New RF board (Sub-GHz)

We assembled two CC1101 RF boards.It took me a few days to get the the board working with the  MSP430G2955 controller board. I configured the CC1101 to operate at 866 MHz which is license free in India. I was able to do some range testing and I am really happy with the performance of the C1101. The range is far more than the CC2520 which operates at 2.4 GHz. I have added some pics of the module below. We will be adding this board to our store in a month or so. I still have bunch of things to do (including testing the C1101’s low power mode). I will also be doing extensive range testing – both line of sight and through walls.

The associated MAC still looks like 802.15.4. The CC1101 does not support automatic acks like the CC2520. I have modified the MAC code to send ACK when requested by the originator.

Here are some pics.

    Nice to see the new module. It will suit applications that need the longer range and can live with bigger antennas.
