hi shafiq,
your questions will be better serviced is addressed to shimmer research
support ([email protected]). this mailing list is geared
toward application development questions and discussion.
i will say that your application does not wire to nor call the bluetooth
module's init routine, so it will never respond to incoming traffic.
but first i would find out why you can't seem to power the shimmer off.
suggestion one: start with blink. suggestion two: install
boilerplate and run the shimmerconnect app to see if well-tested code
works properly.

Hi,
Whenever I charged my shimmer node for the first time, I saw RED led is
on. Then, I tried to press the reset button for 10 sec to shut it down.
But, it never goes off. RED and orange light is always on. Then I tried
to program the node with a sample application. It programed
successfully. But RED and orange light is always on. Finally I tried to
pair with my laptop using blue-tooth. My laptop can detect the node and
can connect successfully by assigning the node as "FireFly-DE7D".
Later, I installed the HelloWorld program on node but did not get string
on my HyperTerminal instead got "$$$". I have attached the screen shot.
Finally I tried to detect the node using my nokia N97 mobile. But, my
mobile never detected the node.
Could you please tell me how can I resolve these issues?
Regards
Shafiq
