Description of APP instructions (IO, password)

9.1: Password Settings
Format: AABBE551 + 4Byte native password + 4Byte new password //hexadecimal format The new password can be set only if the local password is the same as the module password.
9.2: APP password sent
Format: AABBE552 + 4Byte APP password //hexadecimal format
When AT+ISCEN1 is turned on, it means that the APP password is used. After each connection, the APP will send a password to the module. After the password is correct,  the APP can control the module’s IO or transparent transmission (the module default APP password is off).

9.3: APP Control Module IO Level (Feature UUID: FFE1)

Command Output Level
IO1 AABBE7F101 IO1 is set to high
AABBE7F100 IO1 is set low
IO2 AABBE7F201 IO2 is set to high
AABBE7F200 IO2 is set low
IO3 AABBE7F301 IO3 is set to high
AABBE7F300 IO3 is set low
IO4 AABBE7F401 IO4 is set to high
AABBE7F400 IO4 is set low

Note: The data format is in hexadecimal format.

9.4: Transparent transmission UUID
Service UUID: FFE0
Feature UUID: FFE1 attribute (WRITE, NOTIFY)
