@Hammer , @luxmatic - Do you notice more problems with the X2 reception of the G5 transmitter when you are home?
Wifi when running on the 2.4 GHz can cause interference with Bluetooth. I am only wondering if the X2/G5 connection is already susceptible to such interference maybe the Wifi pushes it over the edge?
Most modern routers support both the (older) 2.4 GHz and the (newer) 5 GHz bands. If you do think you are getting more interference at home and if your house Wifi is running both 2.4 GHz and 5 GHz and if you don’t have any older devices that only operate on 2.4 GHz then it would be interesting to turn off the 2.4 GHz broadcast from your wireless access point (probably the router or modem or whatever integrated device the provider might have given you) and see if it makes any difference at all?
Similar if you are running any of the 2.4 GHz cordless phones rather then the 5 GHz cordless phones. Not that you can just easily switch your cordless phone from 2.4 GHz to 5 Ghz but you could power down the base phone transmitters for a few hours and see if it makes a difference? Baby monitors running on 2.4 GHz.
Just trying to think if it could be any other devices in the house that might be adding to a less than stellar situation?
With that being said, I would have been happier from the get go if Dexcom had built the G5 (and upcoming G6) with three Bluetooth advertising channels instead of the 2 advertising channels (and 1 data channel) that the G5/G6 transmitters have. Tandem of course has to use what is there but Dexcom potentially could have added a third advertising channel. The purpose of three Bluetooth advertising channels is they all run in the basic 2.4 GHz spectrum but in all slightly different frequencies within that broader 2.4 GHz so as to increase the probability of getting a signal through even in “crowded” or “noisy” environments.
