For SDK 2.0.1 on the BCM20736S, is there a hard limit to the number of, or total number of bytes in, prepare write requests accepted before an execute write request?

thanks, Stuart

WICED SDK 2.0 supports characteristics of up to 23 octets in length.  2.1 (should come out within few weeks) out of the box supports characteristics of up to 256 octets in length.  All operations (read, read blob, write, reliable write, ...) are supported.  With additional patch you can support prepare write of up to 512 bytes or more.  Please note that all RAM is shared between the stack and the application.  So if you need 2 buffers of 512bytes, memory available for your application will be 1K smaller.
