Check whether the Baud rate of Promi-ESD is same as that of its host
equipment. If you do not know the current Baud rate of Promi-ESD, initialize it
to 9600 by pressing Reset.
Check whether the Data bit is set to 8. Promi-ESD supports only 8 Data bit. If
your host equipment uses 7 Data bit and even or odd parity, it can work as if it
uses 8 Data bit and No parity. This is valid only when both DCE devices are
Promi-ESD. In this case, set both Promi-ESDs to 8 Data bit and No parity. If
one of DCE devices is other Bluetooth device such as Bluetooth USB dongle,
please contact Technical Support.
Check whether the Parity and Stop bit of Promi-ESD are same as those of its
host equipment. Promi-ESD supports No parity, Even parity and Odd parity, 1
and 2 Stop bit.
Check whether the host equipment of Promi-ESD uses Hardware Flow Control.
Promi-ESD is initially set to Use of Hardware Flow Control. If your host
equipment does not use Hardware Flow Control, set the Hardware Flow Control
of Promi-ESD to No use.
And Promi-ESD does not support RS-232 break signal.
Data Loss or Malfunctioning
 Hardware Flow Control
When transmitting large data with No use of Hardware Flow Control, Promi-ESD
will clear the data buffer unexpectedly. This possibility goes higher as the RF
transmission environment is bad.
 ESD Response
The messages of ESD response may affect the function of host system. Set
ATS10=0 not to send ESD response to host system and try again. Refer
Appendix B. for details.
