/** @brief Object write callback
*
* This callback is called multiple times during the Object write
* operation. OTS module will keep providing successive Object
* fragments to the application until the write operation is
* completed. The offset and length of each write fragment is
* validated by the OTS module to be within the allocated size
* of the object. The remaining length indicates data length
* remaining to be written and will decrease each write iteration
* until it reaches 0 in the last write fragment.
*
* @param ots OTS instance.
* @param conn The connection that wrote object.
* @param id Object ID.
* @param data Next chunk of data to be written.
* @param len Length of the current chunk of data in the buffer.
* @param offset Object data offset.
* @param rem Remaining length in the write operation.
*
* @return Number of bytes written in case of success, if the number
* of bytes written does not match len, -EIO is returned to
* the L2CAP layer.
* @return A negative value in case of an error.
* @return -EINPROGRESS has a special meaning and is unsupported at
* the moment. It should not be returned.
