## ## **FIGURE 2-12: BM78SPPS5MC2/NC2 REFERENCE CIRCUIT** ## **BM78** ## **3.0 OPERATING PATTERN** The BM78 provides two operating patterns, Auto Pattern and Manual Pattern, and the operating modes can be configured through the UI tool or the host MCU. See Figure 3-1. If the Auto_Pattern_Setting parameter is enabled, the BM78 triggers the Auto Pattern state machine otherwise Manual Pattern is used. Configure mode is available only in Auto Pattern and it can be enabled or disabled by the UI settings or host MCU. ## **FIGURE 3-1: OPERATING PATTERN CONFIGURATION** **Advance Information** DS60001380A-Page 23  2016 Microchip Technology Inc. **BM78** ## **3.1 Auto Pattern** In Auto Pattern, the BM78 automatically operates after power on without any interference from the MCU. Auto Pattern is the basic application of the BM78. Figure 3-2 illustrates the characteristics of Auto Pattern. ## **FIGURE 3-2: AUTO PATTERN CHARACTERISTIC** Although the BM78 is set to operate in Auto Pattern mode, it provides the flexibility for the MCU to perform some specific settings in Configure mode by command set. If the BM78 has enabled authenticated pairing, the command set is required to accomplish the Bluetooth link. The MCU doesn’t have to deal with the BM78 state, and the BM78 changes its state after power on. However, the MCU can terminate the connection by using GPIOs. The transparent pipe is used for application data transmission and data is transmitted between the remote host and MCU. The MCU knows the state of the BM78 by GPIOs. The configure mode is available only in Auto Pattern and it can be enabled or disabled by UI tool settings. Basically, the MCU is communicating with the BM78 by GPIOs, except for data transmission. **Advance Information** DS60001380A-Page 24  2016 Microchip Technology Inc. **BM78** Figure 3-3 illustrates how the BM78 changes its own state. After power on, there are two options, one is to enter Stand-by mode and the other is to enter Link-Back mode, and it depends on if any device is recorded in the BM78. Irrespective of the mode, the BM78 waits for the remote side to establish a connection or tries to establish a connection with the remote side. Once the connection is established, the state of the BM78 changes to connected mode. If the connection is terminated, the BM78 goes into Deep-Sleep mode. **Note:** Link-Back mode is available only for SPP profile or mode. ## **FIGURE 3-3: BM78 INTERNAL STATE MACHINE** The BM78 stays in Access state and it is ready for a remote host to access. It either waits for the remote side to create a connection or tries to create a connection on its own. ## **TABLE 3-1: STATE INDICATION** |**State**|**Mode**| |---|---| |Access State|Configure Mode
Stand-by Mode
Link-Back mode
PairingProcedure| |Link State|Connected Mode| |Deep-sleepState|Deep-SleepMode| Configure mode and pairing procedure are also defined as Access state. If the BM78 enters link state, it means not only the Bluetooth link has been established successfully, but also the data session is triggered. MCUs can transmit data to a remote host or receive data from a remote host in this state. **Advance Information** DS60001380A-Page 25  2016 Microchip Technology Inc. ## **BM78** 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. ## **FIGURE 3-4: AUTO PATTERN TRANSPARENT PIPE** ## **3.2 Manual Pattern** In Manual Pattern, the MCU communicates with the BM78 using command sets. The MCU must send correct commands to handle the state of the BM78. The change in the BM78 state is based on the MCU commands. 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 follow the command set rule. This is defined as protocol pipe. In Manual Pattern, the MCU can get the detail status by the BM78_Status_Report event. Figure 3-5 illustrates the characteristics of Manual Pattern. ## **FIGURE 3-5: MANUAL PATTERN CHARACTERISTICS** **Advance Information** DS60001380A-Page 26  2016 Microchip Technology Inc. **BM78** Figure 3-6 illustrates the MCU state change in Manual Pattern. For Manual Pattern, all MCU state change requires a corresponding command. For example, the MCU sends the `Invisible_Setting` command with the parameter `Enter_Standby_Mode` , then the BM78 goes into stand-by mode. The MCU sends the `SPP_Create_Link` command, then BM78 goes into Link-Back mode. nection is terminated. The MCU should decide on the mode of the BM78 once the connection is terminated, that is based on the overall system behavior. In Auto Pattern, the BM78 goes into Deep-Sleep mode once the connection is terminated, and in Manual Pattern the BM78 stays in Idle mode even after the con- ## **FIGURE 3-6: STATE CHANGES BY MCU IN MANUAL PATTERN** **Advance Information** DS60001380A-Page 27  2016 Microchip Technology Inc. **BM78** Figure 3-7 illustrates the Manual Pattern protocol pipe. If the MCU wants to send data (12345) to remote side, the data format should follow the UART command protocol. **FIGURE 3-7: MANUAL PATTERN PROTOCOL PIPE** **Advance Information** DS60001380A-Page 28  2016 Microchip Technology Inc. **BM78** ## **3.3 Mode Definition** ## 3.3.1 CONFIGURE MODE The Configure mode configures the relative settings before the BM78 enters into Auto Pattern state. If Configure mode is enabled, the BM78 will send Configure mode status event to notify the MCU that the BM78 is ready to receive commands. If the BM78 doesn’t receive any valid command within the specified Configure mode time, it will exit from Configure mode automatically.

For best range performance, keep all external metal at least 31 mm away from the ceramic chip antenna. Avoid top copper layer near the test pin area. When designing the host PCB, the areas under the antenna should not contain any top, inner, or bottom copper layer. A low-impedance ground plane will ensure best radio performance (best range and lowest noise). The ground plane can be extended beyond the minimum **FIGURE 6-3: BM78SPPS5MC2/NC2 HOST PCB MOUNTING SUGGESTION** **Advance Information** DS60001380A-Page 39  2016 Microchip Technology Inc. **BM78** Figure 6-4 illustrates the physical dimensions of the BM78SPP05MC2/NC2 module. ## **FIGURE 6-4: BM78SPP05MC2/NC2 MODULE DIMENSIONS** **Advance Information** DS60001380APage 40  2016 Microchip Technology Inc. **BM78** Figure 6-5 illustrates the recommended host PCB foot print. ## **FIGURE 6-5: BM78SPP05MC2/NC2 RECOMMENDED PCB FOOTPRINT** **Advance Information** DS60001380A-Page 41  2016 Microchip Technology Inc. ## **BM78** Figure 6-6 illustrates the recommended mounting details for the BM78SPP05MC2/NC2 module and recommended layout of the host PCB. possible for minimum loss and better impedance matching.
