Martin<\/a> has been creating awesome little funkys based off of the jeenode boards. I picked up a couple v3’s with the newish rfm69 chips<\/a> to try out their improved range and power consumption. After getting some help from Matt, we were able to have them talking to each other. Sensor A ran a version of the TimedSend example sketch while sensor B ran the rf12demo sketch found on Martin’s website.<\/p>\n

Sensor A configuration: nodeId: 1, band: 433Mhz, group: 212
\nSensor B configuration: nodeId: 17, band: 433Mhz, group: 212<\/p>\n

To configure sensor B, we typed into the serial monitor: 4b 212g 17i<\/p>\n

Available commands w\/demo sketch:
\ni – set node ID (standard node ids are 1..30)
\nb – set MHz band (4 = 433, 8 = 868, 9 = 915)
\no – change frequency offset within the band (default 1600) 96..3903 is the range supported by the RFM12B
\ng – set network group (RFM12 only allows 212, 0 = any)
\nc – set collect mode (advanced, normally 0)
\nt – broadcast max-size test packet, request ack
\n…, a – send data packet to node , request ack
\n…, s – send data packet to node , no ack
\nq – set quiet mode (1 = don’t report bad packets)
\nx – set reporting format (0: decimal, 1: hex, 2: hex+ascii)
\n123 z – total power down, needs a reset to start up again<\/p>\n

Remote control commands:
\n,,, f – FS20 command (868 MHz)
\n,, k – KAKU command (433 MHz)<\/p>\n
