This has been asked for a few times. Just to confirm that in latest S130, can I set the MTU size more than 23?
No you cannot yet change the MTU on any of the softdevices.
Does anyone know when the increased MTU size introduced by Bluetooth 4.2 will be available for nrf52832?
well nordic probably has a roadmap but they have carefully not said any more than it's being worked on and will come one day.
.. and the roadmap is that S132 alpha supporting long MTU and other 4.2 features was released today
An alpha release of the S132 supports new BLE 4.2 features, like the Long ATT MTU up to 512 bytes, see www.nordicsemi.com/.../56261
Note that the S132 v3 targets only the nRF52832, nRF52 DK and nRF52 Preview DK.
