Im using the G6 with xDrip+ nightly on Samsung A8 but I cannot get any readings when turning on the “OB1 collector”. It works when turning this OFF but then I need to calibrate my sensor which I want to avoid. Symptoms when “OB1 collector” is ON: “Signal Missed” on main page and System Status showing “Sensor Status: Stopped” while is still shows “Got data xx:xx” every 5 minutes! So it obviously receives data from the transmitter but it does not show in xDrip+! Why? Any hints?? Thanks a lot! ---

Hi @emp00 First, welcome to FUD. Make sure you go to our introduce yourself thread and introduce yourself! > [@Welcome, introduce yourself here!](https://forum.fudiabetes.org/t/welcome-introduce-yourself-here/145): > > Hello, welcome to FUDiabetes (For Unlimited Diabetes). We’re happy to have you here and look forward to sharing, learning, and exploring all things diabetes together. I’m Sam, formerly known as Sam19. I live in Alaska with my wife and 2 young children. I was diagnosed with T1 unexpectedly at age 29. I currently manage with tresiba, novolog MDI, and Afrezza. I use a dexcom G5 cgm intermittently. Nice to meet you all. Now, about your problem. Go to settings\>less common settings\>other misc options and make sure “Samsung Workarounds” is checked. With the G6 you should also be using “native mode”, in G5/G6 Debug. And while you’re there make sure “I am Using G6” is checked. Try these and let me know if it now works. ---

Hi @docslotnick, thank you very much for the reply. However, I checked all options you mentioned “Samsung Workarounds”, “Native Mode” and “I am Using G6” ==\> all are switched ON. Whenever I switch on “Use the OB1 Collector” this error appears right away: “Calibration rejected: Sensor stopped”. The other symptoms described in my intial post still apply. ☹ I still can only get xDrip+ to receive bg when switching “OB1 Collector” OFF. Why? What else can I do? Thanks again!! ---

@emp00 In Less Common Settings, go to Advanced calibration\>Use treatment glucose values and select to always ask first. Then when you enter a Bg value in the treatment panel it will ask if you want to calibrate. For some reason this seems a bit more forgiving on the calibration slope. ---

@docslotnick Do you mean with this setting the “OB1 Collector” should be working? Seems rather that this only enables a prompt asking to optionally using entered Bg values for the calibration. However, I wanted to avoid calibration completely since the G6 is supposed to not require this. Maybe as a workaround, can I manually set the calibration slope to 1.00 and intercept to 0.00 ?? Then xDrip+ would display the raw G6 values which is what I want, right? Still I would be highly interested getting this “OB1 Collector” working which should avoid these workarounds… I don’t understand why this does not fly. ---

@emp00, sorry I can’t help you, I don’t have the required info—but I still want to say welcome to the forum!
