we are now able to record bluetooth fingerprints

Browse Source 
for this, we use the same ui interface and fingerprint positions as wifi. if wifi has done 30 scans, also the ble
scans will be stopped. this is just a quick and dirte solution, as changing the gui completely for this two options
was to time consuming
