Libre 2 sensor taken apart

I ripped open a Libre 2 sensor. This is what the circuit board looks like:


 

 

 

 

 

 

 

 

 

According to a video which takes apart and explains a Libre sensor (https://www.youtube.com/watch?v=sYIm97wjl0o), the main chip is an rf430frl15xH. Documentation can be found here: https://www.ti.com/lit/ds/symlink/rf430frl153h.pdf?ts=1638446087729&ref_url=https%253A%252F%252Fwww.google.com%252F

The circuit board in the video looks looks largely similar to mine (Libre 2 EU), but there are some differences. My best guess is that the video is about a Libre 1 sensor, without bluetooth.

On the LimiTTer gitter (https://gitter.im/JoernL/LimiTTer?at=5c2eff506649aa1f82199078), Mathias Walter reported that an EM9304 (https://www.emmicroelectronic.com/product/standard-protocols/em9304) is used for the bluetooth. And that the NFC chip is RF430TAL160H.

The actual sensor that goes into skin is connected to the transparant plastic part. It looks like this on inside:





 

The three black dots is where the sensor connects to the circuit board. The actual sensor is on the other side (adhesive taken of here):

Glucose levels on a smartwatch without a phone nearby (Freestyle Libre 2 + Bubble Mini + Samsung Galaxy watch 4)

  I started using the Freestyle Libre 1 in July 2020, I switched to Libre 2 in April 2021. I was very happy with the alarms, but over time became annoyed by carrying around several devices. Because of the Bluetooth and NFC capabilities of the Libre sensors, I wondered: What if I had a watch with Bluetooth and/or NFC? It would eliminate the need to drag around a phone or reader, everywhere I go. After weeks of trial, error and endless web browsing, I have found myself a set-up that works. This is what it looks like:                     With my current set-up, I can always use the Libre 2 reader as a back-up, to scan the sensor and receive the high and low alarms. This is very important to me, because apps and bluetooth can fail to connect, often for unknown reasons. Below, you will find the steps I followed. Reading guide: If you just want to get readings from Freestyle Libre 2 sensors (on phone, and perhaps forward the readings to a smartwatch), without an additional device li

Troubleshooting issues with xDrip+ and Bubble Mini

Always keep location (GPS) on phone or watch turned on! Without it, bluetooth will likely NOT function or (re)connect. This may seem ridiculous and unnecessary, because that's what it is. In 2019, Android (read: Google) made it mandatory for any app to have location permission in order to work with Bluetooth devices. This is an abomination and drains battery, but cannot really be avoided.   Placing Bubble Mini on sensor Don't stick the Bubble to the sensor with adhesive, only to skin. This way, the Bubble may be less securely connected, but if sticked to the sensor, the Bubble causes additional friction and pull and the Libre sensor will likely fall of before the 14-day lifetime of the sensor. The Bubble may fall of once every few days, but is easily reattached. A sensor that comes loose from skin cannot be used anymore.  Manually check whether Bubble is positioned correctly over the sensor, before sticking it to skin. Before sticking the Bubble Mini to skin, it is best to fir
