For iOS devices, it is recommended to use Lightblue or nRF Connect. For Android, you can use the Shenyun Universal Android Test App, which can be acquired by contacting their support team.
The default serial port baud rate is typically set to 9600 bps, configured with 8 data bits, 1 stop bit, and no parity.
You can change the broadcast name by running the AT command "AT+NAME=". For certain AT commands, a module restart may be required for the settings to take effect.
If the serial port package exactly matches the threshold (e.g., 20 bytes), the module immediately sends it via Bluetooth. If it is less than the threshold and the serial port data remains empty for more than 10ms, the module automatically forwards it to the app.
