Figure 3-4 illustrates Auto Pattern transparent pipe. If

MCU wants to send data (12345) to the remote side,

the data should be in the.hex format to the BM78 and

the BM78 transmits the received data to the remote

side. Similarly, if the BM78 receives data from the

remote host, it sends the data in the.hex format to the

MCU.

Manual Pattern

In Manual Pattern, the MCU communicates with the

BM78 using command sets. The MCU must send cor-

rect commands to handle the state of the BM78. The

change in the BM78 state is based on the MCU com-

mands.

The data pipe for Manual Pattern is different from Auto

Pattern. Since the MCU is communicating with the

MCU by command sets, the data transmission will fol-

low the command set rule. This is defined as protocol

pipe. In Manual Pattern, the MCU can get the detail sta-

tus by the BM78_Status_Report event.

Figure 3-5 illustrates the characteristics of Manual Pat-

tern.
