AT instruction specification

specification

Applies to the entire document

{} : Including with {… .. The content in} is optional
<< : The host sent it to the module COMMAND
>> : The module replies to the host RESPONSE

Instruction

The command is the control command that the host actively sends to the module, and the module needs to reply <CR><LF>OK<CR><LF> as a response after receiving the command.

Instruction format

AT+Command{=Param1{,Param2{,Param3…}}}<CR><LF>

All instructions begin with AT and end with <CR><LF>
<CR> Indicates the carriage return character, corresponding to HEX is OxOD
<LF> Represents a newline character, corresponding to HEX is OxOA
If the instruction contains parameters, the parameters should be separated by =
If the instruction contains multiple parameters, the parameters should be separated by ,
If a response is returned, the response begins with <CR><LF> and ends with <CR><LF>
Modules should always return the result of instruction execution (OK on success, ERROR on failure)

Example:
Read module Bluetooth name
<< AT+VERSION
>> +VERSION：1.0.0,FSC-BT986
>> OK

Write to an unsupported baud rate
<< AT+BAUD=0
>> ERROR

Notification

The notification is the data that the module actively sends to the host. Generally used to indicate status changes or received data.

Notification format

<CR><LF>+Indication{=Param1{,Param2{,Param3…}}}<CR><LF>

All notifications begin with <CR><LF> and end with <CR><LF>
If the notification contains parameters, they should be placed after “=”
If the notification contains multiple parameters, the parameters should be separated by “,”

Example:
Return the current connection status in command mode
>> +SPPSTAT:3

Process for sending data

The module is powered on in a discoverable (visible) state by default, and the module is set to the state that needs to be paired, and the remote Bluetooth (mobile phone) can find and connect it, and initiate a connection request to the module. After the connection is successful, the module will raise the connection status pin to notify the host that the Bluetooth connection is successful. The host can send data to the remote Bluetooth through the Bluetooth module, and the remote Bluetooth can also send data to the host.

@startuml
hide footbox
skinparam sequenceMessageAlign center

box "local" #LightBlue
participant Host as host
participant Module as bt
end box

box "remote" #LightBlue
participant ”Remote BT“ as remote
end box

rnote over host, remote: Establish connection

bt --> remote: Visible mode
bt <- remote: Scan
bt --> remote: Need pairing
bt <- remote: Request to establish connection

rnote over host, remote: Connection successful

host <- bt: Pull up the connection status pin

rnote over host, remote: 发送数据

host -> bt: Serial port sending ABC
bt -> remote: Bluetooth sending ABC
bt <- remote: Bluetooth send DEF
host <- bt: Serial output DEF

bt <- remote: Disconnect Bluetooth

host <- bt: disconnect

host <- bt: Pull down the connection status pin

FAQ

IOS How does my phone get a Bluetooth MAC address?

For security reasons, the IOS system turns the Bluetooth MAC address into a UUID at the bottom layer and sends it to the upper-layer application. Therefore, the APP cannot obtain the MAC address of the device.

FSC-BT986_HC05 By default, the MAC address is placed in the broadcast. The APP can obtain the MAC address from the broadcast packet in the following way.

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
    if(![self describeDictonary:advertisementData])
    {
        NSLog(@"is not fsc module");
        return;
    }
}

- (Boolean)describeDictonary: (NSDictionary *) dict
{
    NSArray *keys;
    id key;
    keys = [dict allKeys];
    for(int i = 0; i < [keys count]; i++)
    {
        key = [keys objectAtIndex:i];
        if([key isEqualToString:@"kCBAdvDataManufacturerData"])
