<on-off>: It means opening or closing socket 0, 1 means open, 0 means closed.

Note: When power-off saving is required, input AT+NRB command will save the parameters to the flash, and the

automatic restart will take effect.

3.11 Heartbeat packet function configuration

3.11.1 Configure TCP/UDP heartbeat packet content

AT command

Response

AT+HEARTINFO=<type>,<data>\r\n

AT+HEARTINFO \r\n

<data>

<type>: 0 indicates that the heartbeat packet type is in HEX format, and 1 indicates that the heartbeat type is in ASCII

code (string) format.

<data>: The data content of the heartbeat packet, the maximum length is less than 40, and the default value is "Ebyte

nbiot heart rate data".

Note: When power-off saving is required, input AT+NRB command will save the parameters to the flash, and the

automatic restart will take effect.

3.11.2 Send heartbeat packet command

AT command

Response

AT+SENDHEART=<send>\r\n

(1) Input AT command AT+SENDHEART=1, then the heartbeat packet can be sent.

(2) If <pdu_type> is selected as TCP/UDP, the TCP/UDP heartbeat packet will be sent, if it is MQTT, the MQTT

heartbeat packet will be sent ("PINGRESP" will be printed on the serial port after successful transmission), and if it is

Ebyte Cloud, the Ebyte Cloud heartbeat packet will be sent.

3.11.3 Heartbeat packet mode and heartbeat cycle configuration

AT command

Response

AT+HEARTMOD=<mode>,<period>\r\n

(1) This command is used to realize the function of sending heartbeat packets periodically. The function of sending

heartbeat periodically is mainly used in DTU function scenarios (no low power consumption requird). To set the

periodic heartbeat function, you first need to set AT+DTUUSER=1 and AT+NRB to save after power-off, that is, the
