N        This expression returns the 32-bit memory address of the binary to send.

The binary to send always has a valid address, and starts out as 0 bytes long.

This address can be used in conjunction with extensions like Binary Quickload and the Memory Object for quickly filling the binary to send with data.

Android/iOS/Mac warning

In Blue Client Android/iOS/Mac, on 64-bit devices, this expression will return a 64-bit address by cropping to 32-bit, which may be invalid and cause a crash.

HTML5/UWP warning

This expression will not work in Blue Client HTML5/UWP; it will create an error and return blank.

To access the binary-to-send message in HTML5/UWP, you can use:

read: client['GetSendMsg']() – will return a Uint8Array

write: client['SetSendMsg'](Uint8Array)
