    The maximum length of the registration packet is 40 bytes (when set to HEX format, the maximum length is 20 bytes). c) Heartbeat packet: In the idle state of network communication, the heartbeat packet is used for network state Copyright ©2012–2019, Chengdu Ebyte Electronic Technology Co.,Ltd.
  • Page 10 After the AT+EBTIOT command is used to set whether the module will enable the transparent transmission function of the Ebyte cloud platform, after the device is turned on, the information such as the heartbeat and registration packet configured by the user will be invalid. The user only needs to set the forwarding relationship of the corresponding device to the platform to implement the device.
