S130 V2 supports 8 connected peripherals. Refer to Chapter 11.4 "BLE role configuration " in the S130 SDS V2.

"The SoftDevice can be configured with one connections as a Peripheral and up to eight connections as a Central. The SoftDevice supports running one Advertiser or Broadcaster and one Scanner or Observer concurrently with the BLE connections."

you mean 52832 I assume and no currently that is also limited to one connection in the peripheral role, all Nordic's current BLE softdevices only allow multiple simultaneous connections if the nRF is running as a central.

I'm fairly sure this will change, although I have no idea when, but I'm ever hopeful the next version of the softdevice will support that (plus variable MTU and hopefully a production release of the iOt stack). Currently however, that's the way around it is.

Dear RK.

if so, is it possible to NRF52732? isn't there other choice? Thanks

if he wants to use the nRF51822 then he currently doesn't have a choice, it only supports multiple simultaneous connections as a central, so if the phones can't be peripherals, you can't currently do it.

Are you sure that you want to use the phones as a peripheral devices ? Not all of them support this feature.

maybe you should also take in account, how many Phones/Smart devices are supporting peripheral role, especially android stackoverflow.com/.../chipsets-devices-supporting-android-5-ble-peripheral-mode

I don't. Look at all the many central examples in the SDK.

RK.

if you have a sample code about central, please share it for me. Thanks.

Yes - make the 51822 a central, you can have up to 6 connected peripherals.
