Re: [Discuss-gnuradio] Issue Receiving Messages Using Gr-IEEE-802-15-4

Hi,

great you got it working. AFAIK, there is not *the* XBee module, but
very different modules are sold as XBee. Some of them support standard
compliant IEEE 802.15.4/ZigBee (O-QPSK in 2.4GHz). They will work with
the OOT.

Best,
Bastian
