D.3 Transmission Delay
D.3.1 RF Processing Delay
It takes 30msec approximately for a Parani-ESD to complete the data transmission to the other side
Bluetooth device. This time delay cannot be reduced and would be bigger as the RF transmission
environment is bad. Do not use Parani-ESD If your applications cannot allow this time delay.
D.3.2 RF Transmission Environment
If there are lots of Bluetooth device working in a small area and/or the RF communication distance is
too long and/or there are some obstacles affecting RF performance, Parani-ESD repeats the
transmission packet by packet due to interferences and/or low RF performance. This leads the
transmission time delay.
