The S110 supports up to 6 packets, but may be limited by the peer device. However, S110 is only Peripheral. S120 2.x.x can be both roles, chosen at boot time. S130 can be both roles simultaneously, but with limited buffers.

Ok, is it possible to use S110 softdevice in both master and peripheral? my application is just transfer data from side to another and S110 support 4 packet transfer per event at 7.5 ms connection interval.

Thanks alot for your guide

Unfortunately, there is not.

We plan to improve this on the S130. For more information you should contact the RSM for your area, if you don't know who that is please send me a PM and I'll let you know.

Hi Ahmed,

No, this is not possible.

However, in S120 2.x.x it is possible to disable and re-enable the SoftDevice as a peripheral (with 6 packet buffers) if you need to transfer lots of data. This is useful when doing Device Firmware Update (DFU) for instance.
