The invention discloses a communication method and device, a storage medium, a voice board, a checker board, and an air-conditioner. The communication method of the voice board comprises the followingsteps: acquiring address information of an individual communication module of the checker board and identity information of a mainboard through a mainboard serial port of the air-conditioner after avoice communication module of the voice board is powered on; sending a broadcast packet to the individual communication module based on the address information and identity information; analyzing a broadcast response packet after receiving the broadcast response packet returned by the individual communication module based on the broadcast packet; if the analysis is successful, establishing the communication connection between the voice communication module and the individual communication module, thereby establishing a local area network between the voice communication module and the individual communication module. Through the scheme disclosed by the invention, the problem that the communication is inconvenient since the voice module and the WiFi module cannot directly communicate and themainboard is required for forwarding the information is solved, and the effect of improving the communication convenience is improved.
