[timgates42]

There is a small typo in core/liblwm2m.h.

Should read bootstrap rather than boostrap.

@timgates42 something went wrong with the eca signing

Anonymous (tim.gates@****.com) is not covered by the necessary legal agreements in order to proceed.

Make sure your eclipse account use the right e-mail and that the "eca" is signed. Repeat steps above to retrigger test...
