FAQ: transmission frequency

The frequency (inverse (?) of the the interval ) for the distributed firmware is different for each mode,

version	raw (highres) ms	URL ms
		coded	measured
2.2.0
1.2.0	500	500	508
1.0.0	500	500 'A'

This seemingly very rapid transmission is an attempt to remediate the inherent poor percentage of sucessful packet reception of the BLE packets.

Here is a sample of packet reception times as seen by a raspberry pi zero using hcidump -t.
Nothing was moving however notice the missing samples. RSSI varied between -54 and -74 averaging -68 :

 15:06:03.392

 15:06:04.403
 15:06:04.905
 15:06:05.408
 15:06:05.917
 15:06:06.420

 15:06:07.435
 15:06:07.936
 15:06:08.442
 15:06:08.951
 15:06:09.453
 15:06:09.960
 15:06:10.463
 15:06:10.971

 15:06:11.981

 15:06:12.989
 15:06:14.008
 15:06:14.516
 15:06:15.024
 15:06:15.529

Reducing the frequency would have minimal effect on the battery lifetime.
