switch.
2.2.1. Data Bit
Parani-ESD supports only 8 data bit. In the case of 7 data bit, please contact the technical support.
2.2.2. Hardware Flow Control
Parani-ESD plugged into its host system transmits data from host to the other side Bluetooth device.
These data is saved temporarily in the internal buffer of Parani-ESD and sent repeatedly until the
transmission is completed packet by packet. When the radio transmission condition is not good
enough to send data promptly, it can cause the transmission delay. If the host sends more data when
the buffer is full, buffer overflow will make Parani-ESD malfunction consequently. In order to prevent
this buffer overflow, Parani-ESD works as follows.
In case of using hardware flow control, Parani-ESD makes RTS be ‘disable’ to stop receiving further
data from the host when the buffer becomes full. RTS will be ‘able’ to begin receiving data again from
the host when the buffer has some room for more data.
In case of not using hardware flow control, Parani-ESD clears the buffer to secure the room for next
data when the buffer becomes full. This means the loss of data. As the transmission data becomes
large, the possibility of data loss goes higher.
For large data transmission, use of hardware flow control is highly recommended.
