In trying to verify that all functionality is working in the 4.x stack, I found bluetooth-sendto to be fairly broken. You can't use it with a release version of ODS because the release version only supports 3.x. The SVN head version changed APIs though for the 4.x stuff, and expects different behavior.
The attached patch makes it work with SVN head of ODS. This should be used in conjunction with Bastien's patch.
