Appendix D: Trouble Shooting
D.1. No Data Transmission
D.1.1. Device Settings
Check whether the Baud rate of Parani-BCD110V3 matches that of its host equipment.
Check whether the host equipment of Parani-BCD110V3 uses Hardware Flow Control. Parani-
BCD110V3 is initially set to Use of Hardware Flow Control. If your host equipment does not use
Hardware Flow Control, please disable the Hardware flow control option by ParaniWIN or AT
command.
D.2. Data Loss or Malfunctioning
D.2.1. Hardware Flow Control
When transmitting large amounts of data with No Hardware Flow Control, Parani-BCD110V3 may
clear the data buffer unexpectedly. The possibility becomes greater as the RF transmission
environment becomes worse.
D.2.2. Response Message
The messages of Parani-BCD110V3 response may affect the function of host system. Set ATS10=0 not
to send Parani-BCD110V3 response to host system and try again. Refer Appendix B. for details.
D.3. Transmission Delay
D.3.1. RF Processing Delay
It takes 30msec approximately for a Parani-BCD110V3 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 Parani-BCD110V3. 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 Parani-BCD110V3
repeats the transmission packet by packet due to interferences and/or low RF performance. This
may lead to increased data transmission time delays.
