piBeacon: 7- tested Beacons

try: "nonda iHere Key Finder - gen 2" on amazon. $20,
works fine, has a rechargeable battery, charge last > 1 month

a little bigger than the xy, but you can recharge

piBeacon: 7- tested Beacons

feedback on nano ihere 3 and aiko

the nado- ihere version 3 works fine,

the nado aiko also, but needs a different iPhone app.

It seems they do not send any iBeacons signals when the iPhone app is active.

the nado aiko looks really slick. Will be WA!


all of them have the same UUID: 005b0200239be11102d1001c00000319-2-522

Re: piBeacon: 7- tested Beacons

To calibrate the transmit power -- This process is true for iBeacons as well as BLEconnect:

It is important to get that number right in iBeacon device edit.
The meaning of TX-power data from the iBeacons varies. For some (eg xy,.. ) it is correct. Others show an indicator of the strength: 0-8 - not the dBm.
If the number is around -40--60 in txPower it is likely correct (for iBeacons not for BLEconnect they have much higher regular txPowers)

Do the following:
1. place the iBeacom 1 meter away from an RPI - direct line of sight
2. wait 1+ minute
3. check the RSSI value (signal) of the iBEacon for that RPI.
4. edit beacon device
5. enter the measured signal value @ 1m into the "== Set txPower, use number ... " field
6. save

Then the distance valuation will be (much) more accurate.
