Software

Within the neuron program you can influence the behaviour of the node by setting different flags

Flags:

  • 0 : Test: By connecting the Serial node to a terminal on the PC it's possible to test the node. To do so, configure the terminal with following settings:
    • Baud: 9600
    • 8 Data bits
    • 1 stop bit
    • No parity
    • No handshaking (flow control)
    • Send the product number followed by 0x0D. (ex. 5$0D --> product 5 is send)
  • 1 : CSI Schearer protocol
  • 4 : Leopard valve - RF Controller (only supported in sernodes with firmware v1.7 and up)
