The messages of WCS-232 response may affect the function of host system. Set ATS10=0 not to send WCS-
232 response to host system and try again. Refer Appendix B. for details.

Transmission Delay
D.3.1.
RF Processing Delay
It takes 30msec approximately for a WCS-232 to complete a data transmission to the other Bluetooth
device. This time delay cannot be reduced and may enlarge as the RF transmission environment
becomes worse. Do not use WCS-232 If your applications cannot allow for this time delay.
D.3.2.
RF Transmission Environment
If there are many Bluetooth devices working in a small area and/or the RF communication distance is
too great and/or there are some obstacles affecting RF performance, the WCS-232 repeats the
transmission packet by packet due to interferences and/or low RF performance. This may lead to
increased data transmission time delays.
