CC1100E: Channel interference issue in Simpliciti

Part Number: CC1100E
Other Parts Discussed in Thread: SIMPLICITI, CC1100

Hi,

We are using the SimpliciTi protocol in Gateway - Node mode using cc1100(433 MHz) and MSP430.

There are 2 set of device, one communicating in channel 0 and other in 1.  Channel is set using the API MRFI_SetLogicalChannel() in the file mrfi_radio.c

While testing we could find data from one board set is being transmitted to another set even though they are separate channels.  ie it seems like some RF interference has occured.

Is there a chance for this?  Has any similar issue been reported ?    Please advise how to debug this

    I don't know SimpliciTI too well but this sounds like a fundamental RF issue, not a stack issue.

    How large Rx Bw do you use and what is the channel spacing?

    If you use a strong signal in your testing some of the signal will go into the next channel. Then you will be able to receive it. If you send on channel 1, what is the RSSI receiving on channel 0 and 1?
