driven by external MCU, use the push output control.
Same to 1。

Application
Ground
GPIO/PWM Can be configured as GPIO
input/output or PWM, see
GPIO/PWM section 6.9 GPIO Features for
Low level：configuration
Mode selection
High level：transparent mode
Wake up：falling edge；
Wake up pin
Sleep：rising edge。
Connection pin Internal pull up. Valid in
disconnected
Ble link：low level
Link status
No ble link：high level
Data indication pin,
the module outputs data
through the serial port, the
module sets the data pin to
Data indicator low level, indicating that data
is being sent. The at
instruction response does not
change the state of the data
