Is the “automatic” update working on iOS?
Or is there something special to force an update?
Automatic update is working in iOS. But manual update is still an option if you want it, you can force that to happen by rebooting the meter and connecting to it in the first 5 seconds (when it is giving long slow flashes).
-25dB to -60dB… ; and at times, while being used, the Meter view goes back to the scan view (maybe the reason is the low signal, but, again, they’re so close…).
Is that a “normal” behavior?
Those signal strengths look good, I can usually maintain a connection all the way down to -75dBm. Falling back to scan view if the meter loses connection is normal behavior, but I don’t usually see that happen at -60dBm. Quick test – does the disconnect happen if you leave the meter sitting in DC mode, or only when you switch to AC? This is related to some other user reports for an iOS bugfix in the pipeline.
Can you kindly mention what MAX would be, roughly?
MAX frequency will have no delay between subsequent readings, so the resulting frequency depends on the sampling settings. For example, if your sample settings are 32 samples at 125 Hz, you’ll get a logging frequency of roughly (125/32) = 3.9Hz
– tapping the screen starts the sampling, which lasts about 1 second (for 0.25 second of data, 2 Ch). Does the sampling starts exactly (say within 0.1″) when the “tapping” occurs or is there a delay?
Sampling will start as soon as the meter receives the tap notification, which should be between 0.01 and 0.05s (depends on the phone).
– the sampling represents only 0.25 second of data. At least 3″ would be needed. The Trend mode would be ideal in this case but it seems its max resolution lies around 0.3~0.5 second. Can the Trend mode samples more quickly than that, or could the Burst mode last (e.g.) 3″?
Hmm – I’m not sure exactly what you’re trying to measure so I will try to give answers to make both burst and trend work for you: Burst mode captures a complete frame of data from the meter and transfers it to the phone at whatever sample rate was set in the main “meter” screen. So if you set the meter to “256 samples, 125Hz”, that should give you a 2 second frame of data.
Trend mode receives processed samples (not raw buffers) and plots them as they are received. You can make it update faster by adjusting the sampling parameters in the main meter screen – for example changing from 125Hz, 32samples to 125Hz, 16samples should increase the density of points in trend mode.
Also I have a large update to this feature in the works, I hope to release it in the next week or so.
Documentation (Thanks Google)
Most of it is here, but I acknowledge it’s quite out of date since we’ve been continually releasing updates and detailing the changes in the blog.
But even I search google with “PHRASE site:moosh.im” quite often. We just shot a new product video and will be making some website changes shortly as well.
I hope this helps, please let me know if you have other questions. Best
