Hi Guys,
The Photon should be able to send data to Ubidots without a problem. Looking at their example, I see something funny that could be a problem on this line:
request.path = "/api/v1.6/variables/"VARIABLE_ID"/values";
Since the VARIABLE_ID that #define'ed above already has quotes, this looks wrong to me. Can you try something more like this:
request.path = "/api/v1.6/variables/7lIgBfvGWdCh56j1bcunhfnYrMPLJh1/values";
Where the variable ID from the sample above is replaced by your actual variable ID.
