Several Months ago I commenced a project to passively monitor health signals including body Temperature.
I focused around Arduino and hoped to scan one or more implant as I walk through a door-way.
After a fair bit or research and speaking with Amal Graafstra [Dangerous Things] he indicated no Arduino code had been created to read the xBT chip. Below is a usable sketch which hopefully save someone alot of time which Amal has encouraged me to now post.
To read such a chip requires a read capable of FDX-B protocol.
For this purpose of writing and testing I’ve chosen the RFIDRW-E-TTL chip from Priority1 (below).
The larger intent for this project is a doorway scanner which I’d adapt/build directly.
Its become apparent that the power output required to scan a 2*12mm chip from 1m is problematic, possibly dangerous. As such I am exploring alternatives to passive scanning…
