⑮ Change the connection interval
Set command:AT+CINT=xx,yy
Query command:AT+CINT=?
Connection intervals affect the power loss of connection, the master needs to be set
at the same time.
In this command, xx is minimum connection interval, yy is maximum connection
interval. xx≤actual connection interval≤yy. A single parameter xx can be entered
separately, if the yy < xx is recorded, at this time, yy will be replaced by xx.
Each time unit of the broadcast interval is 1.25ms, the setting range is 6~3199
(equal to 7.5ms~4s)
Example:
Send: AT+CINT=80
Return: OK+ CINT=80, 80
Connection interval modified 100ms.
Send: AT+CINT=6, 12
Return: OK+ CINT=6, 12
Connection interval modified 7.5~15ms.
Send: AT+CINT=?
Return: OK+ CINT=6, 12
Connection interval is 7.5~15ms.
⑯ Change the connection timeout time
Set command: AT+CTOUT=xx
Query command: AT+CTOUT=?
Each time unit of the connection timeout time is 10ms. The unit range of the
connection timeout time is 10~3200 (equal to 100ms~32s).
This value directly affects the time of disconnection, the time of "accidental
disconnection" (active disconnection is not affected by this value).
Example:
Send: AT+ CTOUT=200
Return: OK+ CTOUT=200
Connection timeout time modified 2s.
Send: AT+ CTOUT=?
Return: OK+ CTOUT=200
Connection timeout time is 2s.
⑰ The master module to clear the slave module address have been recorded
（Only master）
Set command: AT+CLEAR
Query command: OK
