S120 softdevice packet per connection

[ahmed]

Hi every body,

Is there any way to increase the support packet per connection to more than 1 packet for S120 softdevice if i have just single slave and single master?

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.

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

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.
