It gives you the option to pair a "weather meter". Does anyone know if using a WeatherFlow weather meter hooked into your aux jack will link up and self populate into the fields or will you manually have to input the data?

I have a weather Flow somewhere — I’ll report back..
Btw weather never really changes fast enough to really worry about tethering. Wind, well.... I’m not a fan of the output anyway..
Edited to Add the $84 flowmeter/weather station w/bluetooth works.
I just went to look for my AB Kestrel 5700 and I can’t find it to confirm. It has been many months since (a few days after the release), I even used it. Sorry I can’t confirm the Kestrel.

I have the weathermeter and as far as I know the device only communicates via Bluetooth. The aux jax is just something to stick it into to hold it up. There is nothing in the manual showing any technical specs regarding communication via the aux.
I'll try to connect it via bluetooth and see if the 4dof app will populate from it and post back.

I've been successful with 4DOF pulling atmo:
WF via bluetooth
K5700 Elite via bluetooth (must connect up Kestrel Ballistics app first IME)
I have not been able to pull atmo from a non BT WF into 4DOF. I don't believe that functionality exists within the 4DOF app to pull atmo into 4DOF from the 1.5mm audio jack.
The integration of these different devices, OSs, platforms, and apps will leave some unchecked squares for you to find out what ends up working for your specific setup, no matter what the mfgs claims are in my experience.

Ya, I have a iPhone 8 no jack anyway. I think they have both a lanyard and aux adapter solely for convenience, not connecting
Yeah each time I have tried to link up the kestrel 5700- it “blocks” the firing solution and I have to input manually ie it will say my elevation is o no matter the distance. I’m sure there’s a fix on the way- but I just type it in
mine always says the elevation is 0 too. But i think as long as the meter populates the rest of the fields it is able to calculate the DA. I could be wrong. I left it at 0 at the match last weekend and my solutions were right on... I was afraid to mess with it lol.
You can toggle the elevation "off" and then manually input it.
4 DOF wants station pressure...so as long as that's input and not local corrected baro pressure...than the MSL altitude won't effect your calcs much.
But if you toggle it off, just input the msl altitude (like off a contour line from a 1:50k topo map) and you should be gtg

Not weather station related but does 4DOF have some way to adjust for scopes that are out of calibration (if 1.0 mils were actually 1.1 or .9)?
It is probably a little early to say this as I haven't done as much testing as I'd like, but the 4DOF app paired with a Weatherflow or my 5700 Elite is more accurate to 1 mile than my 5700 Elite with AB. This is the 110 SMK using the AB CDM and the 4DOF "form factor". AB seems to be off a bit after about 1150 yards, I've always had to use 2 different setups in the kestrel depending on how far I'm shooting. 4DOF seems to be true to a mile. I hope to do a lot more testing this weekend. I'll report back anything interesting.
I have seen nearly the exact same results.
The Kestrel stays within .1 MOA until 1135ish then starts to flatten out. I am having to run my MV 19 fps faster on the kestrel than what my actual mv is to keep it true to 1135yd.
My thoughts were for any LR varmint shot I can use the kestrel and for anything longer I need to break out the Hornady app.
I actually have had enough success with 4dof that I used it to "true" the kestrel.
Yeah I called them about the app missing a scope correction factor & multi-wind but the guy didn't seem very knowledgeable or interested in my input.
So far it does provide accurate solutions even though the environmental inputs are not really user friendly.

There is a rapidly developing & rigourous interest in Hornday's 4DOF app among myself and other LR shooting enthusiasts, across multiple shooting disciplines. Many shooters are finding the solutions generated by this app to be the most accurate, amoung many of the solvers available, especially at LR/ELR distances. Inclusion of the following feature sets and/or improvements would further market depth and breadth that 4DOF has captured thus far.
1. Ability to input multiple wind bands (and being able to define those bands)
2. Optic Correction Factor (so as to account for optical tracking errors withing the optic). Ideally this would have a % value that could be applied within the rifle profile.
3. Ballistic Doopler Library Data for the following projectiles:
Nosler 6.5mm 140 RDF or ???
Thank you for the consideration of my recommended improvements.
