Remarks
- Generally communicate with APP connection, it suggests broadcast should not be set too long, which will affect the connection time. It is generally recommended between 100 to 500ms, and if you need to connect fast and no power requirements, broadcast intervals can be set to the shortest.
- Under connection state, the AT command can be pulled down by PWRC pin or the working mode is set directly, please see the AT+STARTEN instructions
AT instruction: AT+STARTEN
-
Mode 0 Wake up, users need sleep can be controlled by AT+SLEEP command, wake up can be controlled by PWRC pin wake-up.
-
Mode 1 Boot sleep, wake up after the connection, disconnect automatically into sleep. Note: AT+SLEEP invalid mode 1, sleep controls sleep by Bluetooth module itself.
-
Mode 2 Boot sleep, connect and disconnect all sleep, APP to send data to the serial port module or module to send data automatic wake-up, after data transmission is completed, it will be automatic sleep. Note: AT+SLEEP of mode 1 is invalid. Note: AT+SLEEP invalid mode 1, sleep controls sleep by Bluetooth module itself.
- How does MCU disconnect Bluetooth connection under connection state? In the connection state, the PWRC pin is pulled down, and the serial port sends AT+DISC to disconnect the connection IIC can disconnect the memory address: 0x15 writes 0x01 values to indicate disconnection
- Can it write data to the module if the connection password is incorrect? No, it can’t. Only the correct password can write data to the module
- How much data can the serial port write at one time? No byte limit, 100k can be sent once (master-slave communication)
- How fast can the fastest communication rate be reached? With mobile phone measured 8K Bytes per second, module master slave communication can achieve 115200 baud rate continuous transceiver, and the rate of 115200bps.
- After configuring parameters by serial port or IIC, does it need to be restarted to take effect? It is recommended to restart when the module parameters are set.
- Parameters of serial port or IIC configuration, is the power up stored next time? After saving, configuring, the next power up is the last configuration parameter.
- How to test the deep sleep current of test module? It is recommended to connect the VCC and GND pins to test current.
