HLK-B10 USER MANUAL 4. Basic Functional Description 4.1. Two working states of the module HLK-B10 module has two working states: transmission mode and AT command mode. In AT command mode, the command can be sent to the module through serial port to configure the parameters of the module and query the information of the module. In transmission mode, the module will transmit the serial port data and Bluetooth connection data in two-way.
HLK-B10 USER MANUAL mode; Long press(More than 6s),release the button when the status LED starts flashing, the module will restore the default settings, and automatically restart. 4.3. Switching Between Transmission and AT Command Mode 4.3.1. From transmission mode to AT command mode There are two ways to switch the transmission to AT command mode: key mode: Pull down the fifth pin 50ms~1s,The module immediately enters the AT command mode.
HLK-B10 USER MANUAL 5. AT command 5.1. AT command format Format the class command:AT+=<...> X represents the name of the parameter to set,…represent Parameter Value Set a successful return value: Set return value for failure or format error: AT+=<...> OK AT+=<...> ERROR example: send out:AT+DEVNAME=HLK-B10 received:AT+DEVNAME=HLK-B10 OK Query class command format:AT+=? x represents parameter name of the query,… represent parameter value。 Returned value : AT+=? <...
