18
+The difference between BC04-B and BC04-A:
19
+
20
+BC04-B is a master-slave integrated Bluetooth serial port module. The master-slave command can be switched and the commands are rich and complete.
21
+
22
+BC04-A is a slave module product. It can only be used as a slave. It is factory-set. It is easy to use and cheap.
23

24
+## Product description
25
+
26
+
27

+## Product application
41
+
42
+This module is mainly used in the field of short-distance data wireless transmission. It can be easily connected to the Bluetooth device of the PC, and can also communicate data between the two modules. It avoids cumbersome cable connections and can directly replace serial cables.

+## Note

61
+Product characteristics
62
+
63
+1. The power supply voltage is 3.3V, the current is about 2-10mA when not paired, and about 20mA after pairing. It is absolutely forbidden to connect the power supply reversely!
64
+
65
+2. The LED pin indicates the Bluetooth connection status. The output pulse indicates that there is no Bluetooth connection. The high output indicates that Bluetooth is connected and the port is open.
66
+
67
+3. The interface level is 3.3V, which can be directly connected to various microcontrollers (51, AVR, PIC, ARM, MSP430, etc.). 5V microcontrollers can also be directly connected, without MAX232 and cannot pass through MAX232!
68
+
69
+4. Connect the module to the computer, connect the MAX3232 chip and then the serial port of the computer
70
+
71
+5. The effective distance in open space is about 15 meters, but the connection quality at this distance is not guaranteed.
72
+
73
+6. After pairing, it will be used as a full-duplex serial port. There is no need to know any Bluetooth protocol, but it only supports the communication format of 8 data bits, 1 stop bit, and no parity check. This is also the most commonly used communication format and does not support other formats. .
74
+
75
+7. When a Bluetooth connection is not established, it supports setting the baud rate, name, and pairing password through AT commands, and the set parameters are saved after power off. Automatically switches to transparent transmission mode after Bluetooth connection
76
+
77
+8. Small size (2.7cm*1.3cm), factory patch production to ensure patch quality.
78
+
79
+9. This link is a slave machine. The slave machine can be paired with various computers with Bluetooth functions, Bluetooth hosts, most mobile phones with Bluetooth, PDAs, PSPs and other smart terminals. Slave machines cannot be paired with each other.

81
+## Mode Setup
82
+
83
+Methods and steps for setting the module master-slave mode:
84
+
85
+### Hardware setup:
86
+
87
+Master mode:
88
+
89
+1. Set PI0(4)—software/hardware master-slave setting port: low (or left floating) to set the master-slave mode for the hardware
90
+
91
+2. Set PIO(5)—hardware master-slave setting port: to 3.3V high level
92
+
93
+
94
+Slave mode:
95
+
96
+1. Set PI0(4) - software/hardware master-slave setting port: low (or left floating) to set the master-slave mode for the hardware
97
+
98
+2. Set PIO (5) - hardware master-slave setting port: grounded (or left floating)
99
+
100
+
101
+
102
+### Software settings:
103
+
104
+Master mode:
105
+
106
+1. Set PI0(4) - software/hardware master-slave setting port: to 3.3V high level
107
+
108
+2. Open HyperTerminal or other serial port debugging tools and set the baud rate to 9600, 8 data bits, 1 stop bit, no parity bit, and no flow control.
109
+
110
+3. The serial port sends the character "AT+ ROLE1" and successfully returns "+ROLE=1 OK", which is carriage return and line feed.
111
+
112
+
113
+Slave mode:
114
+
115
+1. Set PI0(4) - software/hardware master-slave setting port: to 3.3V high level
116
+
117
+2. Open HyperTerminal or other serial port debugging tools and set the baud rate to 9600, 8 data bits, 1 stop bit, no parity bit, and no flow control.
118
+
119
+3. The serial port sends the character "AT+ ROLE0", and successfully returns "+ROLE=0 OK", which is carriage return and line feed.
