The current stack is on S110, any plan to move it to S120(or even 130)? There are compatibility issues on the interface. But should be manageable.

Thoughts?

There are currently no plans to move to S120, no. The next major change would probably be migrating to the latest version of the SD first (SD7) once it's out of alpha, and then perhaps reviewing the API to see how we can extended it to other configurations.

Thanks Kevin. Do you mean S110 version 7? I am seeing an increasing need for dual role (which is addressed in 4.1 spec). I was thinking maybe S120/S130 might be a good step forward. Just my $0.02.

I second this. S130 would allow for both peripheral and central roles to be explored using the same SoftDevice. In theory, this would allow for two separate BT4.0 libraries, one for peripheral, and one for central; just like USB has one for device, and one for host. This would be a game changer for a BT4.0 project I'm working on in which one device must be a central.

I was told by Rohit in another thread that it would be updated to S110 v7.0 some time late last week — has that happened yet?
