I like a bit of a tinker.

[robshaw]

Just ran advanced calibration whilst cold. Unplugged and plugged back in and it went straight to gps search, no warm up flashes. It';s now switched off and ';cooling down'; for another switch on. Fingers crossed.

Hmm. Still needed a warm up. Was shorter tho. Will test more thoroughly at the weekend and feedback.

How short?

[blankstare]

I tried this, the firmware upgrade was fine apparently but the motors would not start. The gps on the naza lite plugs into the mcu whereas on the v2 it plugs into the power unit. I had to "upgrade" back to naza lite firmware to get the quad to fly.

[Matt101]

I have a Lite here doing nothing. I was going to do the upgrade and have a mini iOSD to put on. So I know I need the PMU V2 for that alone but can I change the LED to the V2 version too doing away with all the associated wiring? It';s only £8 after all and looks so much neater.



Cheers

[robshaw]

Yes you can.
