7. System function
How to wake up module from sleep mode?
There are two ways to wake up module from sleep mode.
7.1 Send “I am iron man, I am iron man, I am iron man I am iron…..” string.
Yes, that is a joke, in sleep mode, you can send a long string (Length >
80 or more), that string can made module wake up, and you will receive
“OK+WAKE” string through UART. That string can’t include any AT commands.
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?
In discoverable mode, send “AT+SLEEP” string through UART, if all is okay,
module will return “OK+SLEEP” string and into sleep mode.
HM Bluetooth module datasheet
-------------------------------------------------------Last Version V530 2014-08-05 １６
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.
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):
When not connected, through the AT command configuration module,
connection, only for serial data transmission.
B) Mode 1(PIO acquisition mode):
When not connected, through the AT command configuration module,
connection, a) serial data transmission. b) Control of the PIO2,3 output
state(HM-11 has none). c) The acquisition of PIO4 ~ 11 input state(HM-11 only
PIO2,3).
C) Mode 2(Remote control mode):
When not connected, through the AT command configuration module,
connection, a) serial data transmission. b) Control of the PIO2~11 output
state(HM-11 only PIO2,3).
