softdevice s310 support central role?

Hi everyone.

We plan to work with nrf51422 and we need two BLE devices, One implements Peripheral role, another one implements Central role.

I would like to know if softdevice s310 support central role.

Hi

The S310 softdevice is the concatenation of the S210 ANT softdevice and the S110 peripheral BLE softdevice. So the S310 is capable to be an ANT device and a BLE peripheral at the same time.

If you need BLE peripheral device only, you should use S110 softdevice. If you need BLE central device only, you should use the S120 softdevice. If you do not intend to use ANT, i.e. only BLE, then it is sufficient to use nRF51822, which is compatible with all our BLE stacks, but not ANT stacks (S310 and S210). You can also use nRF51422 but it is slightly more expensive, but the nRF51422 is compatible with all our stacks, both BLE and ANT.

Thanks a lot!
