 Data Bit

 Hardware Flow Control
Promi -SD 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 Promi-SD 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 Promi-SD malfunction consequently. In
order to prevent this buffer overflow, Promi -SD works as follows.
