Re: [Tinyos-help] Getting temperature using Ppp Router and CoapBlip
Hello again, I have debugged the program. Fortunately it is a C based client and I can use GDB. However what I see is that data from the pdu is coming back empty, “0”. How can I know that I am sending the proper request?. I see different choices depending on the versión of CoAP. Any idea on that?. I am using this: coap-client -m get coap://[fec0::2]:61616/sen/temp -T 3a -t binary but I took it directly from the examples, I don’t know what those options mean. I can’t find the meaning anywhere. Any idea on that?. Thanks.

You can clearly talk to it. Either way you need to understand what the remote mote is doing.

Re: [Tinyos-help] Getting temperature using Ppp Router and CoapBlip
The remote mote is essentially a block box that is very hard to gain visibility into. the way I deal with this kind of problem is either: 1) put a debugger on the remote mode, set a break point where it does the command processing, capture receiving the command. this will let you bifurcate the problem. or 2) instrument the remote tag so you can grab information from it. You can clearly talk to it. Either way you need to understand what the remote mote is doing.
