I'm cc'ing this back to the help list where someone may be able to...
From this is seems that your sensor is not working, perhaps not wired
or powered correctly. But I would first start with a simple radio
message transmission, like CntToRfm, to make sure that you have
connectivity. Then I would review all the connection issues with
your sensor. Without all the specs and schematics I can't help more.

Dear Michael:
Thank you so much for your answer.
I tried again. And that error disappears.
Currently, I am using Micro Power Oximeter Board 31392B1. I attached one mica2 to the Micro Power Oximeter Board 31392B1. And Micro Power Oximeter Board 31392B1 was connected to a 1300 Single Patient Adult Sensor, which is used to collect the data of heart pressure and so on.
I have attached some photo to show the situation.
I have uploaded the program to this mica2 using MIB510. When I turned on the
switch of mica2(433MHZ), the light in 1300 Single Patient Adult Sensor can't
be turned on. Normally, the light should be on, so that it can collect the
heart pressure data.
On the other side, another mica2 is connected to the MIB510 board, the MIB510
is connected to a desktop, which can show up the data collected by the mica2.
After I entered the command
java
net.tinyos.tools.Listen
the light on the mica2 attached to the MIB510 keep on flashing. But there is no
input signal as the 1300 Single Patient Adult Sensor doesn't work.
The result on the screen turns out to be like this:
$ java net.tinyos.tools.Listen
test
[EMAIL PROTECTED]:57600: resynchronising
And nothing happened next. Normally, a window should pop up showing the real
time
data collected by the other mica2.
I have attached some photos showing what is the situation. Please have a look
at it.
I really appreciate if you can give me some advice about that.
Thank you so much!
Sincerely,
Bo Xu
