Sub-GHz RF P2P+ Module

Product ID.：WL32XS

Communication mode： UART(Local), RF(Remote)

WL32XS module can be set as DN (Distributed Node) in fast wireless data transmission P2P+ application network, connect and collocate with terminal devices linked to the micro-power network, and finish data pass-through and collection. It can also set as UN (User Node) so as to realize customer device’s self-recognition, one-key collection and synchronization of surrounding terminal facilities. Applicable to AMR/AMI/IoT, it offers best solution for low power consumption, low cost, high efficient, and long distance communication.

  • Main Functions
  • Technical Parameters
  • Anti-interference function. Use low noise, high receiver sensitivity and advanced data encryption technology. High anti-interference function, high communication rate;
  • Wireless communication environment analysis function. Inquire RSSI of communication link between nodes through directive to check current communication quality;
  • Support P2P+ application. User device can self-discover, one-key collect and synchronize surrounding terminal facilities without knowing the facility quantity and ID;
  • Flexible role configuration. Support DN or UN configuration;
  • Event report function. Automatically send data to CN/UN when working as DN;
  • Local communication parameter self-adaptation. Support local communication baud rate and handshaking self-adaptation.
