Good morning! I have been trying to make offline looping work with Dexcom G4 plugged in to an explorer board v.1.2 2017, and no good. The cable (2 of them) are usb otg. Everything works fine through nightscout. I redid setup yesterday and selected G4-upload. The docs say G4-raw, but that was not one of the options in setup. Any idea why the blood glucose data isn't getting into the Edison?
that means it's a hardware issue. does the charging icon come on on the receiver when you plug it in? try reversing the direction of the OTG cable and see if you can get lsusb to show devices. there should be 3 (the one with no name is the Dex)
@tatigger For that setup (Explorer board connected to G4 by USB-OTG), you can't use a LiPo battery, you have to power the Explorer board through the USB port. If it's working, the charge indicator on the G4 receiver should show that it's charging; if you're powering it the wrong way, it won't.
Hi @jimrandomh, @scottleibrand, The light on the explorer board lights up when plugged in via usb to a power bank and/or directly to the wall. I have tried both power sources for the edison/exolorer board to use off-line blood sugars. The power was in the charge side and the otg was in the otg side of the explorer board, as labeled.
I do have a spare explorer board, but it is the older version. No time to do trace cutting etc before leaving....will try that next when I get back. I have tried to directly connect the G4 before, with no luck. Same rig. PS: used 2 different cables as well, same results.
One thing to watch out for, that matches the symptom you've got: mechanical damage to the USB ports. (I broke one Explorer block that way). When traveling, you want a rigid case with the blocky parts of the USB cables fully inside and covered, so they're protected from impact.
