? 2016 microchip technology inc. advance information ds60001380a-page 23 bm78 3.0 operating pattern the bm78 provides two operating patterns, auto pat- tern 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 other- wise manual pattern is used. configure mode is avail- able only in auto pattern and it can be enabled or disabled by the ui settings or host mcu. figure 3-1: operatin g pattern configuration
bm78 ds60001380a-page 24 advance information ? 2016 microchip technology inc. 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. basi- cally, the mcu is communicating with the bm78 by gpios, except for data transmission.
? 2016 microchip technology inc. advance information ds60001380a-page 25 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 connec- tion 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 connec- tion is terminated, the bm78 goes into deep-sleep 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 connec- tion on its own. 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 suc- cessfully, 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. note: link-back mode is available only for spp profile or mode. table 3-1: state indication state mode access state configure mode stand-by mode link-back mode pairing procedure link state connected mode deep-sleep state deep-sleep mode
bm78 ds60001380a-page 26 advance information ? 2016 microchip technology inc. 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 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. figure 3-5: manual pattern characteristics
? 2016 microchip technology inc. advance information ds60001380a-page 27 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. in auto pattern, the bm78 goes into deep-sleep mode once the connection is terminated, and in manual pat- tern the bm78 stays in idle mode even after the con- 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. figure 3-6: state changes by mcu in manual pattern
bm78 ds60001380a-page 28 advance information ? 2016 microchip technology inc. 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
? 2016 microchip technology inc. advance information ds60001380a-page 29 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 con- figure 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 config- ure mode time, it will exit from configure mode auto- matically. once the mcu sends any valid command within the configure mode time, the bm78 will not exit configure mode until the mcu gives the leave config- ure mode command. once the bm78 exits from config- ure mode, it goes to process auto pattern state machine. figure 3-8: configure mode
