Nilesh, It appears that you have not read through many of the tutorials or tried out the sample applications. There are numerous problems with your code, but I'll highlight a few here: 1) You should always access components through their configuration, not their module. Thus you should use

1) without your code, it is impossible to debug 2) are you using uint8_t fields or uint16_t fields? if you assign a uint8_t to 0x, you will only get 0x00 out from the serial port. 3) have you tried sending real data through the tinyos tools instead of implementing your own (potentially

You need to use tinyos-1.x/apps/CntToLedsAndRfm and tinyos-1.x/apps/RfmToLeds. Do not use the Xbow version, it has not been updated for cross-platform communication with Telos. -Joe On 11/3/05, Thiagraj Peri Natraj [EMAIL PROTECTED] wrote: Hi, Is it possible to run CntToLedsAndRfm in Telos

2005-10-26 Thread Joe Polastre
LQI is a measure of the *error* in the signal, not the strength of the signal. A weak signal may still be a very crisp signal with no errors (and thus a potentially good routing neighbor) If there is no interference, other 2.4ghz devices, etc, then LQI will generally be good over distance.
