CurieBLE: Discover attributes fails with macOS + bleno test.js app

[sandeepmistry]

When I run the peripheral explorer example against my macOS 10.12.3 Mac running the test.js example of bleno, the attribute discovery fails. Testing against Raspberry Pi is fine.

Attribute discovery failed!

I've attached a screenshot of the PacketLogger app:

This seems to be a duplicate of #373.

If I remove the last 2 characteristics the bleno test.js app adds, things are fine:

	Characteristic ffffffff-ffff-ffff-ffff-fffffffffff4, properties 0x12

Note the ffffffff-ffff-ffff-ffff-fffffffffff4 and ffffffff-ffff-ffff-ffff-fffffffffff5 characteristics from the origin test.js file have been removed.

So, it appears to be a memory limitation.

I believe this issue should be addressed with Deneb.

@SidLeung this still happens with Deneb:

I believe it is memory related and with be resolved in Bootes.

This looks good now with the Bootes pre-release JSON:

@sandeepmistry Would you please close the issue if the code is satisfactory.
