The WSN1101CL is a low profile WiSense wireless mesh coordinator node. It includes the CC1101 high performance sub-ghz radio (from TI) and the MSP430G2955 micro-controller (from TI).

Node dimensions: 42 mm x 42  mm x  10 mm

The radio board has a U.FL antenna connector. We provide multiple antenna  options. 

  • Whip antenna which can directly connect to the U.FL  connector on the radio board
  • Half-wave  dipole  3  dbi  antenna  with  SMA  connector. Use  a U.FL to SMA bulkhead RF cable assembly to connect the radio board to the antenna.

The WSN1101CL comprises of two PCBs. One PCB hosts the micro-controller while the other hosts the CC1101 radio. The micro board has a 128 Kilo-Byte serial EEPROM which can hold two complete firmware images. It also has another 256 byte EEPROM  which also provides a hardwired and globally unique 64 bit MAC addresses.  

The  WSN1101CL  has  an on-board  USB Mini-B port which can be  used  to connect to a laptop or Linux SBC such as  the Raspberry PI. The USB  Mini-B port provides power and  serial connectivity.

The WSN1101CL comes pre-programmed out of the box to operate as a WiSense mesh network coordinator node operating in the 865-867 MHz license free band (in India). The network raw baud rate is 1200 bps. Max output power is +10 dBm. Receiver sensitivity @ 1200 bps and 1 % PER is around -110 dBm.

The coordinator node is responsible for setting up and maintaining a single instance of  a  WiSense  LPWMN (low power wireless mesh network). It allocates a unique 16 bit address to each node which  joins the network.  It also serves as  the gateway for the entire network. All communication between the nodes in the  network and the outside world happens through the coordinator node. 

WiSense provides a Linux/Cygwin based CLI to configure and query the WSN1101CL and associated  LPWMN (low power wireless mesh network).

The  Linux/Cygwin based CLI can be used (for example) to:

  • Set the RF channel (channel 1 to  channel  9) on which the LPWMN will  operate.
  • Set the 16 bit LPWMN  identifier (LPWMN Id).
  • List all the nodes in the network.
  • Get/Set attributes on the Coordinator and other nodes in the network.
  • Request the  coordinator to reboot itself.
  • Request any node in the network to reboot.
  • Upgrade the  firmware running on the Coordinator.
  • Upgrade the firmware on any node in the network (over the air upgrade).
  • Get information on the version of firmware running on the coordinator or any other node  in  the LPWMN.
  • Monitor sensor data messages received from any node in the network
