In my RFDuino version, the xmtr id is compiled into the code. Currently, I don't bother with checking the xmtr id. Even if you were close to another dexcom user, the odds of picking up their packets are fairly small. There's only a ~2 second interval every 5 minutes where you would be susceptible, and they would need to be on the same period as you also.Donhttps://www.blogger.com/profile/12447399246832399363noreply@blogger.comtag:blogger.com,1999:blog-2090121141266718432.post-57742172851045438682016-10-19T07:25:17.926-07:002016-10-19T07:25:17.926-07:00Hello Don,

It is available to any BLE central device as a peripheral. I use this with a custom iPhone app, pieces of which you see on Github. I don't do any work with Android.<br />The black connector is a pin header socket, it provides battery + and - as well as rx,tx and rst. Everything necessary to program the rfduino and charge the battery.

Also looks like another Redbear product. The RFDuino is also pretty small, spend the $10 on that. The next step for me would be a combination Central/Peripheral device, then you could be separated from a phone, except for calibration.Donhttps://www.blogger.com/profile/12447399246832399363noreply@blogger.comtag:blogger.com,1999:blog-2090121141266718432.post-3010978764286304092015-03-23T10:28:45.169-07:002015-03-23T10:28:45.169-07:00Hey, Don.

Saw your blog the other night while searching for a potential path to make my own CGM Watch, but I'm not completely competent with the electrical engineering side of the project. Would something like the XBAND work similarly to what you're creating?<br /><br />https://www.indiegogo.com/projects/xband-world-s-smallest-bluetooth-sensor-computerMikehttps://www.blogger.com/profile/16063164924644634717noreply@blogger.com
