### Vulnerability
As no formal pairing is completed, this is susceptible to MAC address spoofing, and so should only be used when paired with additional authentication factors.

### Usage
Configure env.sh with the devices you want to monitor. The environment variables must have an _%d suffix, in series, starting from 0.
```bash
#/bin/bash
export btmacaddress_0="69:42:69:FF:04:20" # your phone
export btmacaddress_1="0F:F0:0F:F6:44:55" # your smart watch
export btmacaddress_2="0F:44:24:F5:69:69" # your tablet
```
Then source the env.sh file to load the variables, build the program with go and then run it.
```bash
source env.sh
go build . & & ./embedded-bt-rssi-monitor
```
