Can You Upload Data From Dexcom Receiver Through Usb Cable?
The USB cable that I used to know
One old Motorola cable used to work and now it doesn't, 1 new cable works neat. I new cablevision says information technology'southward charging but it'southward flaky and doesn't turbo charge. CodingJoe Joseph Nielsen: Why do bad things happen to good phone chargers? Permit'south swoop in and see what nosotros can notice. The USB cable that I used to know is the same. It's not easy to have a close-upwards of the cables with your hands full power.
We all end up with the same question: why do bad things happen to skillful phone chargers. This is my problem: one old cable used to work and now it doesn't, one new cable works nifty, ane new cable says it's charging but it's flaky and doesn't turbo charge. Let's dive in and see what we can discover.
On the surface, these three cables look the same. (This is a cue for me to bust out my handy dandy Celestron microscope.)
Only first, how do they work?
A quick Google Prototype search for "micro USB schematic" returns this image from this website.
I was embarassed afterwards I learned this information. I used to think the outer beat had something to do with the electricity after watching some artificial YouTube videos where people endeavour to fix their cables with needle nose pliers. It all has to do with the border pins on the within.
My expert old Motorola cablevision
I've got a Moto 10 Pure/Mode. The cable has recently lost its grip and I have to hold it in in society for my phone to stay charging — (my third replacement).
Here's the close upwardly of the one-time Motorola.
The Imkey cable (aka this thing looks clever with springs on the ends and it'due south covered by Amazon Prime number)
When the Motorola cablevision became loose I thought okay, I'll gild another cable online and to make certain it doesn't get faulty over again — and because I'one thousand and then clever — I'll guild this fancy cable with springs on the end. Except when I go the cablevision my phone constantly changes its listen most whether or not information technology'due south charging. Information technology likewise doesn't do "Turbo Charging" mode. Then yeah… I now have a clever phone cable that doesn't charge. (Only hey, shipping was complimentary.)
Here's the close up.
My married woman's new Samsung Galaxy 7 USB cable
While I may be prone to remember I got unlucky with the Imkey cable, unfortunately the Imkey cablevision situation is true for every other cable in my business firm. I was thinking there must be something near either the turbo charger plug or the turbo charging cablevision. And then I tried out the USB cable my married woman got with her Samsung Galaxy 7. Information technology worked great. Non flaky. Not loose.
Here's the close up.
What'southward the difference?
At first glance, the reason why my sometime Motorola USB cablevision slips right out is immediately apparent. It has no fangs!
(I had thought peradventure information technology was filled with dust. I saw a YouTube video that talked near that. Merely there was nothing in there subsequently I done the cable out with an insulin syringe and rubbing alcohol, followed by lots of Nintendo blows to dry out it out.)
The fangs haven't broken off of the cablevision. They've just lost their spring. I needed to bend them dorsum out.
I searched around for some different tools: blood sugar lancet, sowing needle, push pin, needle olfactory organ pliers. In the end, the push button pin worked all-time at jimmying the fang back into place.
It should go without saying: unplug any charger cables earlier y'all mess with stuff. This is non a "how-to set" article only a "allow'south mess with stuff and hopefully non kill myself or start a fire but if it happens that'll be absurd too" article.
So I bent dorsum the fangs on the USB charging cable and information technology worked great. Fits snug. No longer has that "is information technology really plugged in all the fashion" feeling.
Bank check out this flick to see the contrary end of where the fangs get.
After reviewing this close-up of the female micro USB, I idea maybe I've besides bent the impressions on the inside so that the fangs accept to be bigger in guild for the cable to work. It reminded me of how I stock-still my old record thespian from Junior Loftier — the needle wouldn't work until after I taped three pennies on to it.
The Imkey isn't exactly the same as the Samsung USB cable
Using sophisticated "count the pixels on the screen" measurements, I calculated that the Samsung cablevision's fangs were 26% the height of the chief cable male person body. The Imkey cable's fangs were but 24% the height of the main cablevision male body. Size matters.
So I jimmied the Imkey fangs out a little more. Sure enough it snapped to a lot better, however information technology notwithstanding didn't recognize 'Turbo Charging" mode. That's when I too noticed when looking downwards from the top, that the Imkey'due south shaft was longer than that on the Samsung cable. Also, the Imkey'south pins appear to be slightly tighter. (17% on the Imkey; 21% on the Samsung and Motorola.)
So it'due south still across me why the damn Imkey new cable won't work as skillful equally my newly fixed Motorola cable or the new Samsung cable. My best judge is that the pins don't line up equally good equally the other ii cables. I too don't know if the cable simply doesn't support the required ampere for Turbo Charging.
In decision, examination what you think you lot know and await closer. I promise these close up pictures help any troubleshooting you're doing with your own cables.
Hither are links to the cables I worked with: Motorola, Samsung and the Imkey. I took pictures with this Microscope.
