RFM2Pi

======

RFM2Pi full support for RFM69

• I replaced original RFM2Pi firmware that uses JeeLib with RMF69 library. Source code
• Compiled firmware
• Sample output

Features

[RF69demo.13] @ i0 g0 @ 868 MHz

Available commands:
  <nn> i     - set node ID (standard node ids are 1..30)
  <n> b      - set MHz band (4 = 433, 8 = 868, 9 = 915)
  <nnnn> o   - change frequency offset within the band (default 1600)
               96..3903 is the range supported by the RFM12B
  <nnn> g    - set network group (RFM12 only allows 212, 0 = any)
  <n> c      - set collect mode (advanced, normally 0)
  t          - broadcast max-size test packet, request ack
  l          - show led activity
  ...,<nn> a - send data packet to node <nn>, request ack
  ...,<nn> s - send data packet to node <nn>, no ack
  ...,<nn> r - send ACK reply data packet to node <nn>
  ...,<nn> w - preddefined ACK reply data packet to node <nn>
  <n> q      - set quiet mode (1 = don't report bad packets)
  <n> x      - set reporting format (0: decimal, 1: hex, 2: hex+ascii)
  <nnn> y    - enable signal strength trace mode, default:0 (disabled)
               sample interval <nnn> secs/100 (0.01s-2.5s) eg 10y=0.1s
  <nn> j     - sends local temperatur to node j
             - if j>256 it displays temperatur in 1min time frames
  u          - upload firmware using FOTA/Wireless programming
  m          - dumps registers
  ... n      - set encryption key, consists of 16 numbers, 
             - if less than 16 number provided they are padded by zeros
             - 0n mean disable encryption
             - 1,2,3n -> 1,2,3,0,0,0,0,0,0,0,0,0,0,0,0,0
  <n> p      - promiscuite mode 0 off, 1 on
  v          - display version and configuration
  h          - display help
  123 z      - total power down, needs a reset to start up again
Current configuration:
 @ i0 g0 @ 868 MHz

• 1,2,3,0,0,0,0,0,0,0,0,0,0,0,0,0n command to set an encryption key.
• I have some support for FOTA but it is not streamlied version because I stole some stuff from Wireless programming library.

Current version of firmware is not compatible with latest RFM69, I use a custom version https://github.com/vvvlc/RFM69, https://github.com/vvvlc/WirelessProgramming

RFM12B / RFM69CW to Raspberry Pi board

With the addition of an RFM12Pi expansion board to receive data via wireless from other OpenEnergyMonitor modules such as an emonTx energy and temperature monitoring node or an emonGLCD display. A Raspberry Pi used to forward data to an emoncms sever or/and log data locally to a localy instance of Emoncms server running on the Pi.
