2) When masters and slaves enter this mode, its scanning and broadcasting function remain unaffected.

5.2 Wake-up mode

In any case, WKP (P06) or serial RX pin (selectable command <COMWKPON> configuration to enable serial port wake-up)

input falling edge, the module wakes up from low power mode, if the command <WSMON> turns on mode feedback, wake up The

serial port will automatically output WAKEUP to notify the user that the wake-up operation is successful. From the detection of the

falling edge to the completion of the module wake-up for about 7 ms, the transparent transmission function is temporarily disabled

until the system wakes up successfully and the system returns to normal.

In wake-up mode, the module enters configuration mode via pulling down Pin P00 and now any data received by the module is

regarded as configuration instructions rather than for transparent data transmission, that is, the transparent transmission function is

invalid.

Description:

1) Any data transmitted by the master via Bluetooth channel "CENTER DATA BUFF" is not for transparent transmission if

Bluetooth is connected now, and channel "BLE DATA BUFF" will receive feedback information "<CONFIG MODE BUSY>"to

indicate that the slave is in configuration mode and doesn't receive data via transparent transmission.

2) In configuration mode, all configured information for the module will be saved after powering down and it will operate

according to the new configuration when powering up next time.

Bluetooth outputs transparent transmission via serial port when receiving data. To ensure correct receiving of external MCU, at

10 ms before UART outputs the first start bit, P03 (APP) pulls down and wakes up external MCU till data transmission is completed

and P03 recovers a high level.. As shown in the figure:

Description: 1) The data output valid function can be commanded to turn on or off with <APPON>/<APPOFF>.

The module can be configured as a master or a slave. In 160ms after powering up it starts to read the level signal of Pin P14. If a

low level signal is detected the module will be configured as the master; if a high level signal is detected it will be the slave; if the pin

floats, module with internal pull-up resistance will act as a slave. Role configuration is only valid when the module is powered up and
