L2CAP MTU size in S132 does not meet 4.2 specs

[fluent]

The Bluetooth 4.2 specifications allow for an L2CAP MTU size of up to 255 bytes. It looks like the CC2640 already supports the maximum MTU size of 255 bytes with a 248-byte payload and 7-byte L2CAP headers: processors.wiki.ti.com/.../CC2640_BLE_Throughput.

However, the S132 and other nRF SoftDevices are still limited to a maximum 23-byte MTU. Are the nRF SoftDevices compliant with Bluetooth 4.2 even though they don't meet this key specification? Does Nordic have any immediate plans to implement the increased 4.2 max MTU size?

Yes they're compliant with Bluetooth LE 4.2 because the spec allows for a large MTU but doesn't mandate it.

Oh, I didn't see that. Thanks!
