Thanks for reminding me about google. I am trying with C++ and cannot go for other languages due to Project restriction.
Since i have a lot of data accumulated in my Node and TTN right now has no implementation for deletion. I have to somehow parse the data to my needs. I am able to read the data perfectly on the TTN example node:
http://thethingsnetwork.org/api/v0/
however the data on my node is populated in a different way and I am still on look for getting it parsed correctly.
