Promi-ESD User Manual – Trouble Shooting 33

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.
