Holystone Quadcopter will not pair. No wifi signal

My Holystone Quad Copter (FI83W) does not send a wifi signal to my phone. I cannot pair the remote with the copter, either with the phone or the remote controller. It never connects and the "FPV***" wifi does not show on my phone. My son has not used this quad in some time (4 months) but it was running fine when we put it away. We have two batteries and charged one fully (the light on the charger went off) nut the other one will not charge for some reason. It makes me wonder if there isn't something wrong with the charger. We went step by step through the manual to make it pair but with no signal that will never happen so . . .??? Can someone help?

You need to get a cheap multimeter to be able to check the battery voltage right after charging.

Yep, or at the very least one of those $2 battery monitor/buzzer gadgets.
I strongly recommend that no one should ever fly without one of those anyway, unless you've got telemetry.
 
Leaving cheap Lipo's @ full capacity for months can ruin em, it may charge up but loses it very quickly. Or the function of the make up only let's it charge a certain portion or cell. Yes a multimeter would be handy. Toy quads batteries don't have a way to monitor the juice like 2s3s4s:rolleyes: batteries balance lead.
Hell even graphene do this, I got a few 4S that are running on 3 cells. The last one reads 3.2v when all others @ 4.20

Those little monitor/buzzer gadgets will read toy grade single cells and usually go all the way up to eight cell packs too, they are also very accurate.
While I agree a multimeter is a worthwhile investment, the only function typically used would be the DC voltage selection and you can get
a whole handful of those bat buzzers for the price of a multimeter. ;)

You keep charging and using a 4S with a bad cell and you're just asking for trouble. :eek:
I'd just remove the bad cell completely and use the pack as a 3S ... btw, it's better to run a good 3S than a 4s with a bad cell :D

Could be any number of things wrong in this scenario.
Could be a power problem as discussed, or the quad's tx could be dead, or could even be an app compatibility problem.

Download any free general purpose WiFi checker app onto your phone and look at what it's "seeing" before and after you turn on the quad.
If the quad IS sending out a signal then you'll see it pop up on the app and should start looking at the controller app as the problem, like Moz said you might just need to update it ... A general checker app is also good because it will also show ANY other signals (not just yours) and yours could also just possibly
be getting swamped by some other nearby overlapping signal (like an internet router for instance) :cool:
 
The only use for a multimeter is dc voltage. I think the continuity test is more valuable. For finding shorts.
Let's face it if your putting a bat alarm on a 1 cell, then it's going to weigh the same as the battery nearly. Depending on which bird you have. Me personally don't use one. I can tell when it's about to go.
You get a loss of power not totally but enough to bring it down safely. I only stay up for 5min anyway, I don't like to run em empty 3.8-3.9v per cell. I only us turnigy batteries & graphene. Got a couple of tattu for best.

Bullshit. These work fine.

Never even seen a multimeter for $4 before ... smh... all I can say about THAT is you probably get what you pay for.
These bat monitors are dedicated to doing one thing, measuring DC voltage to one hundredth of a volt and they do it well.
I've checked them against my NIST certified $500 meters and so far they're always dead nuts on the money; not bad for about $2 each.
Having them ride along airborn with a built in adjustable low voltage alarm is also an extra bonus. Not to mention they keep beeping even
after the cells are too low to fly with and, as such, also act as a fine "lost model finder", and you can't do that with any multimeter.
The point being, they do exactly what you'd (primarily) be buying a multimeter for, for much less AND have their other uses too. :D

Single cells usually weigh close to thirty grams and these monitors weigh less than ten grams. Well worth the protection factor if you ask me. ;)
 
10g is 10g. Esc's do me fine. :cool:
Maybe on a 210 or bigger.
If you're shaving the grams off for a 3inch racer obviously not. I fly acro & have lost about 6 of these, getting caught on branches or fences. I do carry one in my bag. When I go out I like to spend the day, most times. So I can get out with about 30 4S pak's & about 10 3S for my goggles and GS & now seven 3S 350+450mah.
Only flying my 130 @ the moment in this weather. But springtime, nearly 40 batteries for a day of it. (illegal flying)o_O
150mw:confused: over limit, no spotter,:rolleyes: un-registerd. 5 quads to choose from. :)
So i could lose em all day long.
Like putting my wallet on top of my car. It's that light$$ with no velcro it will fall off.

True enough, for hobby grade quads, but you can't sing with toy ESCs.
Also doing that requires enough voltage (that hopefully is still available) to pulse the motors hard enough to generate that tone (btw it's the motors, not the ESC that make the noise) AND it's not nearly as loud as those bat alarms, but point taken, you CAN get away with using ESC/Motor Beacon for lost models.
