915 rather than 868MHz

turns out the 868MHz band is restricted in Australia (used for mobile phone networks), would it be possible to swap the module for one of these:

Second that request.

The 868MHz band is not available to Australian or US users, but the 915MHz band is. Jeenodes shipped to non-European addresses are equipped with RFM12B modules with frequencies matched to the destination. Does Flukso do the same with the FLM02B hardware?

David Rowe, a distributor in Australia, only has the FLM02A hardware in stock (email as of 13 Feb).

Please explain the reason for this?
Mine works ok..I think?

hi baz, what do you mean by "works"? the issue is we're not actually permitted to use devices in the 868MHz band (because telstra use it for mobile phones) in Australia.

So does that mean the wifi side of the Flukso is illegal now in Oz ?
(Not that I will be turning mine off, I doubt the weak local signal will affect anything?)

no. this isn't about the wifi, it's about the new feature on the v2b:

"A 868MHz radio module is included on the sensor board. This RFM12B module is identical to the one used on the Jeenode. The driver on the FLM02B even speaks the Jeenode protocol, opening up a world of possibilities to extend the Fluksometer with a range of wireless sensors like temperature, humidity, movement detection. Because the full coupling between wireless sensors and Flukso back-end hasn't yet been completed, this feature is still tagged as experimental."

Thanks for the explanation. I'm sure others will appreciate it too ;)

The RFM12B's receiver on the FLM02B can be reconfigured to communicate on the 915MHz band. The analog front-end should work equally well in 915 as in 868. So it's basically a matter of making this center frequency configurable via the local web interface in a future firmware release.

Thanks for the confirmation.

Can the radio module be disabled/turned off or is it off by default? If so, I'll order one today and re-enable the radio module after the firmware update.

The radio module is currently configured in Rx mode. Since no software is triggering a packet transmission, it never switches over to Tx mode. It's a passive listener for the time being.
