Aug 26 10:19:10 <kremlin> zmatt: ill fix that
Aug 26 20:34:15 <David66> Hi All,
Aug 26 20:35:53 <David66> I have a question related to hcitool lescan. It seems only scan at every 30s or more. The bluetooth beacon sends Adverstisements in less than 1s.
Aug 26 20:54:38 <zmatt> isn't hcitool deprecated?  (replaced by bluetoothctl)
Aug 27 00:28:25 <set_> BBBlue!
Aug 27 01:45:38 <set_> If I was to put a couple or more of the 7.4v, 2S LiPo batteries in series for extra oomph and longer flight times, would this affect the BBBlue in a negative way?
Aug 27 01:45:38 <set_> ...
Aug 27 01:46:19 <set_> I do not want to oust my BBBlue in flight but staying up longer is "better."
Aug 27 01:47:32 <set_> What exact equation is there to test for the power of the LiPo in series w/ respect to amps?
Aug 27 01:51:29 <set_> Sorry. Do not worry. I am on this idea.
Aug 27 01:51:35 <set_> Back to the charts.
Aug 27 01:55:50 <set_> Aw! My battery book is gone!
Aug 27 02:34:54 <zmatt> set_: trying packs together in series would double the voltage and is absolutely not allowed
Aug 27 02:40:46 <zmatt> tying them in parallel can be done, but requires being very careful, especially at the moment of tying them together
Aug 27 02:42:30 <set_> Oh.
Aug 27 02:42:35 <set_> Dang.
Aug 27 02:42:41 <set_> Okay.
Aug 27 02:45:07 <zmatt> it also needs well-matched batteries, and that may be difficult to determine
Aug 27 02:45:31 <set_> Yea. Parallel is the way to go. I do not need to double the volts.
Aug 27 02:45:45 <zmatt> well
Aug 27 02:46:08 <set_> I have all 7.4, 2S batteries of the same Ah.
Aug 27 02:46:18 <set_> Same mfg.
Aug 27 02:46:21 <zmatt> given how many potential issues there are and the fact that you can damage the batteries and/or set them on fire if you do anything wrong, I'd suggest not doing either
Aug 27 02:46:32 <set_> Okay.
Aug 27 02:46:41 <zmatt> if you want a higher-capacity battery, get a higher-capacity battery
Aug 27 02:46:55 <set_> No issue. My book on batteries is gone now. I have no clue as to what to do now.
Aug 27 02:47:04 <set_> Okay about the higher capacity battery.
Aug 27 02:48:11 <zmatt> a higher capacity battery pack may simply be multiple batteries in parallel internally, however as an adafruit article point sout "The individual batteries are tested and sorted by machine so that each pack has matching batteries with the same capacity and internal resistance. Individuals do not have this equipment, which is why you should not try to make your own packs."
Aug 27 02:48:35 <set_> Okay.
Aug 27 02:48:44 <set_> Yea. Batteries can be dangerous.
Aug 27 02:48:46 <set_> I know!
Aug 27 02:48:55 <set_> "trial and error."
Aug 27 02:49:28 <set_> bzzt, bzzt.
Aug 27 02:49:54 <set_> @zmatt: I got arducopter to work finally. It was b/c of the binding process of the rx and transmitter.
Aug 27 02:49:57 <set_> Ha, right.
Aug 27 02:50:14 <set_> I finally got connected to Mission Planner too.
Aug 27 02:50:42 <set_> Yea boy!
Aug 27 02:50:59 <zmatt> yes I saw
Aug 27 02:51:12 <set_> Should I make a thing/post on it?
Aug 27 02:51:41 <set_> If other people are still skeptical, I can direct them in the correct direction!
Aug 27 02:51:57 <set_> Two years and a silly binding process. Sheesh.
Aug 27 02:59:01 <set_> @zmatt: Earlier when I typed the questions, I was basically trying to account for time of flight w/ my specific motors, powering the rx, and having power to the board (BBBlue).
Aug 27 02:59:02 <set_> ...
Aug 27 02:59:33 <set_> But...those motors have no datasheets. I have no clue as to how to start my findings.
