Hi there,
Thanks for your updating.
Hans, thanks for the more clear orgnization of the google code structure.
rich, the antenna lenght of RFBee is for 915MHz,(λ/4). If working 868 or 433 longer antenna may get the best effect. BTW, the hardware design of RFBee is not for 433 or 315 (refer to the datasheet of cc1101), so it may not work in these two bands.
All the best,
