Example:
Send: AT+CONT=1
Return: OK
Setup is complete, effective after module automatically reset!
Send: AT+CONT=?
Return: Non-Connectable
The command please with "AT+MODE", "AT+AVDA" and "AT+AINT" command with
the use of.
Note:
1. The master/slave module “CONT=1” is masterly used for transmitting broadcast
data. From the slave role to send broadcast data, broadcast master module will receive
the corresponding data, and through the serial port output.
2. This model is only for the user can grab this broadcast data package yourself.
The specific communication protocol is not described here, the intention to please the
following official website consultation online customer service: http://www.hc01.com/
⑫ Change the broadcast data（Only slave module）
Command: AT+AVDA=xxxxxxxxxxxx
Parameter “xxxxxxxxxxxx” can be any 1~12 bytes user data. If at this point the
master module state of AT+CONT=1, then the master module UART port will output the
“xxxxxxxxxxxx” data. The broadcast data will not be preserved permanently, will be
deleted after the restart.
Example:
Slave role send: AT+AVDA=1234567890AB
Return: OK
If at this point the master module state of AT+CONT=1, UART port will output:
1234567890AB.
⑬ Set working mode（Only slaver）
Set command: AT+MODE=x
Query command: AT+MODE=?
Command Parameter Return Function
=? 0/1/2 Gets the current mode.
=0 Full power mode (default), LED open.
=1
Level 1 power saving mode, LED close.
The connection current is determined by the setting
of AT+AINT. The connection is mainly determined
by AT+CINT. The MODE1 has covered the 2.4
version of MODE3 and is more reasonable.
AT+
MODE
=2
OK
Level 2 power saving mode, LED close.
No connection the current is 0.4μA.
Can not be found, not connected before wake up,
after awakening can be connected.
