Bluetooth connectivity of Reach around motor vehicle

[davehofer1993 (David Hofer)]

mod edit: splintered off from this topic regarding bluetooth connectivity around motor vehicles:

RS2 Bluetooth paired not connecting

We’re having an issue with the RS2 connecting to our devices via Bluetooth. It will pair but not connect. We’ve tried a Windows 10 tablet, Android and iPhone. We had no real issues connecting to a reach RS+. But given how the RS+ had issues maintaining connecting perhaps it’s a Reach Bluetooth issue? Either way, so far I can only pair and not stay connected via Bluetooth any device and the RS2.

It sure works here with bluetooth

[bide]

Sure! You have your RS+ elevated plus a clear line of sight into the back window glass to the tablet

How good would it be if you put your tablet on the cab roof in front of the air conditioner? Maybe it would work, but maybe not so great.

This is the the kind of placment difference that I think we’re dealing with.

edit: upon closer inspection I don’t see air conditioning - maybe just a storage box or escape hatch.

[davehofer1993 (David Hofer)]

Actually that is AC.

@bide

Well, with the metal rack under the computer and the metal handlebars and maybe/maybe not the metal spooling rig on the back of the ATV (but certainly the metal frame. Why not just stick a good (or beefed up bluetooth unit out the back of the quad and route a USB extension cable up to the front mounted computer?

This way the antennas can all see each other directly without any metal inbetween. I think that is the best chance for success.

The other thing is the ATV ignition system (probably located somewhere between your knees). Even though it doesn’t seem to affect at idle, it might be that bluetooth can find a happy channel without interference when the the ATV is idling, but when you are driving and the throttle is moving up and down, maybe the interference is more broad spectrum and none of the bluetooth channels are free of interference.

When you were mentioning this I just thought about all the metal we have here

[bide]

Indeed, that is a lot of metal

…and I’m glad to know you’re keeping cool in there. I should have known as I thought I caught a glimpse of a bag of natchos in the cab there. If there was no A/C then I think it would have been ‘cool ranch’ instead!

@bide

Internal combustion engine with electronic ignition

• are you running a resistor-type spark plug? (for less electriclal noise)
• does the dropout behaviour change with engine on/off?

It may be the electronic ignition which amplifies the voltage for spark to the spark plugs? Maybe electromagnetic interference causing the bluetooth drop? Maybe it just needs properly shielded or really more so grounded?

Maybe see if Tesla makes ATVs yet and try one of those? Yes, I think they do:

Yeah, I dont know what that guys thinking . you run out of water eating these

[bide]

@davehofer1993

Yeah, I dont know what that guys thinking

Apparently a couple of days ago Elon was seen about 20 min from here at a little cafe off the beaten track. (source: local gossip)

[timd1971]

I think you need to use a Zamboni.

[bide]

because it is powered by an aircooled VW horizontally-opposed 4 cylinder with point-type ignition?

[timd1971]

YES!!!

[timd1971]

@bide

natchos

Gnatchos

@intenna is like WTF happened to my thread?

[bide]

I think you are right and the EM38 would fit nicely inside the conditioner housing at back. It just needs to be chopped and narrow-tracked to fit the ATV profile.

the poor OP didn’t know what he signed up for

edit: I think I better split this post now since I am a party to this off-topic escapade

And to think it all started with this:

[michaelL (Michael Lambert)]

What elevation mask are you running?

[davehofer1993 (David Hofer)]

15 degress

[michaelL (Michael Lambert)]

That should be plenty good. Have you tried to PPK test some data to see what the scraper is actually being provided. We typically run 20deg on our equipment with Topcon as long as we get at least 8 good satellites afterwards. It has improved accuracy a little, but more importantly the machines track faster.

What software are you using for guidance and reporting?

[timd1971]

FieldGenius

[michaelL (Michael Lambert)]

Gotcha. Missed that from the previous thread. Staking of surfaces would be a great edition to most of the survey softwares we have access to. Using an indicate system is much more helpful and safe when it has some type of “light-bar” readout instead of watching numbers. I need to do some perusing on using Emlid on machines as we have several pieces of equipment that would benefit from indication, but they don’t justify a Topcon system.

[timd1971]

Yeah, and might as well use the RS2 since making serious money and don’t have to worry about trees etc. Even though mostly in clear sky view, there will always be that day you wished you had a multi-freq RS2. ; )

I REALLY hope Emlid is using all the other survey programs etc as good reference to build their own specialized ReachView Survey app… which includes localizing, coordinate systems, COGO, RTS, and yes machine indicating, among many other professional features.

And yes, even as much as I HATE subscription services, I’d PAY for this from Emlid… but looks like Microsurvey for ANDROID (or current Windows) may still be the go-to until then.
