Inaccurate results when using find-lf

[kmic25]

Hi, I've managed to set up find and find-lf using 5 Raspberry Pis. However I'm not getting accurate results.

My set-up:

• 1 Raspberry Pi running Find server
• 1 Raspberry Pi running Find-lf server
• 1 Raspberry Pi from where I'm initializing the cluser
• 3 Raspberry Pis (the one running the Find-lf server and another 2) within the cluser (set up in different corners of the room)

Initial plan was to have the one from where I'm initializing the cluser also part of the cluster, however I'm not managing to get it to work with that set-up (it never transmits even though the status says that it's running)

Currently my main issue though is that even after giving it quite some time to learn, it is still highly inaccurate and does not correctly guess which area I'm in - even if I'm exactly next to a PI which is in the cluster and if that's a place from where I initially set it to learn.

Some logs which might be helpful:

When set to learning mode:

fingerprint.go:241: Tracking fingerprint containing 1 APs for bcf5acdfa3d9 (mytest) at window (guess)

(In reality I was back to location 'my_desk' over here)

Any help is greatly appreciated. Thanks

Judging from your logs, it looks like you are only sending a single mac addresses? Can you verify whether your raspberry pi's have different hostnames (this is used to differentiate them).
