Low power settings hint (enter sleep AT+SLEEP, wake on the falling edge of the
PWRC pin)
Broadcast mode power saving scheme
Broadcast shallow sleep: serial port to send AT+SLEEP or AT+SLEEP1, the current
can be set to lower through broadcast intervals
Deep sleep: serial send AT+SLEEP2, at this time the current in a few uA, this mode
is not broadcast
Connection mode power saving scheme
1: connection state needs low power consumption, the P01 pin is held low, AT
AT+SLEEP or AT+SLEEP1 command module into MCU to make sleep, when the
data will be P01 pulled high by the falling edge of the PWRC pin wake Bluetooth, so
you can ensure that the case in connection to the Bluetooth power consumption is
very low,
2: of course, you can also let the Bluetooth module and the user's MCU has been
sleeping, through the Bluetooth module to wake up the user's MCU, this way to do
more than 1 of the way to save power.
3: to reduce power consumption by setting the connection interval, this mode is
configured to save power by 1 and 2

delay through the AT command
The user needs to wake up the user MCU
via the P16 pin, and then send the data
back to the user MCU, which can be set by
the AT command

control pin
Low level AT mode with default high
level
This pin does not need to be sent AT if it
is connected
When the AT instruction in the state of
the connection request, the P01
pin is held low, in AT mode, the
user can then send the AT
command, to pass through the
data when P01 will maintain a
high level, immediately into
transmission mode
Is it necessary to send P01 to the low
level if the AT command is not
connected?
Answer: No, the module is AT mode in
an unconnected state. The user
does not need to send the AT
command in the case of
JDY-08
connection, and the P01 pin is
left unconnected

Bluetooth wakes up the user MCU,
then output XXms delay data to the

Default: 1
Special instructions: when set to 0-1, the connection pin P16 will have a change in the
connection state
Set 2-6, P16 is usually high, there is connection or APP data down, the module generates
a drop edge delay pulse, low level delay time, please according to the above delay
parameters through the AT instruction adjustment
This instruction is very useful for low power consumption products require a higher, and
this ensures that users of MCU can be normal in a sleep state, when the data is coming to
wake the user's MCU, and then the output data to the user MCU

AT+ CLSS description:
Where is the difference between AT+ CLSS and AT+HOSTEN (module work mode
instructions)?
Answer: the AT+ CLSS device type is the device type of the AT+HOSTEN
Example 1: the user wants to configure the LED ribbon type to send AT instructions as
follows
1:AT+HOSTEN0 / / configured transparent transmission mode
2: AT+ CLSSB1 / / LED configuration into the lamp type
3: send AT+RST / reset
You configure the LED device type through the 3 steps above
Example 2: the user wants to configure the iBeacon type to send the AT instruction as
follows
1:AT+HOSTEN3 / / configured transparent transmission mode
2: AT+ CLSSE0 / / iBeacon type configuration
3: send AT+RST / reset
You configure the iBeacon device type through the 3 steps above

Description: the factory default for AT+CLSSA0 type, this function is to pass through
common functions, such as the user of the product safety requirements are very
high, beware of other people use APP to modify the parameters can modify the
module (broadcast, broadcast interval, interval connection etc.), users can consider
using the AT+CLSSA2 model, some model of APP configuration parameters (no
response radio, radio, etc.), the connection interval interval of these parameters
can only be modified by AT instruction.
If the user MCU pins not much data, do not want to use MCU to determine the Bluetooth
connection status, you can consider using the AT+CLSSA1 mode, in this mode,
when a Bluetooth connected or disconnected from the serial output module, status
information to the user MCU
