It takes 30msec approximately for a Promi-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 Promi-ESD If your applications cannot allow this time delay.
 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, Promi-ESD repeats the transmission packet by packet due to
interferences and/or low RF performance. This leads the transmission time delay.
