900mhz Does not work #3

Closed Crypt0s closed 10 years ago

Crypt0s commented 10 years ago

The 802.15.4 layer doesn't appear to support 900Mhz Zigbee.

Could we get a version that does support 900Mhz or could you indicate what needs to be changed in order to support 900Mhz operation?

bastibl commented 10 years ago

The 15.4 standard defines a lot of different PHYs. These blocks implement just the O-QPSK PHY for 2.4GHz operation. If you want to use O-QPSK on 900MHz you will have to make some straightforward changes (chip mapping, etc.). You can find the details in Chapter 10 of the 15.4 standards document. I have no hardware that operates on those frequencies and thus, could not implement and test this stuff. You are of course more than welcome to add support for 900MHz.

Thanks I will. I Have some questions -- could you drop me a line? bryanhalf@gmail.com?

@Crypt0s @bastibl

Was this ever added? I would like to use this library with an RTLSDR to listen to 868Mhz Zigbee. I assume the issue for 900Mhz are similar or the same as those for 868Mhz.

In advance thanks

I'm not aware of an extension for 868/900 MHz.

Thank you for the quick reply.
