Hi Ravi, Thanks very much for that. I'll try it now. Looking briefly at the code, I think the key may be the use of the interface SplitControl, which I wasn't aware of before. I think that should be a better way of handling turning the radio on and off. Once I've played around, I'll post my f

Well, I've had some success. Basically I've used SplitControl to wire directly to CC2420RadioC (whilst keeping all the GenericComm stuff in place to handle the messages). Then I use this type of thing: event result_t Timer.fired() { SPACER = !SPACER; if (!RADIO_ON && !SPACER) { call L

[Tinyos-help] About Sensitivity and RSSI.

Hello everyone. In CC2420 data sheet. it specifies the high sensitivity (-95dBm). Received power in cc2420 can be drived from RSSI value. (P = RSSI + Offset (-45dB)) The minimum RSSI value was -49dBm in my experiment. Therefore received power -94dBm was the minimum power in Tmote Sky. Can i co

Re: [Tinyos-help] About Sensitivity and RSSI.

2007-02-07 Thread Robert Szewczyk
Yes, you can compare these powers directly. The sensitivity threshold is -95 dBm, and consequently CC2420 will not report RSSI below that threshold. The RSSI reported is the absolute measure of the energy in the incoming signal; you can access RSSI when there is no packet being received, and the

Thanks you for your advices. We want to derive a accurate SINR of incoming packet. Then, can i understand that received signal power in cc2420 data sheet means the SINR of incoming packet? It seems after we consider the offset value (-45dB) it provides the SINR from RSSI value. Moreover, if we st
