The RFM69Pi is a minor update to the popular RFM12Pi Raspberry Pi Expansion board. It adds support for the RFM69CW RF module as well as breaking out as much I/O as possible from the ATmega328 to open up the options for greater connectivity and compatibility. The RFM69Pi was developed with help and inspiration from Nanode RF designer Ken Boak, together we are working on a relay heating controller board using the RFM69Pi.
The RFM69CW is backward compatible with RFM12B, see blog post introducing the module. From an end user's perspective there should be no difference when using the RFM69Pi over the RF12Pi apart from a new input called RSSI (Received Signal Strength Indication) appearing in Emoncms.
emonHub must be updated to the latest Development branch version to enabled auto detection of the faster baud rate used by the RFM69Pi (38400 as opposed to 9600 on the RFM12Pi), and RSSI value handling.
If you're running pre-built SD card image (emonSD-13-08-14.img or earlier) then emonHub can be updated by running:
$ sudo service emonhub stop
$ cd emonhub
$ git pull
$ sudo service emonhub start
check log for errors
$ tail /var/log/emonhub/emonhub.log
The RFM69Pi is now shipping by default instead of the RFM12Pi from our online shop
