Left is HM-10S, it has 34 Pads. Right is HM-10C and it only have 26 Pads HM-10C is cheaper than HM-10S.

There have a lot of fake version in the market, please look at carefully, we put “HM-10” and “HM-11” string on the top layer and the bottom layer,

5.1 HM-10 Schematic

5.2 HM-10 Size

6.3 HM-10 package information

6.4 HM-10 Device Terminal Functions

6.5 HM-11 Size

5.6 HM-11 Package information

5.7 HM-11 Device Terminal Functions

5.8 HM-15

HM-15 is based HM-10, a real USB interface.

5.9 HM-Sensor

HM-Sensor version is different HMSoft version. HM-Sensor support DHT11 and DS18B20.

5. System role

Module support Peripheral role and central role; Switch AT command is “AT+ROLE<P1>”. “AT+ROLE0” is peripheral role, “AT+ROLE1” is central role

                    Peripheral role

If AT+IMME0 is setup module will auto into discoverable mode.

If AT+IMME1 is setup, module will do nothing, you can use AT command setup module, then use AT+START to start device.

                    Central role

Central role support two work methods.

Automatic-scan-connect mode (AT+IMME0) and Command-scan-connect mode (AT+IMME1).

In AT+IMME0 mode, when power on, module will check if have a device addresshave already success connect before. If have, module will try to connect that device for ever, if we setup AT+TCON, when AT+TCON value timeout, module will forget that device and try scan devices, then try connect the device what we scanned; If not have a device address, then module will try scan devices and try connect them. AT+SAVE command will let module know if save devices address or not.

In AT+IMME1 modem, when power on, module do nothing, module will wait your command, now you can use AT+DISC? Or AT+DISI? Or AT+DISA? Command to         scan devices. Also, you can use AT+CO command connect to a device.

6. System function

How to wake up module from sleep mode?

There are two ways to wake up module from sleep mode, if module was in sleep mode.

7.1 Send “I am iron man, I am iron man, I am iron man I am iron” strings.

Yes, that’s a joke, in sleep mode, you can send a long string (Length > 1024 or more), that string can caused module wake up, and you will be received “OK+WAKE” string from module UART. Note: That wake-up string is better not including any AT commands.

Since V607/V702, we made wakeup function better, doesn’t need 80 strings anymore, you only need send 1-3 bytes to wakeup module.

7.2 Long press system KEY >=1000 ms.

After wake-up module, you can send and receive AT commands.

                          How to let module into sleep mode?

1. Send “AT+SLEEP” string through UART, if all is okay, module will return “OK+SLEEP” string and into sleep mode, this command only take effect once more.

2. Execute “AT+PWRM1” command, Module will auto into sleep mode when power on or disconnect from remote device. This command only need setup once more.

                         System advert packet

In iOS system you can’t get module MAC address directly. So, we put MAC

       address information into advert packet.

You can use CBAdvertisementDataManufactureDataKey property to get it, MAC address information string format like follow:

Total length is 8 Bytes, first of two bytes is identify string, it always is 0×48 and 0x4D, the rest 6 bytes is MAC address string

For example: 0×48, 0x4D, 0xB4, 0×99, 0x4C, 0xXX, 0xXX, 0xXX 0×48 and 0x4D is “HM” string.

0xB4: 0×99: 0x4C: 0xXX: 0xXX: 0xXX is BLE MAC Address.

System KEY function (PIO0)

Press if Low > 1000ms:

7.3.1 If Module is in sleep mode

Module will wake up immediately, if AT+NOTI value is “1”, module will send “OK+WAKE” string through UART.

7.3.2 If Module has already connected to remote device Module will disconnect from remote device.

7.3.3 If Module is standby mode

Module will reset to default configuration. Then restart. You can use AT+PIO01 command to close this function.

System LED function (PIO1)

In sleep mode, LED has turned off.

If AT+PIO10 is setup

Unconnected status: Output High 500 ms, Low 500 ms Connected status: Output High

If AT+PIO11 is setup Unconnected status: Output Low. Connected status: Output High.

System work Mode

A) Mode 0(Transmission mode, command string: “AT+MODE0”):

Before connect, you can configure module parameters with AT Commands After connect, you can send and receive Bluetooth data through UART.

B) Mode 1(PIO acquisition mode, command string: “AT+MODE1”):

Before connect, you can configure module parameters with AT Commands After connect

1) Send and receive Bluetooth data through UART.

2) Remote device could configure module parameters with AT Commands

3) Remote device could control PIO2 and PIO3 output low or high with AT Commands

HM-11 has no this function

4) Remote device could get PIO4 ~ 11 input status with AT Commands HM-11 only has PIO2 and PIO3.

C) Mode 2 (Remote control mode command string: “AT+MODE2”):

Before connect, you can configure module parameters with AT Commands After connect:

1) Send and receive Bluetooth data through UART.

2) Remote device could configure module parameters with AT Commands

3) Remote device could control PIO2~11 output low or high HM-11 only has PIO2 and PIO3.

7. AT Commands

Factory default setting:

V5xx: Name: HMSoft; Baud: 9600, N, 8, 1; AT+NOTI0; Peripheral Role;

transmit mode.

V6xx: Name: HMSoft; Baud: 9600, N, 8, 1; AT+NOTI1; Peripheral Role; Remote-Control mode.

V7xx: Name: HMSoft; Baud: 115200, N, 8, 1; AT+NOTI1; Peripheral Role; Remote-Control mode.

AT Command format:

Uppercase AT command format. string format.

V5xx, module didn’t accept command ended with any other symbol. (e.g. r orn).

V6xx, module accept more Freestyle when you use command through UART. V7xx, if you send command ended with CRLF, then module response string

would be added CRLF. If you not then module not. You jump, module jump. AT command through UART support more Freestyle.

On Transmit version: module only accept AT Commands from UART interface when Bluetooth device is not connected with remote device.

On Remote version: module could accept AT Command from UART interface when Bluetooth Device is not connected with remote device, Also could accept AT          Command from remote Bluetooth device when connected that.

On PIO collection version: module only accept AT Command from UART interface when Bluetooth device is not connected with remote device. After connect with          remote device, module could accept and execute AT Command send from remote side.

Note: All command value will be saved in internal flash, doesn’t need setup many times.

Note: “[” and “]” is not part of the command.

1. Test Command or Disconnect Comman

If module is in sleep mode, module will output “OK+WAKE” and into standby mode. If Module is not connected to remote device, you will receive: “OK”

If Module is connected, module will be disconnected from remote device, if “AT + NOTI” is setup to 1, module will output “OK+LOST” through UART.
