Dexcom G6

Basics first

  • Follow general CGM hygiene and setting sensor recommendation here.
  • For G6 transmitters manufactured after fall/end of 2018 please make sure to use one of the latest nightly built xDrip+ versions. Those transmitters have a new firmware and latest stable version of xDrip+ (2019/01/10) cannot deal with it.

General hints for looping with G6

Dexcom G6를 사용하는 것은 맨 처음 육안으로 보여지는 것 보다 좀더 복잡합니다. 그것을 안전하게 사용하기 위해서는 , 몇가지 인지하고 넘어갈 것들이 있습니다.

  • If you are using the native data with the calibration code in xDrip+ or Spike, the safest thing to do is not allow preemptive restarts of the sensor.
  • If you must use preemptive restarts, then make sure you insert at a time of day where you can observe the change and calibrate if necessary.
  • If you are restarting sensors, either do it without the factory calibration for safest results on days 11 and 12, or ensure you are ready to calibrate and keep an eye on variation.
  • Pre-soaking of the G6 with factory calibration is likely to give variation in results. 만일 당신이 Pre-soak을 한다면, 가장 정확한 결과값을 얻기위해 센서보정을 할 필요가 있습니다.
  • If you aren’t being observant about the changes that may be taking place, it may be better to revert to non-factory-calibrated mode and use the system like a G5.

If using G6 with xDrip+

  • The Dexcom G6 transmitter can simultaneously be connected to the Dexcom receiver (or alternatively the t:slim pump) and one app on your phone.
  • When using xDrip+ as receiver uninstall Dexcom app first. You cannot connect xDrip+ and Dexcom app with the transmitter at the same time!
  • If you need Clarity and want to profit from xDrip+ alarms use the patched Dexcom app with local broadcast to xDrip+.
  • If not already set up then download xdrip and follow instructions on nightscout (G5).
  • Select xDrip+ in ConfigBuilder (setting in AndroidAPS).
  • Adjust settings in xDrip+ according to xDrip+ settings page
  • If AAPS does not receive BG values when phone is in airplane mode use Identify receiver as describe on xDrip+ settings page.

If using G6 with patched Dexcom app

  • Download the apk from https://github.com/dexcomapp/dexcomapp, and choose the version that fits your needs (mg/dl or mmol/l version, G6).

  • 오리지날 Dexcom 앱이 남아 있는 경우 센서를 스탑하고 삭제합니다.

  • 다운로드 된 apk를 설치합니다.

  • 센서를 시작합니다.

  • Select Dexcom App (patched) in ConfigBuilder (setting in AndroidAPS).

  • If you want to use xDrip+ alarms via local broadcast: in xDrip+ hamburger menu > settings > hardware data source > 640G /EverSense.

  • There is no local broadcast from patched Dexcom app directly to xDrip+. Broadcast has to go through AAPS as described above.

Troubleshooting G6

Dexcom G6 specific troubleshooting

  • Transmitters with serial no. starting with 80 or 81 need at least last stable xDrip+ version from May 2019 or a newer nightly build.
  • Transmitters with serial no. starting with 8G need at least nightly build from July 25th, 2019 or newer.
  • xDrip+ and Dexcom app cannot be connected with the transmitter at the same time.
  • Wait at least 15 min. between stopping and starting a sensor.
  • Do not rewind back time of insertion. Answer question “Did you insert it today?” always with “Yes, today”.
  • Do not enable “restart sensors” while setting a new sensor
  • Do not start new sensor before the following information is shown in Classic Status Page -> G5/G6 status -> PhoneServiceState:
    • Transmitter serial starting with 80 or 81: “Got data hh:mm” (i.e. “Got data 19:04”)
    • Transmitter serial starting with 8G or 8H: “Got glucose hh:mm” (i.e. “Got glucose 19:04”) or “Got no raw hh:mm” (i.e. “Got now raw 19:04”)

New transmitter with running sensor

If you happen to change transmitter during a running sensor session you might try to remove the transmitter without damaging the sensor mount. A video can be found at https://youtu.be/AAhBVsc6NZo.
